PVC Cable Compounds
Soft PVC cable compounds are the most economic polymer that used for cable of voltage lower than 10KV. Due to different temperature requirements, PVC insulation compounds are mostly customized for different cable and wire applications. It is very important to achieve a high filling rate of inorganic powders in order to get a competitive price. Evenly dispersing and distribution of various additives into melted polymer is the key to obtain a homogeneously gelation. Low process temperature is also required for a better quality.
