Polifil® T

Polifil T

Talc-Reinforced Polypropylene

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.

Use this information as a guide to aid you in selecting the proper resin for your application. TPG will custom compound and fine-tune our formulations for your application.


The property values listed in the PDF document(s) have been obtained using laboratory controlled test methods.
