For example, these adhesives are used in the automotive industry, in both interior and exterior applications such as car body assembly, synthetic leather door panels, and center consoles. Polypropylene (PP) is also commonly used as an important material due to its useful properties, including high chemical resistance and good heat resistance, as well as low specific gravity. In fact, PP is the most consumed engineering plastic for interior vehicle parts, finding applications in dashboards, door panels, sidewalls, roof linings, center consoles, break and accelerator pedals, and air bags. As a result, PP contributes to the reduction of car body weight and raw materials costs.
