Performance and Uses
Polyvinyl Chloride (PVC) resin is a white, amorphous powder with a low degree of branching and good mechanical properties. It offers excellent corrosion resistance, weather resistance, non-toxicity, biocompatibility, transparency, barrier properties, electrical insulation, and flame retardancy. PVC is widely used in construction (pipes, window and door profiles, flooring), packaging (food packaging, bottles, films), electrical and electronics applications (wire and cable insulation and sheathing), and chemical and corrosion-resistant equipment (laboratory ware, corrosion-resistant piping, and storage tanks). The product complies with GB/T 5761-2018.
