High Impact Talc-Reinforced Polypropylene

Polifil® RMT series compounds are high impact polypropylenes reinforced with asbestos-free talc. In addition to high impact strength, they possess a high flex modulus and high heat deflection resistance. Polifil® RMT products are UL94 HB rated. These compounds are used in automotive applications and conform to the requirements of the FMVSS-302....
