产品描述
SABIC® 320NT is an ethylene-butene copolymer designed for wire and cable application. it is designed for high speed cable extrusion line, product use 320NT has excellent cable outlook, compare to the other polyethylene, 320NT is designed to reduce the use of additive during compounding, suggest the customer to optimize the silane and peroxide amount for 320NT based material, suitable for one-step silane crosslinking low voltage power cable insulation. 320NT contains no slip and no antiblock.
TYPICAL APPLICATIONS
Compounding for silane crosslinking low voltage power cable insulation, Compounding for halogen-free flame retardant cable, Other compounding
