Material Notes:

Product Description: High Impact Polystyrene PS 325 is manufactured by continuous mass polymerization of styrene monomer. An elastomer is incorporated during polymerization to achieve impact resistance. It is generally opaque in color. It has medium flow characteristics with high tensile and flexural strength with medium heat deflection and Vicat temperatures.Typical Applications: PS 325 has been designed for the injection molding of appliance parts, toys, furniture parts, containers, blow molded parts and structural foam applications.Information provided by SABIC.
