Power cord and plug material-PVC

Power cord and plug widely used in various fields, and plug the power cord is the main material is plastic PVC, under the following brief PVC:
PVC material that is PVC, it is the world's largest production of plastic products, cheap, widely used, PVC resin is white or light yellow powder. Can be added according to the different uses of different additives, PVC can present different physical and mechanical properties. Adding an appropriate amount of PVC resin, plasticizer, can be made into a variety of hard, soft and transparent products.
The density of pure PVC 1.4g/cm3, adding a plasticizer and fillers such as PVC plastic parts of the density is generally 1.15-2.00g/cm3.
PVC has good tensile, flexural, compression and impact resistance, structural materials can be used alone.
The softness of soft PVC, elongation, cold will increase, but the brittleness, hardness, and tensile strength will be reduced.
PVC has good electrical insulation properties, can be used for low-frequency insulation, chemical stability 也好. The poor thermal stability of PVC, prolonged heating can cause decomposition, release of HCL gas, the PVC color, so the narrow range of applications, the use of temperature is generally in the -15 to 55 degrees.
PVC industry is currently rapid development in the world, prospects, countries are optimistic about the potential of PVC and its environmental benefits, PVC is its superior performance to the world demonstrate the unique role and status is not replaced by any other product , social development needs of its environmental protection needs it, it is our human civilization and progress inevitable.
