Research on the Impact of Flame Retardant Selection on the Performance of TPO Environmentally Friendly Automotive Interior Materials

Abstract

TPO environmentally friendly automotive interior materials feature low VOCs, recyclability, and excellent mechanical properties,
making them an important development direction in green automotive manufacturing. This paper focuses on the impact of flame retardant
selection on material performance, systematically analyzing the effects of factors such as the chemical structure of flame retardants, system
ratios, and addition methods on the dispersibility, compatibility, odor control, and thermal stability of TPO materials. Using molecular simulation and compound optimization methods, a halogen-free flame retardant system is designed to synergistically improve environmental performance, achieving the goals of automotive interior materials that are safe, low-emission, and energy-efficient in production, thereby laying
the technical foundation for the greening and high-performance development of automotive materials.
