GENTREX TK-927

The manufacturing process of the insole of footwear is commonly chemical foaming, where the materials are unrecyclable, and the process will produce greenhouse gases including carbon dioxide and methane, where the final products cannot be recycled for reuse. This product applied the supercritical physical foaming technique, where nitrogen is compressed to supercritical fluid to blend with the melted plastic materials, and after being injected into the mold, the phase transition is utilized to produce the gaps, allowing the finished products to accomplish diversified buffering and bouncing effects, and the products will be completed once cooled and removed from the mold. The raw materials used in the manufacturing process are completely recyclable and reusable, such that no impact will be caused to the environment even if the nitrogen of the foaming raw material is returned to nature. This product is devoted to the application of innovative and mature technologies to solve the pollution issues of conventional manufacturing procedures, while decreasing the carbon footprint throughout the process, making it a brand new proposal for net zero carbon emission for shoe sole industry.
