MMA / Styrene 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 450 to 460 MPa. Its tensile strength ranges from 8100 to 10100 MPa at break. Its flexural strength ranges from 14100 to 16000 MPa. Its compressive strength ranges from 11000 to 15000 MPa. Its Izod Impact strength ranges from 0.3 to 0.4 J/cm. Its elongation at break ranges from 2 to 5 %. Its hardness ranges from 80 to 85 Rockwell M. Its specific gravity ranges from 1.06 to 1.13. Its coefficient of thermal expansion ranges from 60 to 80 x 10^-6/°C. Its melting temperature ranges from 100 to 105 °C. Its molding pressure ranges from 10 to 30 MPa.

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