tech.day 2022: High-end elastomers for functional applications in BTMS
Zero defects tolerance applies in particularly in high-tech applications involving a high degree of functionality such as tightness, resistance and durability. With precisely these applications in mind, Poly-Nova Technologies, the Canadian enterprise, has developed both a perfectly adapted high-end elastomer and the component itself, manufacturing these to the highest quality standards for its global customers. The specialist supplies around 70% of these 2K thermoplastic or metal components (overmolded with a high-end elastomer) to the automotive industry, but these tailored materials and functional parts are also used in a variety of other industrial and medical applications.
Against the background of more ecologically sustainable energy and transport policies and the EU prohibition of internal combustion engines as of 2035, functional parts for battery thermal management systems (BTMS) in e-vehicles are, in particular, currently greatly in demand. These take on tasks here such as pumping, conveying, check/non-return and sealing applications, and 100% fault-free operation over a long period is vital in this context. The need to be resistant to the thermofluids used, regardless of whether glycol or a dielectric medium is involved. It is also essential that all functional parts of a battery system used remain functional within a broad temperature range, as the battery requires cooling in summer and heating in winter if it is delivery its full capacity.
Poly-Nova has already conducted extensive tests in the R+D centre on direct cooling systems for BTMS and, on the basis of these investigations and the experience gained, now offers appropriate recipes to all interested parties. Physical properties of the material such as the coefficient of friction, abrasion behaviour and thermal conductivity can be optimally adapted in this context. Basic materials such as FKM, FVMQ, HNBR, XNBR, ACM, EPDM or VMQ may be involved. “We are well prepared to meet the growing demand for BTMS and look forward to addressing the individual requirements of our customers”, says Rick Valeriote, inviting both automotive manufacturers and tier 1 to approach Poly-Nova with their specific issues and profit from the expertise it offers.
Speaker:
Rick Valeriote is the founder of Poly-Nova Technologies in Guelph, Canada. Together with Garrett Hutchinson, Manufacturing Engineering Manager at Poly-Nova, the chemist and a team of 150 develop individual, specific elastomers for high-tech applications. Established in 1996, Poly-Nova has been part of the starlim-sterner Group since 2011, perfectly complementing the product spectrum of the liquid silicone specialist. In common with starlim, Poly-Nova not only possess enormous recipe know-how with regard to the elastomers it develops itself, but also extensive production experience, manufacturing components for its global customers on its around 50 fully automated injection molding machines.
