DSM launches ForTii Ace next generation high performance polyamides

Royal DSM has launched ForTii Ace, a polyphthalamide (PPA) based on 4T chemistry, that is said to have an outstanding set of mechanical, thermal and chemical properties.

Automotive OEMs are expected to take around 200kg on average out of every car they make by 2025, in order to meet increasingly stringent CO2 emission targets in major automotive markets around the world. Engine downsizing, designing with limited design space, without compromising on safety and comfort are the design challenges of today.

“With ForTii Ace, DSM is taking an important step forward into die-cast metal replacement territory, enabling OEMs to replace metals in applications that have been too challenging up to now,” said Konraad Dullaert, global business manager for ForTii at DSM. “Target applications include powertrain, transmission, chassis, and thermal management applications. At the same time, many industrial applications now incorporating die-cast designs will also benefit from the properties of ForTii Ace as a replacement material.”

DSM is targeting ForTii Ace at die-cast metal replacement applications that require a high mechanical performance that stays constant even at constant-use temperatures as high as 150°C. Such applications may also have design space restrictions and/or NVH (Noise, Vibration, Harshness) challenges.

ForTii Ace has a glass transition temperature of 160°C, which is claimed to be higher than other PPAs, including existing ForTii grades, and at least 80°C higher than PA66. It also has higher resistance to various automotive oils and chemicals, even compared with PEEK.
