CAM Series Product Desc ription
CAM is a new grade impact modifier for rigid PVC products, such as PVC profiles, PVC pipes, PVC panels etc. It is a copolymer which is grafted by chlorinated polyethylene and acrylic ester monomer. It offers better fusion than using chlorinated polyethylene only. It can improve the impact strength of rigid PVC under normal temperature even much lower temperature with excellent weatherable properties.
