Impact Modified Molding and Extrusion Compounds Acrylic is a subcategory of Polyacrylates. The additative is added during the manufacturing process. Its elastic modulus ranges from 240 to 370 MPa. Its flexural modulus ranges from 200 to 430 MPa. Its tensile strength ranges from 5000 to 9000 MPa at break. Its flexural strength ranges from 7000 to 14000 MPa. Its compressive strength ranges from 4000 to 14000 MPa. Its Izod Impact strength ranges from 0.4 to 2.5 J/cm. Its elongation at break ranges from 4.6 to 70 %. Its hardness ranges from 35 to 78 Rockwell M. Its specific gravity ranges from 1.11 to 1.18. Its coefficient of thermal expansion ranges from 48 to 80 x 10^-6/°C. Its melting temperature ranges from 80 to 103 °C. Its molding pressure ranges from 5 to 20 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.
