♦Product description:
General-purpose thermoplastic low-smoke halogen-free flame-retardant polyolefin sheath material (SH-310), insulating material (SJ-320), oxygen barrier material (SG-100), mainly suitable for large public places requiring flame-retardant facilities Such as subways, nuclear power plants, high-rise buildings and airports. Once the cable is burned, only a small amount of smoke is emitted, no corrosive or hazardous gas is generated, which effectively protects the safety of people and equipment. At the same time, the product has good processing performance, and is widely used in power cables, communication cables, control cables, optical cables, etc.
