Separation membrane: used for the separation of various gases, such as hydrogen/nitrogen, nitrogen/oxygen, carbon dioxide/nitrogen, or methane, to remove moisture from air hydrocarbon feed gases and alcohols. It can also be used as a pervaporation membrane and ultrafiltration membrane. Photoresist: Some polyimides can also be used as photoresists. There are negative and positive adhesives, and the resolution can reach sub micron level. When combined with pigments or dyes, it can be used for color filter films, greatly simplifying the processing steps. Application in microelectronic devices: used as a dielectric layer for interlayer insulation, and as a buffer layer to reduce stress and improve yield. As a protective layer, it can reduce the impact of the environment on the device and also act as a shield for alpha particles, reducing or eliminating soft errors in the device. Polyimide, an alignment agent used in liquid crystal displays, plays a very important role in the materials of TN-LCD, SHN-LCD, TFT-LCD, and future ferroelectric liquid crystal displays.Electro optical materials: used as passive or active waveguide materials, optical switch materials, etc. Fluorinated polyimides are transparent in the communication wavelength range, and using polyimide as a chromophore matrix can improve the stability of the material. Moisture sensitive materials: The principle of linear expansion due to moisture absorption can be used to make humidity sensors. Storage method 1.

In glass thinning and etching processes, a special protective film is required to protect non processed areas. UV reducing film (also known as UV film) is designed for this purpose, and PO (polyolefin) is one of the high-performance substrates.It is like an "intelligent shield" that firmly adheres to provide protection during processing. After processing, it can be easily and completely peeled off by UV light irradiation without leaving any residue.⚙️ Core feature: How does it work?The excellent performance of UV reducing film in glass etching process is attributed to its unique design:UV debonding and non-destructive peeling: this is its core function. Before exposure to ultraviolet (UV) light, the tape has high adhesion (such as initial adhesion of PO material up to 1300 gf/25mm), which can firmly adhere to the glass surface and prevent etching solution from penetrating. After completing the protection task, the adhesion will instantly decrease significantly through UV light irradiation, reaching a nearly non stick state (such as PO material dropping to 25 gf/25mm after debonding), making it easy and non-destructive to peel off, effectively avoiding the risk of glass substrate cracking due to uneven tearing force.Excellent acid and alkali corrosion resistance: Highly corrosive solutions such as hydrofluoric acid (HF) and hydrochloric acid (HCL) are often used in etching processes. This type of protective film can effectively resist the erosion of these chemicals, preventing them from warping, peeling, or seeping during complex acid washing processes.No residual glue, high cleanliness: Excellent UV debonding process and colloidal formula ensure that after the film material is peeled off, the glass surface can maintain its original cleanliness without adhesive residue. This is the key to ensuring the quality of subsequent processes and product yield, and it is also an important reason why PO protective films are highly favored in high-end applications.🛡️ PO substrate vs. PET substrate: how to choose?The performance of UV thinning film is closely related to the substrate (i.e. the main material of the film), and the common ones are PO and PET (polyester film), which have significant performance emphasis in glass thinning etching process. You can choose according to your specific application scenario:Characteristics PO (Polyolefin) PET (Polyester)Base material characteristics: The material is soft, with excellent ductility and cushioning properties. The material is relatively hard, with good stiffness, better temperature resistance, and dimensional stabilityThe key process is manifested in glass thinning/etching, which can provide excellent adhesion and buffering protection; Excellent acid resistance performance, some products can be sprayed under mixed acid for more than 200 minutes without acid leakage or detachment. They perform well in cutting, grinding and other processes that require high fixation force, with good processing performance and easy punching and cuttingThe application scenarios are mainly recommended for complex chemical etching, glass thinning, and strengthening processes. Its excellent acid resistance and flexibility make it the preferred choice for single-sided thinning of mobile phone glass covers, OLED/TFT panels, and other fields, mainly used for high-strength cutting, grinding, and other processes. It is also suitable for glass thinning protection, but in terms of acid resistance, conventional PET film may not be as good as PO filmViscosity change (gf/25mm) approximately 1300-1600 before UV irradiationAbout 25-30 after UV irradiation and about 1100-2200 before UV irradiationAbout 6-7 after UV irradiationReference temperature resistance: Long term temperature resistance of about 80 ℃Short term temperature resistance can reach 90-120 ℃, and long-term temperature resistance is about 80 ℃Short term temperature resistance of about 120 ℃Adhesive force (gf/25mm) refers to the adhesive force on a width of 25mm, with higher values indicating stronger initial adhesion.