Foamed FEP

Item No.: 3
Physically Foamed FEP is often used in low smoke flame-retardant wire or military transmission cable in high temperature.
1.Excellent fluororesin properties, low weight, good flexibility 
2.Lower dielectric constant and dielectric dissipation loss factor, minimum high-frequency signal distortion
3.Low smoke, excellent inflaming retarding, corrosion resistance
4.NFPA 262、UL444。
5.ROHS compliant
