Study on the Formula of the Environmental Friendly 90 °C PVC Sheathing Compound

Abstract:

The formula of the environmental protection PVC sheathing compound used for wires and cables contains: the base resin, composite stabilizer, plasticizer, filler, antioxidant and lubricant. In this paper, each component’s effects on the performance of the sheathing compound were studied. The optimized formula was established as: 100.00 phr PVC SG-3, 7.80 phr Ca/Zn stabilizer, 38.00 phr DIDP, 11.00phr DOTP, 34.50 phr ground calcium carbonate, 0.40 phr Bisphenol A, 0.70 phr lubricants, and 1.50phr coloring agent. The product properties were tested. The results indicate that this formula system contain neither heavy metals such as lead, cadmium, hexavalent chromium and mercury, nor polybrominated biphenyls and their ethers, which can cause significant damage to people and the environment. The product property completely meets the performance standards set for the environmental protection 90 °C PVC sheathing compound.
