The latest resin to benefit from of an auto industry-wide shift to increased adoption of turbochargers is a high-heat polyamide (PA) developed by Rhodia Engineering Plastics (Lyon, France), a member of the Solvay group. The Technyl PA grade has been chosen by molder Röchling Automotive for the manufacturing of turbocharger air ducts which have to resist temperatures of up to 210°C.
PA scores once again in turbo application.
The PA 66 blowmolding material—Technyl B2 (grade name: A 548B2 V15 )—is the designated product for turbo systems and has been used by Röchling Automotive for over a year. "Thanks to Röchling Automotive, our polyamide is already utilized in more than 300,000 automobiles, which fully confirms customer benefits and positions Rhodia's Technyl range as a benchmark for turbo air duct systems," says Nicolas Batailley, business development manager, Rhodia Engineering Plastics.
For several years now the automobile industry faces the growing need for smaller yet high-performing turbocharged engines. To meet the increasing material challenges this imposes, Rhodia Engineering Plastics is developing next generation Technyl blowmolding grades to meet even higher underhood operating temperatures.
