In addition to cost-effectiveness, fillers can improve the mechanical properties of plastics. For instance, the addition of glass fibers or carbon black can enhance the tensile strength, impact resistance, and stiffness of polymer composites. This makes fillered plastics suitable for a wide range of applications, from automotive components to electronic housings. In particular, glass fiber-reinforced plastics (GFRP) are increasingly used in lightweight construction, as they combine low weight with high mechanical strength, thus offering improved fuel efficiency in transportation.
