<p>A resilient pad for keyboards, such as computer keyboards, is disclosed. The pad is composed of EPDM blended with a copolymer of propylene oxide and allyl glycidyl ether. Each of the polymers is present in the amount of 10-90 parts. An accelerator system for the polymer blend is also disclosed. The pad has substantially improved resilience as measured by the hysteresis of the pad.</p> |