🔍 Application process: from attachment to peelingUnderstanding how it operates in actual production helps to better understand its value:Attachment: Before etching, apply the UV reducing film evenly to the glass surface that needs to be protected (such as the display area), and ensure that the two are tightly adhered without bubbles.Etching: Chemical etching is performed, during which the protective film, with its high viscosity and acid resistance, effectively blocks the etching solution from corroding non target areas.UV irradiation: After etching is completed, use UV curing equipment to irradiate the protective film. The photoinitiator in the adhesive layer reacts rapidly under UV light irradiation, causing cross-linking or changes in the molecular structure of the adhesive layer, resulting in a significant decrease in viscosity.Peel off: After UV irradiation, the protective film with extremely low viscosity can be easily and completely peeled off from the glass surface without leaving any residue, completing the protective missionPlasma thermal spraying masking tape
Plasma thermal spraying (including plasma spraying, supersonic flame spraying HVOF, flame spraying, etc.) is a high-temperature and high-speed process that requires much stricter requirements for masking tape than ordinary PCB furnace protection. The core feature of this type of tape is that it is made of glass fiber cloth as the substrate, coated with high-temperature resistant silicone adhesive, and some high-end products also have a composite aluminum foil layer to enhance heat radiation resistance.The following are mainstream tape solutions for this special process:🔥 Comparison of core products of plasma thermal spraying masking tapeTape type/model Core structure and characteristics Temperature resistance Main application scenarios Typical appearanceSilicone rubber/fiberglass cloth composite tape (universal type) is based on high-strength fiberglass cloth coated with high-temperature resistant silicone.

Electrical insulation tape is the most fundamental and critical material in the field of electrical engineering. Its core function is to isolate current, prevent short circuits and leakage, and provide certain mechanical protection. It may seem simple, but tapes made of different materials and structures have significant differences in temperature resistance, pressure resistance, and flexibility. Choosing the wrong tape may leave safety hazards.📋 Types and Comparison of Mainstream Electrical Insulation TapeAccording to the different substrates, electrical insulation tape can be divided into the following categories, and you can quickly screen according to your own needs:Substrate type represents product examples, core characteristics and temperature resistance levels, typical application scenarios, key performance parametersSoft PVC tape Desha 53988, 3M Super 33+universal type, most commonly used. Good elasticity, comfortable hand feel, flame retardant, available in multiple colors for easy identification. The temperature resistance level is usually 80-105 ℃. Insulation wrapping, joint treatment, phase identification, and daily maintenance of wires and cables. Breakdown voltage:~7kVTensile strength:~25 N/cmPolyester film tape Intertape 51588, SynTape ® PM.099 is thin and strong. Thin thickness but high dielectric strength, tear resistance, and solvent resistance. The temperature resistance level is usually 130 ℃ (Class B). The interlayer insulation of transformer and motor coils requires precision windings with small space occupation, as well as scenarios that require immersion resistant paint. Breakdown voltage: 5 kVTensile strength: 40-44 N/cmPolyimide tape (Golden Finger tape) Su Rui Electric's high-temperature resistant tape is the king of high-temperature resistance. Ultra thin, resistant to high and low temperatures, and resistant to acid and alkali solvents. The temperature resistance level can reach up to 180 ℃ (H level) or even 260 ℃. Insulation protection in high temperature environments, such as lithium battery lug fixation, SMT welding shielding, and high temperature coil wrapping. Long term temperature resistance: 260 ℃Excellent chemical resistance🔍 Interpretation of Key Performance IndicatorsWhen selecting, one should not only look at the name, but also pay attention to these core parameters that determine quality:Voltage endurance/breakdown voltage: This is the most critical insulation indicator. High quality PVC tape can usually reach 6-7 kV or above. For high-voltage scenarios, it is essential to choose products that have undergone withstand voltage testing.Temperature resistance level: directly determines the service life of the tape. Use letters to indicate the maximum temperature for continuous operation: Class A (105 ℃), Class B (130 ℃), Class F (155 ℃), Class H (180 ℃). Motors and transformers must have at least Class B or higher internal components.Adhesive type:Rubber: It has strong initial adhesion and easy bonding, but is sensitive to oil and chemical solvents. Suitable for regular bandaging.Acrylic acid: high temperature resistance, aging resistance, and good chemical resistance, making it the preferred choice for oil resistant tapes for equipment such as anic silicon: has the highest temperature resistance level (above H level), and there is no residual adhesive when peeled off. Suitable for extremely high temperatures or situations that require clean chanical strength: including tensile strength and elongation. In scenarios where bundling and fixation are required (such as the end of a motor coil), the adhesive tape needs to have sufficient tensile strength (e.g.