Lightweighting and Space-Saving
Without Sacrificing Safety
As the automotive industry shifts towards electric vehicles, there is increasing demand for lightweighting across various components. However, lightweighting and space-saving require a balance with safety performance, including impact resistance and insulation. TUFTEC™ and S.O.E.™ provide excellent impact resistance and flexibility, contributing to solving these challenges.
Balancing Lightweighting and Impact Resistance with TUFTEC™
In the automotive industry, as EV adoption accelerates, lightweighting is crucial for improving fuel efficiency. This involves replacing metal parts with plastic, as well as exploring thinner wall thicknesses, foaming, and other methods for reducing the weight of plastic components (e.g., bumpers and door trims). However, thinner wall thicknesses and foaming pose challenges in maintaining or improving impact resistance from a safety perspective.
TUFTEC™ H1062 boasts a low glass transition temperature, making it ideal for low-temperature applications. With TUFTEC™ H1062 as an additive, it's possible to maintain or enhance the impact resistance of components, even after thinning or foaming, ensuring they meet safety standards.
Achieving Thin-Wall Thickness and Insulation in Wire Harness Coverings
Hybrid and electric vehicles operate with high-voltage batteries. As such, wire harnesses require exceptional insulation. Polyvinyl chloride (PVC), commonly used, has limited voltage resistance and necessitates thick Coverings for adequate insulation. This results in increased space and weight requirements, posing a challenge for PVC.
Wire harness Coverings formulated with TUFTEC™ or S.O.E.™ offer superior insulation compared to PVC, even with thinner Coverings. This reduced thickness, combined with enhanced flexibility, contributes to the lightweighting and space-saving of wire harnesses.
Furthermore, S.O.E.™ exhibits excellent compatibility with fillers, allowing for high-fill loadings of flame retardants (fillers) without compromising the coating's hardness. This enables high flame retardant concentrations, enhancing the fire resistance of wire Coverings.
