Polyvinyl Chloride Resin

Whatsapp Order

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.

Polyvinyl Chloride Resin (PVC)

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.
