Product Description:
B1-level oxygen-insulating layer material is made of high-purity resin as the base material, with halogen-free flame retardants, antioxidants, etc. mixed and extruded into granules. It has excellent performance such as halogen-free, heat-resistant, and weather-resistant, has no precipitation pollution, meets the relevant requirements of Rohs, and is easy to extrude and process.
Application Areas:
various indoor wires and cables. B1-level cables used in dense public places such as super-high-rise buildings and first-class high-rise buildings in civil buildings, shopping malls, schools, subway stations, airports, gymnasiums, hospitals, etc.
