HR2320 is one of the styrenic terpolymer(ABS) grade with improved toughness and heat resistance versus HIPS grades. HR2320 exhibits low shrinkage and good dimensional stability. HR2320 is widely used in general injection molding applications.Use this information as a guide to aid you in selecting the proper resin for your application. Application: furniture,automotive parts ,general injection molding,appliances casing and home appliances with heatresistance characteristics. Drying: Drying prior to processing is recommended in a desiccant dehumidifying hopper dryer. An inlet air dew point of - 20°F (-29°C) or below isrecommended to achieve a moisture content 0.1%. Typical drying conditions are 2 hours at 180° - 190°F (82°-88°C). Drying for 4 hoursat 160° - 170°F (71°-77°C) is also adequate.
