Premium PVC Compounds CAS: 9002-86-2
Polyvinyl Chloride (PVC) Compounds are versatile thermoplastic engineering materials produced by polymerizing vinyl chloride monomers and incorporating various additives such as stabilizers, modifiers, and fillers, followed by high-temperature mixing, plastification, and pelletizing. Renowned for their exceptional cost-performance ratio, outstanding modifiability, inherent flame retardancy (self-extinguishing), and excellent chemical resistance, PVC stands as one of the world's most widely used and successful plastics.
