ALCOM® PBT 700/8 GF15 PTFE15

1 of 363 products in this brand
MOCOM Compounds ALCOM® PBT 700/8 GF15 PTFE15 is a base polymer composed of polybutylene terephthalate and a filler/additive system of 15% glass fibers and 15% PTFE. It has special features such as improved sliding/wear, high stiffness, good hydrolysis resistance, and heat stabilization. It is typically used in automotive and machinery market segments for functional components, bearings, and sliding elements such as gear wheels and roller bearings. Processing injection molding requires a melt temperature of 250-270°C and a mold temperature of 80-120°C.
