PBT B4500FC 德国巴斯夫 食品级 型材管材

pbt object performance:

the pbt was milky white or light yellow, tasteless and had adensity of 1.31g/cm3, and the pbt density was 1.53 g/cm3 when 30%glass fiber was added. pbt has good impact toughness, glass fiberreinforced, its various mechanical properties multiplied, under thesame conditions than pom, pc, ppo strength is better. but the notchimpact strength is poor and the glass fiber is strengthened. themechanical properties of pbt decrease with the increase oftemperature, but still maintain high strength at highertemperature. it has excellent creep resistance at differenttemperatures, and hardly changes with the stress time. the fatigueresistance of pbt is better than that of pa and pc
