PVC wire cable material is based on polyvinyl chloride
PVC wire and cable material is based on polyvinyl chloride, adding stabilizers, dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl trimellitate, etc. Plasticizers and inorganic fillers such as calcium carbonate, additives such as additives and lubricants, particles prepared by mixing, kneading and extruding.
Due to the use of stabilizers, plasticizers and various fillers and other additives in terms of environmental protection vary. Generally, it is measured by the testing methods and standards of ROHS or REACH. Divided into environmental protection and non-environmental protection PVC cable materials.
● Environmental protection pvc wire and cable material, that is to say, when the cable material is prepared
After success, test on ICP testing equipment with ROHS or REACH detection methods and standards. The content of heavy metals, DEHP, nonylphenol, polybrominated biphenyls and other prohibited substances and controlled substances in all material components must not contain or be within a certain amount. . Because the standards and requirements of each country are different, the corresponding environmental protection standards are different. The test unit is usually measured in ppm.
The stabilizer of environmental protection cable materials generally uses calcium zinc stabilizer.
The most important thing for PVC cable materials that meet the REACH standard is that DEHP16 substances cannot be used as plasticizers.
● Non-environmentally friendly PVC wire and cable materials
Non-environmentally friendly cable materials generally use lead salts as stabilizers, because they contain heavy metals such as lead, chromium, cadmium, mercury, barium, etc., which will cause great damage to the environment and human health, and are restricted by more and more countries or Prohibited use.
