BounCell-X TPU Foam

BounCell-X™ TPU Foam

Better performance for users and increased manufacturing automation for producers

Recognizing a critical need for a high quality midsole material that benefits both users and manufacturers, Lubrizol Engineered Polymers formulated a unique material made from thermoplastic polyurethane (TPU) chemistry and a unique physical foam injection molding technology with nitrogen gas to form BounCell-X™ -a low density, plasticizer-free, recyclable*, thermoplastic foam that outperforms competing materials in cushioning, compression, and durability.

In addition to numerous physical property benefits, BounCell-X™ provides footwear companies with enhanced performance through sustainable manufacturing. BounCell-X increases automation thereby reducing dependency on manual labor, improving quality, and reducing material scrap. BounCell-X also does not require any pre-treatment application of chemicals, which enhances environmental friendliness, safety and greatly reduces overall production time and complexity.
