For automotive cooling system applications, hydrolysis stabilized plastics have been preferred for many years due to their light weight and improved hydrolysis performance compared to metals. With electric vehicles increasing their share in the industry every day, the impact of thermal management systems on battery performance has also become more important. In this regard, the automotive industry has intensified its efforts on both traditional hydrolysis stabilized products and alternative products. Demand for the use of Polypropylene (PP)-based products in such systems is increasing, both due to the lower heat exposure in electric vehicles than in internal combustion vehicles, and in the context of sustainability and cost.
eurotec® has conducted long-term tests to investigate the hydrolysis performance of glass fiber reinforced PP products for critical components in cooling systems such as connectors. Tecolen® HP10 GR35 NL HT A (PPHP, 35% glass fiber reinforced, hydrolysis stabilized, natural) maintained its tensile strength and % elongation values at the end of the test performed in an ethylene-glycol/water (50:50) mixture for 2000 hours at 120°C (Chart 1).
