WHY POLYURETHANE SUSPENSION BUSHINGS?
Polyurethane has been with us as a specialized plastic for over thirty years. However, recent advances have now made it possible to engineer very special properties into this exciting material. Suspension bushings are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication.
With the technological advances in this material it has been possible to overcome the common problem associated with harder bushings which is increased noise. By correctly engineering the polyurethane compound, bushings can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties. POWERFLEX bushings make sense.
