    1. Detailed information

    Product Description

    HOWIN®RAS-302 is a quaternary random copolymer of styrene, acrylonitrile, glycidyl methacrylate and the fourth monomer, produced by bulk polymerization process. Its appearance is yellowish transparent granules.

     

    Application

    ² RAS-302 is completely compatible with styrenic resins and has GMA reactive functional groups, so it can be used as compatibilizer of styrenic resins and polyester resin alloys (such as ABS/PET, ABS/PBT).

    ² RAS-302 is suitable as heat stabilizer for PC / ABS alloy. It can inhibit the degradation of PC / ABS alloy and reduce or eliminate the surface silver wire of PC / ABS products.

    ² RAS-302 contains high reactive epoxy groups, which can inhibit the degradation and hydrolysis of polyester. It can improve the hydrolysis resistance and thermal stability of polyester and its alloys.
