Wire and Cable PVC Compound Granule PVC Sheath

PVC Sheath plays a crucial role in cable manufacturing. It is an insulation material mainly made of polyvinyl chloride resin, with stabilizers, lubricants, fillers and other additives added, processed through specific processes. It is widely used to wrap the conductor part of cables, forming a protective layer to improve the insulation performance, mechanical properties, and service life of cables.

The production process of PVC sheath material mainly includes steps such as raw material preparation, mixing, extrusion, cooling and solidification. Among them, mixing is to thoroughly mix PVC resin with other additives to form a uniform mixture; Extrusion is the process of melting a mixture in an extruder and subjecting it to high-pressure extrusion, forming the desired shape and size through a die; Finally, the extruded product is cooled and solidified through a cooling system to form the final PVC sheath material product.
