Foamed FEP Concentrate

RUIFLON Physically Foamed FEP Concentrate is an ideal material choice of gas injecting extrusion process foamed FEP for coaxial-cable and symmetrical cable.
1. Excellent fluororesin properties, low weight, good flexibility 
2. Lower dielectric constant and dielectric dissipation loss factor of the cable insulation
3. Low smoke, excellent inflaming retarding, corrosion resistance
4. Foamed FEP concentrate makes production more flexible, reduction of production costs
5. UL910、UL444.
6. RoHS compliant
