PVC Coating
category
PVC (polyvinyl chloride) coating applies plastisol or organosol formulations containing PVC resin (40–60%), plasticizers (DOP or DINP at 30–50 phr), stabilizers, and fillers onto woven or knitted substrates via knife-over-roll or calender at 160–190°C. Add-on weights of 100–600 g/m² produce highly durable, stiff coated fabrics. Tensile strength exceeds 1,000 N/5cm for heavy industrial grades. Phthalate plasticizers are increasingly restricted under EU RoHS and REACH, driving adoption of bio-based plasticizers (DOTP, citrates). PVC-coated fabrics represent a $4.5 billion global market.
Role
Cost-effective, durable coating system widely used in truck tarpaulins, banners, awnings, inflatable structures, and protective clothing, offering excellent UV resistance and 10–20 year outdoor service life.
