Rhodia Engineering Plastics (Lyon, France) has debuted a heat performance grade of Technyl polyamide 66 resin specifically engineered for blowmolded parts for turbocharged engines.

Following on from diesel engines, turbocharging is now considered in Europe a critical technology for powertrain development for today's downsized petrol engines where performance and power output must be guaranteed.

Technyl A 548B2 V15 is the new grade for 2D and 3D blowmolding which allows complex tubular parts capable of resisting temperatures of up to 210°C. This complements Rhodia's Technyl offerings for turbo systems which includes the Technyl Heat Performance (HP) range of products for injection molded applications displaying continuous temperature resistance of 200°C.

"In addition to its high temperature resistance, the new generation of Technyl grades for turbo applications offers excellent processability and cost-competitiveness," comments Manuel Rossi, innovation to market leader for Rhodia Engineering Plastics. "This undoubtedly makes it the best technical and economic compromise for Tier 1s to meet OEMs' growing challenges of higher and tougher heat environments." Ideal for turbo intercoolers and air duct systems, the Technyl heat performance range reportedly broadens the field for PA in automotive underhood applications. —[email protected]
