Product Description
SAMSUNG TOTAL CH72W is a polypropylyene compound with ultra-weatherability, ideal for use in outdoor products/components such as the exteriors of air conditioners. This grade is polypropylene with a CaCO3 inorganic filler, so rigidity and heat resistance have been improved. This product is manufactured with a variety of base PPs, including HIPP (High Isotactic Polypropylene), using SAMSUNG TOTAL's special processing technologies.
CH72W offers excellent rigidity and impact-resistance in good balance. Additional features include excellent long-term heat-resistance, high resistance to discoloration, antistatic property and dimensional stability.
