ETPU popcorn soles represent a new-type material formed by foaming and processing TPU materials. The elastomeric particles feature tiny closed cells, similar in size to common popcorn, hence the name "popcorn material". Soles shaped from this material are the popular popcorn soles, which first caused a sensation when Adidas launched them into the market. They were immediately sought after by football stars and later beloved by the public. Popcorn soles not only exhibit extremely high wear resistance compared to traditional sole materials but also offer far greater elasticity than common PU and EVA.

Sports shoes and casual shoes with popcorn soles can significantly protect feet during activities like walking, running, mountain climbing, and other sports. Their high rebound property reduces physical exertion, and professional scientific tests have proven that ETPU popcorn soles also demonstrate excellent folding resistance. Currently, ETPU no longer relies on imports and has reached maturity in development. It is widely applied not only in sole manufacturing but also in other market sectors such as floor mats, helmets, and decorative packaging. After its basic environmental friendliness gained recognition, manufacturers are attracted to this material for its diverse advantages.

ETPU is environmentally friendly throughout both production and use, recyclable, and boasts excellent performance. It easily adheres to and integrates with other materials, resists permanent deformation after repeated use, and exhibits strong anti-aging properties. It is believed that ETPU will be adopted in products across numerous market sectors in the future.
