1.FEPWhat is the board?

 

FEP board,overview of perfluorinated plate: FEP is a perfluorinated ethylene propylene copolymer of tetrafluoroethylene and hexafluoropropylene. Crystallization

The melting point is 290 degrees and the density is 2.15g/cm3 (g/cm3). It is a relatively soft plastic with strong tensile strength.

Degree, wear resistance, creep resistance is lower than many engineering plastics. It has a wide temperature and frequency range that is chemically inert

Has a low dielectric constant (2.1s); has a good flame retardant coefficient, can prevent the spread of flame; has a good resistance

latency;Anti-aging performance;Low coefficient of friction at low temperatures below zero190 degrees can be used.

2.FEP plate/F-46 plateofCharacteristics

 

      1, physical properties: F-46 resin is a crystalline polymer, the crystallinity is lower than polytetrafluoroethylene.


     2, electrical insulation performance: its dielectric coefficient from low temperature to high temperature working temperature, from 50Hz to 1010Hz UHF wide range

The circumference is almost unchanged and low, only about 2.1S. The tangent of the media loss angle varies somewhat with frequency, but with temperature.

degree of change is not much. The volume resistivity is very high, generally greater than 10 of 15 Ω · m, and changes little with temperature, and is not affected by water and moisture.

The influence of gas. Arc resistance is more than 165s.

     3. Thermal performance: It can be used continuously in the temperature range of -85 to 200 ℃. Even at -200 ℃ and 260 ℃

Under the circumstances, its performance is not significantly degraded, can be used for a short time;

The loss of mechanical strength is large at a high temperature of 200°C.


    4. Chemical stability: Chemical stability is similar to polytetrafluoroethylene and has good chemical stability.


    5,Mechanical properties: compared with PTFE, hardness and tensile strength is slightly improved, the friction coefficient is also higher than PTFE

Slightly larger. It has good creep resistance at room temperature; but when the temperature is higherAt 100 ℃, the creep resistance is not as good as that of PTFE.

Ethylene.

 

    6. Other properties: good oxidation resistance in the atmosphere and high atmospheric stability. Radiation resistance is better than PTFE,

Slightly inferior to polyethylene.

 

3.Application areas

 

Widely used as corrosion structural materials, equipment anti-corrosion lining, vacuum sealing materials, electronic and electrical components, motor and instrument parts, electrical insulation materials,

Contact with strong corrosive medium, sealing and gasket materials of high pressure system, etc.
