The aromatic structure of ForTii combined with our unique C4 chemistry results in a polymer with a very high melting point of 325°C, complete with high stiffness across a wide temperature range. This in turn makes the heat distortion temperature for ForTii grades among the best in the industry.
ForTii can replace metal at just 50% of the weight over a wide range of temperatures with no compromise on performance. With the highest stiffness to density ratio at elevated temperatures, ForTii Ace brings the most critical metal replacement opportunities within reach.
PPA is already a well-known material in metal replacement. The base chemistry of our ForTii MX series adds additional performance vs. standard PPAs at temperatures above Tg. If you need best in class mechanical performance, the ForTii Ace MX series, with superior mechanical performance and chemical resistance, is what you are looking for.
Vs. PA6 & PA66
PA6 and PA66 are versatile materials for metal replacement opportunities. When mechanics at elevated temperatures (up to 150°C) are needed or the influence of moisture at moderate temperatures should be limited, DSM’s PPA ForTii portfolio meets both challenges. ForTii Ace with a Tg of 160°C, gives superior mechanical performance even after conditioning, for example 85%RH at 85°C. This enables engineers to realize new metal replacement opportunities are not possible with PA6, PA66 or standard PPA.
