PVC Resin
PVC Resin (Polyvinyl Chloride Resin) is a white, odorless powder widely used as the base material in the production of both rigid and flexible PVC products. It is produced by polymerizing vinyl chloride monomer (VCM) and is categorized by K-value, which defines molecular weight and processing characteristics. PVC resin is valued for its durability, chemical resistance, electrical insulation, and flame retardancy. It is one of the most versatile plastics used across multiple industries including construction, electrical, automotive, packaging, and healthcare.
Primary Uses
Construction Industry
Used in rigid applications such as pipes, fittings, window and door profiles, panels, and roofing sheets.
Employed in flexible PVC for flooring, wall coverings, and waterproof membranes.
Valued for weather resistance, chemical stability, and low maintenance.
Electrical Industry
Utilized in cable insulation and sheathing due to its excellent electrical insulation properties.
Provides flame retardancy and mechanical protection for wires and cables.
Packaging Industry
Used in producing blister packs, rigid containers, shrink films, and cling films.
Offers transparency, formability, and good barrier properties.
Automotive Industry
Applied in interior trims, dashboards, underbody coatings, and door panels.
Flexible PVC made from resin is used for seals, hoses, and insulation components.
Healthcare & Medical Industry
Used in manufacturing blood bags, IV tubing, catheters, and oxygen masks (medical-grade flexible PVC).
Offers biocompatibility and sterilizability when properly formulated.
Consumer Goods
Used in making footwear soles, synthetic leather, toys, and household items like hoses, mats, and containers.
Secondary Uses
Agriculture
Used in making irrigation pipes, greenhouse films, and water storage tanks.
Furniture
Applied in PVC edge bands, synthetic leather upholstery, and foam boards.
Textiles
Used in coated fabrics and tarpaulins for water resistance and durability.
Stationery
Applied in file covers, binders, and other office supplies for flexibility and printability.
Recreational & Safety Equipment
Used in life jackets, raincoats, protective gloves, and sports equipment covers.
