Blending polypropylene grades of Celstran long fiber-reinforced thermoplastics (LFRT) with Topas* COC (cyclic olefin copolymer) reduces warpage for automotive, packaging, medical, optical and other parts by as much as 80 to 90%.The option to use Topas COC as an anti-warp agent in complex parts helps designers and engineers reduce tool corrections and speed time to market, allowing auto manufacturers to make wider use of polypropylene and create parts that are ideal for recycling. Blending Topas COC with other resins and compounds is being explored to enhance performance, reduce warpage, increase temperature resistance, add stiffness and improve electrical characteristics.
