Styrenic thermoplastic elastomers for high-efficiency foams in the automotive industry
This article explores the application of styrenic thermoplastic elastomers(SEBS)as efficient foam materials in the automotive industry.The impetus for the study stems from the automotive industry's demand to reduce vehicle weight in order to lower greenhouse gas emissions.The article experimentally analyzes the impact of SEBS on polypropylene(PP)foam formulations,as well as the effects of different SEBS structures,concentrations,and talc powder concentrations on the mechanical properties of the foam.The research findings indicate that the addition of SEBS can enhance the impact resistance and elasticity of PP foam,improve the flexibility of the foam and reduce its brittleness.Even with a 50%reduction in weight,the foam formulated with SEBS maintains good mechanical and structural properties,contributing to the realization of automotive lightweighting and the reduction of carbon dioxide emissions.
