Product Description:
POLYCIMA-80Q90V is a highly flame-retardant, low-smoke zero-halogen (LSZH) polyolefin material that complies with regulatory requirements such as RoHS, SVHC, 16P, and PAHs. It exhibits excellent mechanical and physical properties, electrical properties, and processing characteristics.
Product Applications:
It can be used in optical fiber drop cables, sheaths, wire insulation and sheaths, etc. Extrusion methods include pressure extrusion, semi-tube extrusion, and tube extrusion. Some products can also be injection molded. Compared with similar products from other manufacturers, it offers stable flame retardancy, a finer surface appearance, and better scratch resistance.
