Bayer Polymers (www.bayerpolymers.com) has introduced a new heat-resistant thermoplastic for auto -body panels. Called Triax TP 3161, this PA/ABS has a heat distortion temperature of up to 392 F, so it can withstand e-coat process without a conductive primer. The material has also been designed to offer a higher stiffness and lower CLTE than earlier body panel thermoplastics. Triax 3161 targets fender applications, though it could also see use in rear side panels.
