Molding and Extrusion Compounds PVC is a subcategory of Polyvinylchloride. It is specially formulated to molding and extrusion compounds. Its elastic modulus ranges from 212 to 600 MPa. Its flexural modulus ranges from 334 to 450 MPa. Its tensile strength ranges from 6500 to 9000 MPa at break. Its flexural strength ranges from 11500 to 17000 MPa. Its compressive strength ranges from 9000 to 22000 MPa. Its Izod Impact strength ranges from 1 to 10 J/cm. Its elongation at break ranges from 4 to 100 %. Its hardness ranges from 109 to 117 Rockwell R. Its specific gravity ranges from 1.39 to 1.58. Its coefficient of thermal expansion ranges from 52 to 78 x 10^-6/°C. Its melting temperature ranges from 110 to 127 °C. Its molding pressure ranges from 15 to 40 MPa.

Polyvinylchloride, also known as PVC, is a thermoplastic polymer. Common trade names are Geon and Viclon. chlorinated poly(vinyl-chloride) 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.
