ULH-75 CMR 75℃ UL Standard CMR Grade Flame Retardant Network Cable Sheath Compound

ULH-75 CMR 75℃ UL Standard CMR Grade Flame Retardant Network Cable Sheath Compound is a high-performance flame retardant material used in the field of network communications. Based on polyvinyl chloride resin, it is made by adding additives such as plasticizers, stabilizers and high-efficiency flame retardants, and through fine mixing, plasticizing and granulating processes. It has flame retardant properties, meets the CMR level requirements in UL standards, and can remain stable at a temperature of 75°C. The cables have good surface quality when extruded and are suitable for a variety of network environments.

High flame retardant PVC sheath material for communication and security cables

UL high flame retardant PVC sheath material for network cable is made of polyvinyl chloride resin as the base material, adding plasticizers, stabilizers, flame retardants and other additives, and is prepared by mixing, plasticizing and granulating, which has aging resistance, low temperature resistance, flame retardant performance, and the surface is delicate/matte/grinding density The sand effect can be customized. The product meets ROHS2.0, REACH, NO-P, PAHS Class II, BPA-free and other environmental protection requirements.
