CPVC Sheet
A CPVC (Chlorinated Polyvinyl Chloride) sheet is a rigid thermoplastic sheet made from chlorinated polyvinyl chloride resin. It is produced by processing CPVC material into flat sheets that offer excellent chemical resistance, high temperature stability, corrosion resistance, and mechanical strength. CPVC sheets are commonly used for chemical tank linings, industrial equipment, electrical insulation panels, and corrosion-resistant structures where durability and chemical resistance are required. CPVC sheets provide a dependable and durable solution. Designed to meet stringent industry standards, our sheets are ideal for both structural and lining applications in corrosive settings.
CPVC sheets are widely used in industrial, chemical, and construction applications because they can withstand harsh environments, corrosive chemicals, and elevated temperatures better than many standard plastic materials. These sheets are lightweight, easy to fabricate, and can be cut, drilled, welded, or machined for various industrial uses. Our CPVC (Chlorinated Polyvinyl Chloride) sheets are widely used in industrial environments where reliable performance under aggressive chemicals and elevated temperatures is essential.

CPVC resin is the primary raw material used to manufacture CPVC sheets. It is produced by chlorinating PVC resin, which increases the chlorine content and improves the material’s temperature resistance, chemical resistance, and mechanical strength. - Stabilizers
Heat stabilizers are added to protect the material during the manufacturing process. They prevent degradation of the CPVC resin when exposed to high temperatures during extrusion or molding. - Lubricants
Lubricants help reduce friction during processing and ensure the smooth flow of the material in manufacturing equipment. They also help improve the surface finish and uniformity of the CPVC sheet. - Impact Modifiers
Impact modifiers are added to improve the toughness and impact resistance of the CPVC sheet, making it less brittle and more durable during handling and use. - Fillers
Certain fillers may be added to enhance dimensional stability, strength, and cost efficiency. They help improve the overall structural properties of the sheet. - Processing Aids
Processing aids improve the melt strength and processing performance of the material, ensuring consistent sheet thickness and smooth production. - Pigments or Colorants
Pigments are added to give the CPVC sheet its color and appearance. They can also provide additional benefits such as UV resistance for outdoor applications.
