ForTii Ace Polyphthalamide
Game Changer in Metal Replacement
At K 2016 Royal DSM launched ForTii Ace next generation high performance polyamides. With this new polymer DSM is making a major move to substitution of die-cast metals and expensive high performance engineering thermoplastics like PEEK.
Automotive OEMs are expected to take around 200 kg on average out of every car they make by 2025, in order to meet increasingly stringent CO2 emission norms in major automotive markets around the world. DSM is convinced that ForTii Ace will have an important role in helping OEMs and their component and systems suppliers meet these CO2 targets. 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.
ForTii Ace has a glass transition temperature—the point at which amorphous areas of a material begin to lose their rigidity and hardness—of 160°C, which is significantly higher than other polyphthalamides (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. Most thermoplastics aimed at automotive die-cast metal replacement exhibit a significant drop in mechanical performance when operating at temperatures over 125°C, which is not the case for ForTii Ace, according to the manufacturer. With its high glass transition temperature and high crystallinity, the mechanical performance and the heat-aging performance of ForTii Ace are superior to rival polyphthalamides based on polyamides 6T, 9T and 10T.
With their extreme chemical resistance as well as mechanical performance, some grades of ForTii Ace will even provide cost-effective alternatives to polyetheretherketone, PEEK, in selected applications. The ForTii Ace family will include grades with various types of fillers and reinforcements, including glass and carbon fibers at addition rates of up to 50%.
