PVC / Acrylic Blends Molding and Extrusion Compounds PVC is a subcategory of Polyvinylchloride. The additative is added during the manufacturing process. Its elastic modulus ranges from 340 to 370 MPa. Its flexural modulus ranges from 350 to 380 MPa. Its tensile strength ranges from 6400 to 7000 MPa at break. Its flexural strength ranges from 10300 to 11000 MPa. Its compressive strength ranges from 6800 to 8500 MPa. Its Izod Impact strength ranges from 1 to 12 J/cm. Its elongation at break ranges from 35 to 100 %. Its hardness ranges from 106 to 110 Rockwell R. Its specific gravity ranges from 1.26 to 1.35. Its coefficient of thermal expansion ranges from 44 to 79 x 10^-6/°C. Its molding pressure ranges from 2 to 3 MPa.

Polyvinylchloride, also known as PVC, is a thermoplastic polymer. Common trade names are Geon and Viclon. copolymer Its flexible grades are easy to process; and its rigid grades are low cost and have high dielectric strength, excellent outdoor stability, good chemical resistance, and good moisture stability. Both grades have low heat resistance. It is commonly used in pipes and fittings, wire and cable insulation, extruded films and sheets, and medical applications.
