AUTOMOTIVE OEM V E H I C L E L I G H T H E A T S I N K S • Replace aluminium to reduce part weight and cost • Excellent thermal performance • Simplify manufacturing process • Reduced part weight by 40% and 44% in two heat sink designs while matching the performance of the incumbent material • Met thermal efficiency demands through part re-design and material selection support • Customized multiple formulations to satisfy customer needs • Improved manufacturability by changing to a single injection molding step Therma-Tech™ Thermally Conductive Formulations KEY REQUIREMENTS WHY AVIENT?

Silicone’s excellent resistance to staining, however, comes with some trade offs - limited design freedom, long lead times and supply chain challenges. Increase design freedom – Our material enables enhanced design freedom through overmold adhesion to common polycarbonate substrates. Increase speed to market – Avient TPEs have a shorter lead time than silicone and can be processed quickly on high speed injection molding equipment.

The use of 2K (two-component) molding—in which the base resin is injected and allowed to set up for a short time, and then is overmolded by injecting the TPE—streamlines the manufacturing process. It required a high temperature and a strong injection pressure to bond to the acrylonitrile- butadienestyrene (ABS) substrate, which caused the resin to deform. High-end product line = competitive advantage: With Avient’s OnFlex-S TPE, developers successfully designed and produced a new, high-end product line that compares favorably with all-plastic sprayers in terms of appearance, performance and durability
