- Economical two-component injection moulding process
- Cycle time as short as 90 seconds
- Applications: dynamic/static seals and gaskets
To support the growing trend for lightweight automotive construction, Dyneon GmbH and DSM have developed a unique two-component material combination consisting of polyamide and fluoroelastomers. The new material combination opens up new application areas in the entire powertrain.
Economical two-component injection moulding process
The material combination is manufactured using two high-performance materials, Stanyl polyamide 46 from DSM and Fluoroelastomers from Dyneon in an economical two-component injection moulding process. Besides the significantly reduced weight in comparison with the metal components traditionally used, the two-stage manufacturing process provides further economic and environmental advantages.
Cycle time as short as 90 seconds
The cycle time for the process can be as short as 90 seconds. Including the vulcanisation and curing process, the components are ready for installation after just two hours. Moreover, auxiliary chemicals, such as phosphate and solvent based primers, are no longer required, thus eliminating the costs for the purchase and disposal of these.
Applications: dynamic/static seals and gaskets
Both components offer very good mechanical stability, can withstand high temperatures even for extended periods, and are resistant to the chemical impact of aggressive media such as oil and fuels. This makes the material combination suitable for components such as seals and gaskets, both dynamic and static.
Dyneon will be presenting this new development and its product range for the automotive industry at the 2015 DKT/IRC International Rubber Conference and Exhibition.
