Karakteristika for og anvendelser af PVC's fem plastmaterialer til generelle formål
Polyvinyl chloride is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization.
PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact-resistant agents and other additives in actual use. It is non-flammable, high-strength, weather-resistant and has excellent geometric stability. Polyvinyl chloride is generally used in plastic wrap, plastic shoes and leather products.
Polyvinyl chloride is generally used in plastic wrap, plastic shoes and leather products, films, cables, and plastic bags. Its production process is mainly divided into calcium carbide method and ethylene method. With the high energy consumption cost and environmental protection pressure of calcium carbide method PVC enterprises, ethylene method PVC will be the general trend.
The current PVC production process has been able to ensure that the residual monomer content in PVC is extremely low, and qualified PVC can be safely used in food packaging and other aspects.
