Polyvinyl Chloride  (PVC)

PVC is widely used in the production of electrical components, automotive parts, and construction materials, thanks to its excellent chemical stability, weather resistance, and mechanical strength. The choice of organic peroxide initiators and their dosage has an important role in determining the quality of the final PVC product, influencing factors such as strength, durability, and consistency.

Organic peroxide initiators play a crucial role in PVC production by enabling the free radical polymerization of vinyl chloride monomer (VCM). These initiators decompose under heat, releasing free radicals that initiate the chain reaction, forming long polymer chains of PVC. 

To select the appropriate organic peroxide initiator for PVC production, consider the desired PVC resin properties, the polymerization temperature, and the initiator's reactivity and safety characteristics. The chosen initiator should match the specific requirements of the PVC grade (rigid or flexible) and the desired K-value.
