The difference between environmentally friendly and non-environmentally friendly PVC wire and cable materials:
PVC wire and cable materials are based on polyvinyl chloride as the base resin, adding stabilizers, dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl trimellitate and other plasticizers, as well as inorganic fillers such as calcium carbonate, additives and lubricants, etc., and processing various plastic particles.
PVC cable material particles vary due to the different environmental protection of stabilizers, plasticizers and various fillers used. It is divided into environmentally friendly and non-environmentally friendly PVC wire and cable materials.
1. Environmentally friendly PVC wire and cable materials
After success, use standard testing methods to test on the test equipment. The content of heavy metals, DEHP, nonylphenol, polybrominated biphenyls and other banned substances and controlled substances in all material components cannot be contained or within a certain weight. Because the standards and requirements of each country are different, the corresponding environmental protection standards are different. The test unit is generally measured in ppm.
The stabilizer of environmentally friendly cable materials is generally calcium zinc stabilizer. The most important thing for PVC wire and cable materials that meet the standards is that DEHP16 substances cannot be used as plasticizers.
2. Non-environmentally friendly PVC wire and cable materials
Non-environmentally friendly wire and cable materials generally use lead salts as stabilizers. Because they contain heavy metals such as lead, chromium, cadmium, mercury, and barium, they will cause great harm to the environment and human health, and are restricted or banned by more and more countries.
