Poly (perfluoroethylene propylene copolymer), also known as fluoroplastics, is polymerized with transparent granules (suspension polymer) or aqueous dispersion (lotion)
FEP (fluorinated ethylene propylene copolymer) non stick coating melts and flows to form a non porous film during baking, with excellent chemical stability and non stick properties. It can be used at a maximum temperature of 200 ℃ and is made of fluorine material, which has excellent properties and a smooth surface.
3、 Characteristics of FEP film
1. Non stick: Almost all substances do not adhere to the PTFE coating. The very thin film also exhibits good non adhesive properties.
2. Heat resistance: Teflon coating has excellent heat and low temperature resistance characteristics. It can withstand high temperatures up to 300 ℃ in a short period of time and can be used continuously between 240 ℃ and 260 ℃,
It has significant thermal stability and can operate at freezing temperatures without embrittlement, and does not melt at high temperatures.
3. Sliding property: Teflon coating has a low coefficient of friction. The friction coefficient changes when the load slides, with a value only between 0.05-0.15.
4. Moisture resistance: The surface of the PTFE coating does not come into contact with water or oil, and is not easily stained with solutions during production operations. If there is a small amount of dirt, it can be easily removed by wiping. Downtime
Short, saving time and improving work efficiency.
5. Wear resistance: It has excellent wear resistance under high load. Under a certain load, it has the dual advantages of wear resistance and non adhesion.
6. Corrosion resistance: Teflon is almost not corroded by drugs and can protect parts from any type of chemical corrosion.
Main characteristics of FEP film
1. Excellent adhesion and heat sealing properties with F4 and other materials
2. Below the melting point, it does not wet any object. Above the melting point,
3. It has good adhesion with F4 and metal. And self bonding (heat sealing) resistant to high and low temperatures -200~200 ℃
4. Non sticky, mixed with water and oil
5. Water contact angle θ=114 о
6. Electrical reliability and high insulation
7. The dielectric constant viscosity at high and low temperatures of 7, 60HZ-60MHz is 2.1. Even if the surface is damaged due to diving, no conductive tracks will be generated.
