ETFE film is one of the fluoroplastics. It is widely used in various fields because of its good light transmittance, self-cleaning, insulation, moisture and heat resistance, and aging resistance.
ETFE fluoroplastic film contains fluorine, which is prone to thermal decomposition and corrosion of processing equipment and molds during hot processing.
Therefore, processing equipment and processes are different from ordinary thermoplastics. As China Plastic Extruder Supplier, China GWELL has successfully developed ETFE PFA PEEK CK film extrusion line with specially designed equipment and process technology.

China GWELL Product advantages

1. The thickness of ETFE fluorine film is generally 20 ~ 40 μ m. The width can reach 1300mm, the production line speed is 8-30m / min, and other specifications can be customized through negotiation;
2. ETFE membrane is high-quality alternative material in transparent building structures. Its unique self-cleaning surface makes it highly anti-fouling and easy to clean. Usually, rainwater can remove the main dirt;
3. ETFE film has anti-aging, corrosion resistance, long life, and so on. The general service life is 25-35 years;
4. ETFE membrane has lightweight, high fire rating, and will not drip during combustion;
5. ETFE film has high light transmittance, which can reach more than 90%;
6. Environmental protection and recyclability: ETFE membrane can be recycled to produce other ETFE products.

FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film. It has excellent chemical stability and excellent non-stick characteristics. The maximum service temperature is 200 ℃.
PFA (perfluoro alkylated) non-stick coating, like FEP, melts and flows during baking to form a non-porous film. The advantage of PFA is that it has a higher continuous service temperature of 260 ℃, stronger stiffness, and toughness, and is suitable for the application field of anti-adhesion and chemical resistance under high-temperature conditions.
FEP is a fluorinated ethylene-propylene copolymer. It is the toughest fluoropolymer resin. It can form a highly durable coating, has excellent chemical resistance, and can work continuously at 150 ℃.

Peek film is a kind of semi-crystalline high-performance special film made of PEEK polymer with a wide range of applications. Peek film has the characteristics of high-temperature resistance, lightweight, excellent mechanical properties, and durability, excellent radiation resistance, hydrolysis resistance, chemical resistance, excellent electrical insulation and wear resistance, good barrier performance and flame retardant performance, low toxicity of combustion products, low water absorption, halogen-free, and good processing performance.

Specific physical properties of PEEK films

1. Heat resistance: high-temperature resistant thermoplastic film, melting point 343 ℃, long-term service temperature recognized by UL in the United States is 260 ℃.
2. Excellent electrical performance and insulation performance: it still has excellent insulation and stable electrical performance in high temperature, high voltage, high frequency, high speed, high humidity, and other environments.
3. Flexibility: at present, it is among the best high-temperature resistant film products on the market, which is better than polyimide and polyphenylene sulfide film.
4. Solvent resistance: insoluble in most acid-base solvents.
5. Hydrolysis resistance: it can be used for a long time under 200 ℃ steam.
6. Radiation resistance: it has excellent resistance to all kinds of radiation and can withstand high-dose gamma rays without changing their physical properties.
7. Dimensional stability: extremely low water absorption and linear coefficient of thermal expansion
8. Wear resistance: the wear amount of the taberh10 wheel is 0.00027.
9. Flame retardancy: PEEK film with a certain thickness has self-flame retardancy, low smoke, and non-toxic combustion products.
