PVC resin for cable
PVC resin for cable,
PVC resin for wire cable, PVC resin SG-3, PVC Resin SG3,
Cable material generally requires high molecular weight, and the absorption of plasticizer is easy, often use suspension method loose type, high purity, less impurities, less fish eye type PVC resin. Generally, SG-1 or SG-2 is used, but at present, these two resins are less, so many cable materials are made of SG-3. SG-1 type resin should be used for advanced electrical insulation materials, SG-2 and 3 type can be used for general electrical insulation materials. SG-1 type should be selected for cable material with high heat resistance grade.
Features thermo plasticity, being insoluble into water, gasoline and alcohol, swelled or dissolved into ether, ketone, chlorinated aliphatic hydrocarbons, and aromatic hydrocarbon, high resistance to corrosion, and good dielectric property.
Application
PVC Resin SG-3 Application to :
1. PVC profile
Profiles are the field of PVC consumption in domestic country, about 25% of total PVC consumption, mainly for making doors and windows and energy-saving materials, and their application is still large and growth.
2. PVC pipe
PVC pipes are the 2nd largest consumption industry,The consumption is 20% of total production capacity in Domestic of China, the PVC Pipe .
3. PVC film
The PVC film filed is the 3rd big quantity consumption , it is about 10% of total production capacity.
