Topadd CRA is our unique PVC impact modifier developed by our R&D Center, which is an interpenetrating network copolymer (IPN). Its main function is to enhance the impact strength of PVC finished products under low temperature and to promote the fusion property of PVC blend. It can endow the best impact-resistance and toughness to PVC final products than other PVC impact modifiers.
In addition, CRA series have better weatherability owing to that it has not any chemical double bond. CRA series are insoluble in water and ethanol, but soluble in acetone and chloroform.
PVC Impact Modifier CRA Series include below grades:
(1) Replace opaque MBS impact modifier;
(2) Replace AIM(acrylic impact modifier);
(3) Replace CPE+AIM(acrylic impact modifier) with less dosage;
(4) Replace CPE+PA(processing aid) or 100% CPE with less dosage.
