The Royal DSM Group brings the new polyamide product ForTii® Ace to the 2016 International Plastics and Rubber Fair in Dusseldorf, Germany (2016 K Show). ForTii® Ace is a 4T-based polyphthalamide (PPA) with a series of excellent mechanical, thermal and chemical properties to replace metal die castings and expensive high-performance thermoplastic engineering plastics such as polyether ethers Ketone (PEEK).
ForTii Ace has a glass transition temperature of 160 ° C, which is significantly higher than other polyphthalamide materials, including existing ForTii grades, which are at least 80 ° C higher than PA66. ForTii Ace is even more resistant to various automotive greases and chemicals than PEEK.
According to Konraad Dullaert, global business manager of DSM ForTii, the thermoplastics that currently replace automotive metal die castings on the market are mostly used at temperatures above 125 ° C, and the mechanical properties will be greatly reduced. "And ForTii Ace will not, so this is a huge improvement. With its higher glass transition temperature and crystallinity, ForTii Ace has better mechanical properties and heat aging resistance than those based on polyamide 6T, 9T and 10T. Competitive phthalamide products. ForTii Ace is the only polyphthalamide product with an aromatic compound weight ratio of more than 50%.
Suitable for applications requiring long-term strength under high temperature conditions
Dullaert also said: "ForTii Ace is designed to be used in areas with high requirements for mechanical properties and chemical stability, even when continuously used at 150 ° C, it can maintain stable mechanical properties and replace metal die castings. Such applications may also be Face multiple challenges including limited design space, noise, vibration, and harshness (NVH). "
With its excellent chemical resistance and mechanical properties, certain specifications of ForTii Ace can even be used as a cost-effective alternative to PEEK in specific applications. The ForTii Ace family includes different grades made of different types of fillers and reinforcements, including up to 50% glass and carbon fiber.
It is expected that by 2025, each vehicle produced by the vehicle manufacturer will lose approximately 200 kg to meet the increasingly stringent carbon dioxide emission standards of the world's major automotive markets. DSM is convinced that ForTii Ace will play an important role in helping vehicle manufacturers and their component and system suppliers meet carbon dioxide emissions standards.
