Product Description:
This product is made of high-purity resin as the base material, with halogen-free flame retardant, cross-linking agent, antioxidant, etc. mixed and extruded into granules. It has excellent performance such as halogen-free, heat-resistant, flame-retardant, low-smoke, and weather-resistant. It has no precipitation pollution, meets the relevant requirements of Rohs, etc., and is easy to extrude and process.
Application Field:
B1 grade wires for various indoor wiring.
