Abstract
Rubber in its uncured state is very tacky and rubber forms such as pellets, sheets, etc., tend to be hard to process due to the agglomeration and sticking of these rubber forms. Aspects of the invention use cured rubber powder as an anti-tack agent in a molding rubber mixture. In one aspect, the cured rubber powder has a particle size between 50 and 250 μm in the uncured rubber forms, a diameter of between 1 and 10 mm, and a length of between 1 and 15 mm.
