In this article, pvc granules for wire and cable is our discuss. in first what is PVC resin?? the physical appearance of this granule is white powder, non-toxic and odorless. Relative density 1.35-1.46. It is thermoplastic, insoluble in water and ethanol, expandable or soluble in ether, ketone, fatty chlorohy-drocarbons or aromatic hydrocarbons with strong anti—corrosiveness and good dielectric property.
according to its application divided into soft and hard products. so can be processed into various plastic products.
mostly it used to produce transparent sheets, pipe fittings, blood transfusion equipment, soft and hard tubes, plates, doors and windows. Profiles, films, electrical insulation materials, cable jackets, blood transfusions and etc.
In cable industry, it have low temperature stability can easily stick to metallic surface when it’s heated. it is widely used in cable industry becouse it is resistant for heavy weather condition and easy processing and better electrical properties.
Cable PVC compounds are thermoplastic materials derived from processing polyvinylchloride compositions, produced as granules. So various properties are imparted to compounds depending on applications and item operation conditions. This is achieved by using plasticizers, stabilizers and modifiers in various combinations in compositions.
PVC based plasticizers have considerable mechanical strength and water resistance ,high thermal resistance to low temperatures. also use in the cable and conductor industry for manufacture of insulation and protective wire and cable sheaths. but the main final consumers of the PVC based cable and conductor products are energy and construction industries.
Wire and cable granules are even used in high temperature sensitive environments such as kitchens and related appliances. The use of PVC wires and cables comes only from their characteristics. Therefore, it is important to understand how their properties support the various applications of PVC wire and cable. Below are the five main characteristics of PVC wires and cables.
Pak chemical co (pishrochem) is supplier of PVC granules that are used in the production of a wide range of products. Because it has many practical features.
