Issue 3/2019 - Age-resistant materials reduce costs and increase efficiency for automotive thermal management systems

DSM (DSM) recently launched the Xytron^®G4080HR, a commercially available engineering plastic product to the automotive industry, achieving the comprehensive goals
of optimizing operating conditions, extending component life, reducing energy consumption, shortening design replacement cycles, improving component versatility and reducing costs for automotive thermal management systems (TMS).

This product facilitates the design flexibility, thinning, and weight reduction of automotive thermal management system components, and makes the long-term performance predictability of the final part easier due to its better aging stability and weld line strength retention, making it possible
for automotive thermal management system components to save costs by reducing wall thickness.

At the same time, the ultra-hydrolysis resistance of Xytron^®G4080HR products provides long-term performance assurance
to meet the material challenges of automotive thermal management system transformation 。 The aging experiment in water-ethylene glycol at 135 °C for 3000 hours proved that the tensile strength and elongation at break of the product showed excellent performance, its tensile strength was only reduced by 21%, the competitor decreased by 61%, and the strength performance after aging was 114% higher than that of the competition.
Elongation at break decreased by only 29%, competitors decreased by 49%, and the actual elongation at break after aging exceeded that of competitors by 63%.
