DSM are launching a new resin system designated Daron 220 that is said to help pultrusion companies to make profiles and structures at high speed and with process robustness.
DSM state that this new product can be easily tuned for a variety of applications, used as a single resin or as part of a two-component system, and because of its low viscosity, glass fibre impregnation is straightforward. This allows making components with great strength, both with glass and carbon fibre. DSM says that the parts can demonstrate an excellent heat resistance.
For many years the DSM Daron resin series have claimed to demonstrate superior properties in a variety of end-use markets, including building & infrastructure, transportation and industrial. With the addition of the new resin system the number of applications is extended, while offering composite component manufacturers an increase in process robustness and high production speeds.
When used as part of a two-component system the glass transition temperature of the resin can be as high as 220 °C, way above the glass transition temperature of conventional vinyl ester resins.
The chemistry of Daron 220 enables running pultrusion lines at much higher speed vs. traditional high heat epoxy resins, say DSM. The Daron 220 resin can give excellent properties both with glass and with carbon fibres.
“DSM is known for its innovative power delivering composite solutions that can improve end-user performance”, comments Robert Puyenbroek, Chief Technical Officer of DSM Composite Resins.
“While helping our direct customers to better run their operation, these material systems clearly enable end-customers to more frequently use composites in their markets”.
“Here again, DSM is able to bring a future-proof technology that will allow composites to be used in higher heat applications replacing steel and aluminium”, adds Fons Harbers, European Commercial Director DSM Composite resins. “DSM is committed to lead the industry and introduce new product innovations that push the performance envelope for composites”.
The use of composites within the rail industry is predicted to grow by up to 40% between 2015 and 2020 according to the Composites Leadership Forum, reports Fibrelite, a UK manufacturer of composite trench covers.
Plasan Carbon Composites (PCC) has been awarded a contract to produce the first composite ramps and bridgeplates for Amtrak.
