A method of forming a polymeric foam material is provided and includes providing a precursor material having a first thickness, the precursor material being an open-cell foam material and applying a uniaxial compressive force to the precursor material to compress the precursor material to a second thickness, the compressive force causing a cell structure of the precursor material to collapse. The method also includes heating the precursor material at a molding temperature for a first time period while the compressive force is applied, the first time period being sufficient to heat the precursor material to a softening temperature, removing the compressive force from the precursor material, and maintaining the cell structure of the precursor material in a collapsed state.

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 &#x3bc;m in the uncured rubber forms, a diameter of between 1 and 10 mm, and a length of between 1 and 15 mm.
