Material Notes:

Polystyrene 945 is designed for injection molding applications requiring superior toughness. This polymer is a high impact polystyrene with excellent gloss and falling dart properties. The impact and gloss levels achievable with 945 allow design engineers to use this polymer instead of more expensive engineering polymers. Applications such as industrial guards, appliance housings, toys, and industrial spools are candidates for 946.Information provided by Total Petrochemicals, Inc.
