Polifil® PP T-20

About
Polifil ® T series compounds are homopolymer polypropylene resins reinforced with asbestos-free talc. They possess high flex modulus, high deflection temperature, good chemical resistance and colorability, low shrinkage and yield maximum stiffness combined with characteristic impact. Polifil ® T products are UL94 HB rated. These compounds are used in automotive (underhood) applications, major appliances, electrical goods, housewares and other utility products. Standard processing techniques are applicable.&&
