White Powder Polyvinyl Chloride Powder Electrical Insulation For Wire Cable
Description
Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran and has two different shapes:
1. Rigid :
Used in: construction for pipe, doors and windows, making bottles (non-food packaging) and cards (such as bank or membership cards).
2. Flexible.
Used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, and many applications where it replaces rubber. With cotton or linen, it is used to make canvas.
Applications:
1. PVC resin SG3 is used for soft material, pvc sheet, pvc film, leather,tubes, table cloth, tape.
2. PVC resin SG5 is general type.
Mainly used for pipe and windows structural section.
Also it can be used for electric insulation material, tubes, artificial leather.
