PVC

Polyvinyl Chloride (PVC) is a synthetic plastic polymer produced from the polymerization of vinyl chloride monomers. As one of the most widely used thermoplastics globally, it is valued for its adaptability, durability, and strong resistance to moisture, heat, and various chemicals. PVC finds use across numerous industries, including construction (for items like piping and siding), apparel, packaging, electrical insulation, and automotive components. In its pure state, PVC is both colorless and odorless, though it is often modified with plasticizers and other additives to enhance flexibility and ease of processing. It is also recyclable, making it a more sustainable material choice in many applications.
Organic peroxides are commonly used as initiators in the polymerization of vinyl chloride monomers to produce PVC. They help start and control the free-radical polymerization process, ensuring consistent molecular weight and product quality. To obtain a wide spectrum of polymerization temperatures, combinations of different peroxides are often applied in practice.
The most commonly used initiators in PVC production are low-temperature initiators such as EHPC, CPND, TBPND, TMHP and TAPPI.
