ForTii®  MX for metal replacement

The cost-effective alternative for die-cast metal replacement between -35°C and 160°C

ForTii® MX

The polyamide for die-cast metal replacement

If you’re looking to unlock new design potential in automotive applications – boosting performance, cutting fuel emissions and reducing cost of ownership - then ForTii PA4T metal replacement (MX) portfolio is your number one choice. The ForTii MX portfolio contains semiaromatic polyamides, based on DSM’s PA4T technology, enabling you to engineer the incredible, by thinking beyond metal and beyond its traditional alternatives. ForTii is tested extensively in parts, since testing of tensile bars does often not represent the part complexity (ribs, weldines, inserts) in the real world.

ForTii MX grades show better properties than existing PPA materials in terms of mechanical strength and toughness across a broad range of temperatures. Grades are available with glass fiber reinforcement ranging from 15 to 60%. ForTii MX combines best mechanical performance (especially impact strength) in combination with high dimensional stability from -35° up to 160°C with limited influence of moisture.

ForTii MX - No compromises on cooling applications

Modern engine downsizing trends put high demands on automotive systems and its components. DSM’s semi-aromatic polyamide ForTii MX15HR is the perfect solution for automotive cooling components such as thermostat housings, valves and hose barbs. 

The new benchmark in metal replacement of structural parts

ForTii® Ace MX53T enables designers to realize up to 50wt% reduction versus alu die-cast replacement, NVH optimization (damping, stiffness), cost reduction in case of multiple secondary operations (10-30%), or part integration to de-complex the production chain (less steps).

Key features: 

  • Robust part performance from -35°C up to 150°C
  • Excellent chemical resistance
  • Enhanced surface quality
