High energy return foam compositions having improved abrasion resistance and uses thereof

This invention describes a special foam designed for shoe parts, particularly the midsole. It's made from a specific type of rubbery plastic that's been partially hydrogenated and then foamed and crosslinked. The claims specify precise ratios for the components of this rubbery plastic to achieve high energy return and improved durability.

Why it matters: Filed before advanced computational chemistry and materials simulation tools became more widely accessible. These tools could now accelerate the optimization of the specific copolymer ratios and processing parameters for this specialized foam.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPolymer chemistry, injection molding, compression molding equipment
