PVC plastic pellets are the raw materials of plastics and have been widely used all over the world. As a chemical raw material, PVC plastic pellets are thermoplastic resins polymerized from vinyl chloride under the action of an initiator. PVC is a white powder with an amorphous structure, with a small degree of branching and poor stability to light and heat. When the temperature is above 100°C or after long-term exposure to sunlight, it will decompose to generate hydrogen chloride, and further autocatalytic decomposition, resulting in discoloration. , the physical and mechanical properties will also decline rapidly, and stabilizers must be added in practical applications to improve the stability to heat and light. PVC plastic pellets are homopolymers of vinyl chloride. In addition to these chemical components, PVC plastic pellets may also add some other special raw materials. Such PVC plastic pellets have chemical characteristics that vinyl chloride does not have.
