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.

PVC cables are now widely used in various electrical applications because of the advantages of PVC such as chemical resistance, water resistance, heat resistance, robustness, elasticity and flexibility. Due to its impeccable properties, PVC is mainly used for wire insulation or cable jackets.

PVC cable compounds feature diverse temperature resistance levels and formulas, incorporating numerous additives. Achieving a uniform melt requires even dispersion of these additives, and maintaining low processing temperatures is crucial for high-quality products.

Co-Kneader offers key features to meet these mixing needs:

The screw proﬁle can be changed by adjusting the order of the segmented screw elements and liners, allowing the same machine to handle various formulations
Multiple ﬂights and pins enhance kneading, ensuring even distribution of additives in the melt
Temperature probes inserted into pins in each processing zone provide accurate real-time melt temperatures, enabling tight control over the process temperature
