Molding and Extrusion Compounds, Heat Resistant Acrylic is a subcategory of Polyacrylates. It is specially formulated to molding and extrusion compounds, heat resistant. Its flexural modulus ranges from 150 to 440 MPa. Its tensile strength ranges from 9300 to 11500 MPa at break. Its flexural strength ranges from 12000 to 18000 MPa. Its compressive strength ranges from 15000 to 17000 MPa. Its Izod Impact strength ranges from 0.2 to 0.4 J/cm. Its elongation at break ranges from 2 to 10 %. Its hardness ranges from 94 to 100 Rockwell M. Its specific gravity ranges from 1.16 to 1.22. Its coefficient of thermal expansion ranges from 40 to 71 x 10^-6/°C. Its melting temperature ranges from 100 to 165 °C. Its molding pressure ranges from 5 to 30 MPa.

Polyacrylates, also known as Acrylic, is a thermoplastic polymer. It is known for its transparency, elasticity and resistance to breakage. Acrylic is commonly used in molding and extrusion compounds.
