TPU Vacuum Forming Film for PU Shoe Sole

TPU vacuum forming film is a sheet or roll high-performance film material made from thermoplastic polyurethane. TPU vacuum forming film is bonded to PU shoe sole components via vacuum adsorption, being durable, flexible, comfortable, and color-coordinated PU shoe soles. TPU vacuum film produced by casting process boasts a high degree of surface smoothness, uniform thickness, excellent transparency, and stable performance, is an ideal film material for high-end footwear.

Production Introduction

TPU vacuum forming film is wear-resistant, oil-resistant, slip-resistant, and features attractive patterns. TPU vacuum forming can be manufactured in the same mold with the PU sole, without glue, environmentally friendly and odorless, which creating a perfect combination for sole manufacturing.

 Compared to traditional PU shoe soles, TPU vacuum forming film improves the hydrolysis，enhances the appearance and solves the porosity problem. The customized TPU film patterns, resulting in a more colorful and vibrant look. TPU vacuum forming film combinations with PU shoe sole,  without painting and printing spraying, be environmentally friendly .

Production Parameter

TPU vacuum forming film is a polymer material between rubber and plastic, whose unique molecular structure makes PU shoe soles three core advantages.

1.     Elastic memory

Rebound rate of over 85% after compression

2.     Abrasion resistance

 3-5 times more abrasion resistant than ordinary rubber

3.     Temperature adaptability

 Maintains stable performance from -30℃ to 80℃

The vacuum-sealed process of TPU vacuum forming film is an advanced technology in PU shoe sole production, being 3D structure through vacuum adsorption.
