The thermoplastic Jounce Bumper is designed by DuPont Performance Polymers to replace incumbent foam polyurethane (PUR). Jounce Bumper is a part on the top of the suspension to prevent shock at the end of the metal spring compression and improve vehicle behaviour.
The Jounce Bumper – an additional spring used in car shock absorbers to improve vehicle behaviour and comfort even in demanding conditions – is made from DuPont™ Hytrel® TPC-ET and offers many benefits over existing PU-based alternatives. By collaborating with OEMs through design, material selection and processing, DuPont has developed a patented blow moulding process that ensures optimum energy absorption. Working closely with OEMs using non-linear Finite Element Analysis (FEA) software and the Expert System from DuPont, the design of the Hytrel® Jounce Bumper can be optimised to meet static and dynamic requirements of the OEM.
The new office chair – the Generation from Knoll® – is made using a renewably sourced polymer from DuPont. Key to the chair’s flexing and supportive features is the use of the DuPont™ Hytrel® RS Renewably Sourced thermoplastic elastomers and DuPont™ Crastin® PBT for the Flex Back and the Dynamic Suspension control.
Other sustainable products include DuPont™ Zytel® 66 Halogen free* which can withstand extremely high continuous temperatures thanks to a new heat stabilisation technology, and a broad range of DuPont™ Zytel® HTN halogen-free* nylons able to fulfil the most demanding applications such as Surface Mounted Devices (SMD) components and Hand Held Device (HHD) and the recently launched impact-modified, low-emission DuPont™ Delrin® 300TE, which extends the scope of application of POM into multiple applications, including those in automotive interiors, where resistance to high impact loads is required.
Visitors will also be able to see DuPont™ Vamac® Ultra HT, a new grade of ethylene acrylic elastomer (AEM) that extends the Vamac Ultra family of high-performance elastomers, offering enhanced continuous heat resistance up to 180°C, with peaks to 200°C.
Where performance really matters... whether you are looking to save costs or looking for a better sustainable alternative, DuPont can help – calling upon its extensive global capabilities in application development, polymer technology and innovation.
