PPE Weathers Heat and Humidity Better than PA

Sabic has introduced Noryl GTX 9500 resin, an addition to its range of unfilled Noryl GTX resin grades that delivers dimensional stability under hot and humid conditions, addressing the challenge for highly demanding automotive applications. The material is a blend of polyamide (PA) and modified polyphenylene ether polymer (PPE) resins. Sabic’s Noryl GTX 9500 resin reportedly retains a better balance of mechanical properties when exposed to heat and humidity typical of automotive under-hood environments than polyamide (PA) 66 and 6 resins. It also has comparable high flow and high-temperature performance, according to Sabic. The material’s dimensional stability and mechanical property retention under a range of temperatures and humidity — together with high flow performance — can open opportunities for thin-wall designs that reduce weight.
