Irradiation Crosslinkable LSZH Insulation Compound for BV Cable(105℃)
Irradiation Crosslinkable LSZH Insulation Compound for BV Cable(105℃)
Description
This material is used for halogen-free flame retardant(irradiation cross-linkable) 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 105℃, can pass the VD-1 combustion test(insulation thickness: 0.8mm).
Standard: UL 1581/UL 758; JB/T 10491
Application
- BV cable;
- Internal wiring of electronic and electrical equipment
