Foam compositions and uses thereof

This invention describes a special foam designed for shoe components, particularly midsoles. The foam is created by processing a specific type of plastic material, a partially hydrogenated thermoplastic elastomeric block copolymer, through crosslinking and foaming. The goal is to produce a foam that offers high energy return, durability, and softness for footwear.

Why it matters: Given the short three-year gap, no fundamental enabling changes in polymer chemistry or industrial foaming techniques are evident. The primary challenge likely remains in precisely formulating and cost-effectively scaling this specific block copolymer foam for mass production.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedChemical formulation, industrial foaming, molding equipment
