High-temperature polyamide grade offers lightweighting option for blowmolded air ducts


A heat-stabilized blowmolding grade of Stanyl polyamide (PA) 4.6 from DSM Engineering Plastics (Singapore) has been developed specifically for vehicle hot charge air ducts. Components molded from Stanyl Diablo OCD 2305 BM are lighter than current solutions in metal or polyphenylene sulfide (PPS) and can handle continuous temperature up to 230°C.

The new grade is reportedly the first high-temperature PA suitable for processing by extrusion blowmolding and with a significant cost benefit compared to PPS, thanks to its lower weight and scrap rate.