>30 N/cm) and ductility to ensure that the long-term bundling does not loosen.💡 Combining your previous needs (transformer scenario)Based on your previous question about "transformer oil resistant tape", the selection process will be clearer:If it is interlayer insulation for transformer coils, what you need is polyester film tape (such as Intertape 51588) or glass cloth tape. They not only have a temperature resistance of B level or above (130 ℃+), but more importantly, acrylic or cured rubber adhesives can resist long-term immersion in transformer oil, and the thin design does not affect heat dissipation.If it is external wiring terminal wrapping: a universal high-quality PVC tape (such as 3M Super 33+or Desha 53988) is sufficient. It has good flexibility and can tightly fit various shapes of connectors, providing reliable insulation and mechanical protection.If it is insulation for high current busbars (copper bars): thicker heavy-duty PVC tape (such as 3M Super 88, thickness 0.22mm) or professional self-adhesive silicone rubber tape is required, which can provide stronger wear resistance and insulation thickness.⚠️ Important NoticeAll industrial grade electrical insulation tapes should comply with the corresponding international or national standards. When selecting, you can pay attention to whether the product has passed certifications such as IEC 60454, UL 510, or VDE, which are the basic guarantees of its performance and reliability.Plasma spraying tape

Epoxy thermoplastic composite film is a high-performance adhesive material, whose core feature is to combine thermosetting epoxy resin with thermoplastic resin (such as polysulfone, nylon, etc.), usually in the form of a thin film, mainly used for bonding and manufacturing composite materials.To help you understand more clearly, we can look at the following aspects:1. What is it? ——A type of adhesive film that combines rigidity and flexibilityEpoxy resin itself is hard and heat-resistant, but relatively brittle; And thermoplastic resin is very flexible. The combination of the two is to allow epoxy resin to retain its high strength and heat resistance advantages while increasing toughness through thermoplastic resin, solving its "brittle" weakness.Form: It usually exists in the form of a solvent-free film, with very precise thickness and resin content, making it easy to operate and process control.Curing: When in use, it requires a chemical reaction at a certain temperature to cure (crosslink) and ultimately form a strong bond.2. Core advantage: Why add thermoplastic resin?Adding thermoplastic resins (such as polyethersulfone, nylon, etc.) to epoxy resins for modification mainly brings three major benefits:Significantly improving resilience: This is the primary objective. Research has shown that adding 20% thermoplastic resin can increase the impact strength of composite materials by 154% and the bending strength by about 50%.Ensure high strength: While increasing toughness, it can still maintain the excellent cohesive strength and heat resistance of epoxy resin. For example, a patented product has been toughened with thermoplastic resin, increasing its temperature resistance level to 175 ℃ and achieving a glass transition temperature (Tg) of 190 ℃.Good process performance: The adhesive film is easy to lay and suitable for bonding large and complex structural components. There are almost no volatiles during curing, ensuring the density of the adhesive layer.3. Main application scenariosDue to its excellent comprehensive performance, this adhesive film is mainly used in high-end fields:Aerospace: This is the most important application field. Used for manufacturing and bonding aircraft structural components (such as wings, fuselage), radar antenna covers, engine nacelles, etc., it needs to withstand extremely high stress and temperature changes.Rail transit: used for the manufacturing and assembly of lightweight components for trains, such as bonding carbon fiber bodies and interior parts, to meet the weight reduction and strength requirements of high-speed trains.Sports equipment and electronics: also used for manufacturing high-performance sports equipment (such as tennis rackets, bicycle frames), as well as for bonding electronic components that require high reliability.4. Typical product casesTo give you a more intuitive understanding, here are two typical products on the market:Product Name Key Features Typical Application SourcesThe Henkel LOCTITE EA 9658 is designed specifically for engine nacelles, with three times the toughness of similar products, and can be used for a long time at 177 ℃ (tested for 6000 hours).

Working temperature range -55 ℃ to 149 ℃, can be co cured with prepreg. Aerospace (composite material surfaces requiring lightning protection)summarySimply put, "epoxy thermoplastic composite film" is a high-performance film adhesive made by combining strong and tough epoxy resin with flexible thermoplastic resin. It not only retains the heat resistance and high strength of epoxy resin, but also solves its brittleness problem through thermoplastic resin, making it an indispensable key material in high-end manufacturing industries such as aerospace.
