CAM introduction


Introduction

CAM is a new PVC impact modifier, which is an interpenetrating network copolymer formed by grafting slightly chlorinated HDPE with acrylate. Its main function is to enhance the impact strength of PVC finished products under low temperature and endows the better toughness and impact modifier in low temperature. At same time, it can improve the weather ability of products. CAM is mainly used in PVC pipes, fittings and injections.
