Traditional plastic formulations are too brittle to withstand the harsh conditions in industrial applications such as automotive and transportation parts. Plastic parts that are used in extreme conditions must be modified to improve their impact strength and ability to absorb shock.
Plastics play an essential role in the automotive industry due to their ability to withstand engine compartments' high temperatures. Plastics also have excellent resistance to combustion products and solvents. Furthermore, they can be metal plated for the decorative internal components.
The impact strength of polyvinyl chlorides, polyolefins, and engineered resins is typically low or insufficient for the automotive industry at room and sub-zero temperatures. Impact modifying additives are the ideal solution for automotive applications as they improve the impact strength while maintaining the lightweight, design freedom, and easy fabrication that is required by the automotive industry.
