Excuse me: What are the components in pvc cable sheath material?

If you want to make cable materials that fully meet the national standard, then the content of PVC resin is about 50%; The main plasticizer dioctyl ester is also about 20%; Auxiliary plasticizer chlorinated paraffin is at most 6%; The filler calcium carbonate should not exceed 20%; Other stabilizers, lubricants and antioxidants account for 3%-5%.

Non-standard counterfeit PVC cable materials generally cut corners, and the methods generally include:

1:the content of PVC resin is low, generally less than 40%, the proportion of calcium carbonate filler is greatly increased, and the density of cable material is high;

2. Use low-grade or fake plasticizer to replace dioctyl ester, which is a cable material with low density but unqualified aging;

3. Adding a lot of plastic recycled materials, the density is not big, but the aging is unqualified; Because each batch of recycled materials is different, the data is not stable.
