DSM raises the bar again: high temperature resistant polyamides

  • New high temperature resistant polyamide grades
  • Polyamide 46 withstands 230°C (and peaks up to 267°C)
  • DSM at #Fakuma

Royal DSM has launched new high temperature resistant polyamide grades which are part of DSM’s Stanyl polyamide 46 and Akulon 6/66 portfolios and are aimed at applications in automotive engine compartments.

The latest version of Stanyl Diablo polyamide 46 is able to withstand a continuous use temperature of 230°C, while the new Akulon Diablo withstands a 220°C continuous-use temperature. Both new grades have improved resistance to short-term high temperature peaks as measured by deflection temperature under load (HDT). New Stanyl Diablo has an improved HDT of 267°C, while the new Akulon Diablo has an HDT of 245°C. The long term heat ageing and the HDT of the new materials are proof of their superior characteristics compared to competing materials currently on the market. The new grades also have improved resistance to chemicals and gases in EGR (exhaust gas recirculation) systems.

DSM is a leader in the development of high temperature resistant thermoplastics for automotive engines. Only a few months ago the company introduced the world’s first plastic air intake manifold (AIM) with integrated charge air cooler (CAC) made from PA46 that can withstand peaks up to 250°C.
