PVC plastic pellets are the most commonly used materials in the plastics industry and are widely used. With the improvement of people's living standards, the performance requirements of products are also gradually improved. Now the pipe fittings and pipes basically have good corrosion resistance. If you want to understand the corrosion resistance of PVC materials, you first need to understand what is PVC and what is the composition of PVC. PVC is the abbreviation of polyvinyl chloride. It is a polymer formed by the polymerization of vinyl chloride monomer in initiators such as peroxides and azo compounds, or by the mechanism of free radical polymerization under the action of light and heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is resistant to most inorganic acids (except fuming sulfuric acid and concentrated nitric acid), alkalis, most organic solvents (such as ethanol, gasoline and mineral oil, etc.) and inorganic salts, and is suitable for chemical anti-corrosion materials. Therefore, PVC plastic pellet materials are widely used in Chemical pipelines, pipe fittings and other building materials industries that require corrosion resistance.
