Trapylen® 145 X 5 is a chemically modified low-chlorinated polypropylene renowned for its remarkable affinity to polyolefinic plastics, including PP, PP/EPDM-blends, and, with certain limitations in adhesion strength, PE. The resin in Trapylen® 145 X 5 is characterized by a higher molecular weight within the range of 110,000 and a significantly lower chlorine content compared to other maleic-modified Trapylen® grades. These specific properties contribute to improved adhesion, as well as enhanced heat and chemical resistance. It is primarily utilized as a straight primer, with its principal application in the treatment of molded parts and sealing profiles in the automotive industry, including bumpers, side panels, and door seals.
