A family of vibration and shock-isolation thermoplastic rubber (TPR) materials from E-A-R Specialty Composites, Indianapolis, have formulations which can be adjusted to optimize both damping performance and durometer. The VersaDamp 2000 Series feature durometers ranging from 35 to 75 Shore A, and contain no sulfur, carbon, or plasticizer. The materials are injection-molded into isolators and other equipment components. They are suitable as antishock and antivibration mounts for small devices with limited isolator sway space, such as pagers, cellular phones, laptop, and handheld computers. Other applications include those with wide-ranging operating temperatures such as small motors, fans, and electrical relay boxes in vehicles.
