PARALOID™ Performance Additives for Automotive Applications
Traditional plastic formulations are too brittle to withstand the harsh conditions in applications for automotive and transportation parts. Plastic parts used in extreme conditions must be modified with polymer additives to improve their impact strength and ability to absorb shock.
Thermoplastic formulations play an essential role in the automotive industry due to their ability to withstand engine compartments' high temperatures and their inherent lightweight nature. Plastics also have outstanding resistance to combustion products and solvents. Furthermore, they can be metal plated for decorative internal components of the vehicle.
The impact strength of polymer systems such as polyvinyl chlorides and engineered resins is typically low or insufficient for what the automotive industry demands room and sub-zero temperatures. Impact modifier additives are not only necessary but are ideal for automotive applications as they improve the impact strength of the polymer resin while maintaining the lightweight, mechanical properties, design freedom, and easy fabrication required by the automotive industry.
Dow Chemical Company's Paraloid™ portfolio of impact modifiers and processing aids (PPA) improves the strength and processability of polymer resins and plastic alloys.
