Polyvinyl Chloride (PVC)
A widely used thermoplastic polymer with excellent chemical resistance and durability, used extensively in automotive wiring, seals, and interior surfaces.
Overview
Polyvinyl Chloride (PVC) is one of the most widely produced synthetic plastics in the world. Available in rigid and flexible formulations (via plasticisers), it offers excellent chemical resistance, flame retardancy, and electrical insulation. In automotive manufacturing, PVC is used in wire and cable insulation, underbody coatings (plastisols), door seals, dashboard skins, floor mats, and roof liners. Its flexibility, low cost, and ease of processing make it a workhorse material in vehicle interiors and electrical systems. However, environmental concerns around chlorine content and plasticiser leaching are driving investigation into alternative materials in some applications.

Sustainability
Sustainability Rating
PVC can be mechanically recycled but chlorine content and plasticisers complicate the process. End-of-life incineration releases hydrogen chloride. Industry initiatives are working on greener alternatives and improved recycling.
