DSM’s Stanyl ForTii used in exhaust gas recirculation temperature sensors
EGRT sensors are critical elements to improve overall vehicle performance, monitor emissions and improve fuel efficiency.
Stanyl ForTii, thanks to its ability to withstand continuous-service temperatures up to 300°C, allows significant cost savings, without sacrificing thermal or structural performance. Alternative materials for EGRT sensors include liquid crystal polymer (LCP) and polyetheretherketone (PEEK), both of which are more expensive.
In close cooperation with its customers, DSM’s application development team identified the operational parameters for the EGRT application. Extensive prototype testing demonstrated that Stanyl ForTii has the thermal performance and mechanical properties required for the demanding environment in which the sensor operates.
With the appropriate design, Stanyl ForTii can withstand a temperature as high as 325°C on an intermittent basis and still retain all the mechanical properties required for this very demanding application. It also has the excellent chemical resistance necessary.
“Stanyl ForTii is not only significantly more cost-effective than PEEK in this application, it also offers shorter molding cycle times than other alternative high performance engineering plastics,” says Chris Scarazzo, Business Development Manager at DSM. “Until now, LCP and PEEK have been the default high temperature materials of choice for applications like this. Now, Stanyl ForTii will enable design engineers to specify a more economical material for very hot and aggressive environments.”
Stanyl ForTii is making an important contribution to keeping the air clean, cost-effectively. The application is firmly in line with DSM’s ‘Bright Science. Brighter Living’ philosophy, which is geared towards creating sustainable shared value for all its stakeholders based on innovations that benefit people, planet and profit.
DSM’s engineering plastics portfolio supports automotive suppliers meet the demanding needs of both technical performance and cost targets in for example the automotive, electrical and electronics markets.
In addition to innovative materials such as Stanyl ForTii that have outstanding mechanical properties that are retained across a broad temperature range, DSM’s portfolio also includes engineering plastics derived in large part from renewable resources, further adding to sustainability all along the supply chain.
