PVC RESINS SG5
Introduction
PVC compound for soft wire and cable, based on PVC resin, is produced by high-speed kneading, mixing, plasticizing and granulation with adding plasticizer, stabillizers, fillers, lubricants and etc. The product has good electrical properties, chemical stability, is a cheap but qualified insulating material. Meanwhile, the Eco-friendly PVC cable compound which is produced by environmentally efficient compound stabilizer etc. is comply with EU RoHS 6 requirements. This series of products based on different models and temperature levels, respectively, can be used for manufacturing indoor wire, meter communication cable, various low-voltage wire and cable.
