WEB EXCLUSIVE: BASF Corp., Engineering Plastics, Wyandotte, Mich., introduced to North America its Ultramid Endure line of heat-resistant nylons at the North American International Auto Show in Detroit early this month. Ultramid Endure was first introduced at the K 2010 show in Germany. It is a nylon 66 with novel stabilization chemistry that forms a protective surface layer that allows it to retain its high strength in fatigue tests at 220 C for 3000 hr—well beyond the range of other thermoplastics. Aimed at under-hood automotive components, it can even withstand peak exposures to 240 C.
Operating within guidelines from material suppliers can produce levels of polymer degradation. Get around it with better control over either the temperature of the melt or the barrel residence time.
