What are the applications of PVC in wire and cable?

Due to its good physical, chemical, electrical, and flame-retardant properties, PVC has been used as an insulating material for wires in foreign countries since the 1930s and 1940s. The development and application of PVC cable materials in my country began in the 1950s. . With the improvement of the production capacity of PVC resin, plasticizer and industrial additives and the promotion and application development of new varieties, the cable industry has made a qualitative leap.

In the 21st century, with the enhancement of human environmental awareness and people's concern for 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 It is RolS and REACH regulations. Seeking new methods and new processes, improving resource utilization, and adapting to the requirements of environmental protection regulations, environmentally friendly PVC cable materials came into being, and quickly became one of the themes of current PVC cable material development.

The ever-changing and expanding market demand for wires and cables (referred to as cables), as well as the in-depth research on various new PVC additives (such as flame retardant additives, smoke suppressants), have promoted new technologies, new materials, and new products for PVC materials. promotional application. Among a large number of organic materials (such as plastics and rubbers) used in the cable industry, the amount of PVC cable materials ranks first in my country's organic materials.

PVC cable material is composed of polyvinyl chloride resin, stabilizer, plasticizer, filler, lubricant, antioxidant, colorant and so on. PVC plastic is also widely used as a sheath material for wires and cables due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance and good water resistance. By adding special performance additives or modifiers, it is possible to manufacture heat-resistant (105°C), cold-resistant, oil-resistant, flame-retardant, extra-soft and non-toxic PVC cable materials to meet special wire and cable requirements. product needs.

Polyvinyl chloride (PVC) plastics are multi-component plastics. According to different conditions of use, by changing the types and amounts of compounding agents, different types of PVC plastics for wires and cables can be prepared. Polyvinyl chloride (PVC) cable plastics can be divided into insulation grade cable materials and sheath grade cable materials according to their different uses on wires and cables. The protection level requires good heat resistance, while the insulation level requires good insulation.
