(1)HOWIN®RAS-302 can be used as compatibility between styrenic resins and polyester resin alloys (such as ABS/PET, ABS/PBT).
(2)HOWIN®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.
(3)HOWIN®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.
