Irradiation Crosslinkable HFFR TPE Insulation and Sheath(125℃)
Irradiation Crosslinkable HFFR TPE Insulation and Sheath(125℃)
Description
This material is used for halogen-free flame retardant(irradiation crosslinkable) wire and cable insulation material. It is made of high- quality resin, flame retardant, antioxidant agent and cross-linking agent by mixing granulation. None-halogen property makes the materials non-toxic when burning; it has excellent flame retardancy, good physical and mechanical properties and processing performance; its heat resistance level is 125℃, can pass the VW-1 combustion test.
Standard: BS EN 50525/2014
Application: EN-SS/Flexible wire
