PVC RESIN FOR CABLE
PVC RESIN FOR CABLE,
PVC Cable Compound, PVC Cable Raw Material, PVC For Electric Wires, PVC resin for cable insulation,
PVC because it has good physical, chemical, electrical, flame retardant performance, in the 1930s and 40s, foreign began to use soft PVC as the insulation material for wire, the development and application of PVC cable material in our country began in the 1950s. With the improvement of production capacity of PVC resin, plasticizer and industrial additives and the promotion and application of new varieties, the cable industry has a qualitative leap.
In the 21st century, with the enhancement of human environmental awareness and people’s attention to their own health, environmental issues have become the focus of human society. Many countries, regions and organizations have formulated strict standards and regulations to limit the use of harmful substances, especially RolS and REACH regulations. Looking for new methods and new processes, improve the utilization rate of resources, adapt to the requirements of environmental protection laws and regulations, environmental protection PVC cable materials emerged at the moment, and quickly become one of the themes of the current PVC cable materials development.
The increasing change and expansion of the market demand for wire and cable (referred to as cable), as well as the in-depth study of various new additives (such as flame retardant additives, smoke suppressor), promote the promotion and application of new technologies, new materials and new products of PVC materials. In a large amount of organic material (such as plastic, rubber) used in the cable industry, the amount of PVC cable material is the first organic material in our country.
The thermoplastic high-molecular polymer made by the suspension polymerization of vinyl chloride monomer. The molecular formula :- (CH2 – CHCl) n – (N: degree of polymerization, N= 590 ~ 1500). It is the most widely raw material used in plastic production. It has good chemical stability, corrosion resistance and water resistance.
