Plastics are essential as electrical insulators, making them ideal for high-voltage battery applications where resistance to short-term high temperatures from arc events is crucial. Envalior provides a diverse range of customized plastics engineered to meet these rigorous demands.
Flame-retardant PBTs and PBT blends are preferred for dimensionally critical components like pouch cell frames and round cell carriers. For overmolded busbars, PA6 or PA66 with varied glass fiber content and FR additives are employed to withstand thermal shock. Thermally conductive grades further enhance performance by promoting even temperature distribution and reducing peak temperatures in sensitive components.
