GL-70 TPE Thermoplastic Elastomer is a thermoplastic elastomer composite material developed and produced by YIYUAN, designed for midsole foaming applications. It uses ethylene-based block copolymers as the base material, with excellent rebound performance, ultra-light texture and processing convenience. GL-70 TPE Thermoplastic Elastomer has been widely used in the manufacture of small foam midsoles. It can be efficiently produced through general EVA foaming processing methods and is suitable for mid-to-high-end footwear products that require light weight, high elasticity and high support.
The product is supplied in the form of granules, which is convenient for molding using various types of automated or semi-automated equipment. It is an ideal choice for sports shoes, casual shoes and functional sole materials.

Conclusion：
GL-70 High Rebound TPE Thermoplastic Elastomer has a low specific gravity of only 0.88, which can effectively reduce the overall weight of the sole. At the same time, its elongation of up to 650% and tensile strength of 65 kg/cm² ensure that the finished sole still maintains excellent elasticity and lasting support during high-frequency sports.
This product is designed for small foaming and is still easy to control under high-rate foaming, ensuring uniform pores and stable structure. It can seamlessly replace traditional EVA materials and adapt to existing EVA foaming production lines without major equipment adjustments.
Shore A hardness of 90 provides good support
300% modulus is only 25 kg/cm², soft and firm, comfortable and non-slumping
Tear strength is as high as 25 kg/cm, improving the overall durability of the sole
GL-70 Thermoplastic Elastomer is supplied in granules, which can be recycled and reused, in line with the trend of sustainable manufacturing, easy to measure, transport and automatically feed, compatible with mainstream thermoplastic elastomer processing technology, and suitable for batch continuous production.
Application Scenarios:
Midsole foaming materials (sports shoes, casual shoes, outdoor shoes, etc.)
High-elastic cushion and support structure
Other molded parts that require both lightness and elasticity
Molding Processing Technology
Material Drying:
Store under normal dry storage conditions and avoid direct sunlight.
Molding Method:
The following are some of our processing suggestions and guidelines for foam molding, but in actual operation, past processing experience should be used as the main basis.
Generally, 100% can be added for midsole foaming, and EVA or POE can be added at will according to customer requirements.
Others:
Compression molding conditions are about 70 seconds at 170℃ and 1 mm thick

Dongguan Yiyuan Polymer Materials Co., Ltd. is a company that integrates R&D, production, processing, sales of polymer plastic elastomer materials, plastic modified raw materials, plastic products, and sales of other chemical products (excluding hazardous chemicals): import and export of goods or technology (except for goods and technology import and export prohibited by the state or involving administrative approval).
The company is deeply engaged in professional fields, customer-oriented, and is committed to the modification and solution provision of rubber and plastic raw materials. It advocates reducing the burden on the earth and promoting the recycling of environmentally friendly new materials. Yiyuan provides customers with raw material application technology services, including raw material testing, formula design, product testing, and solving problems in the raw material application process.
Since its establishment, it has invested in the construction of a technical research and development system and established a testing and analysis laboratory. It has independently developed functional materials such as high-elastic particles, lightweight high-elastic particles, ethylene elastomers, thermoplastic elastomers, spot removers, wear resistant agents, shock-absorbing masterbatches, shrinkage stoppers, GRS certified materials, and bio-based certified materials.
Wear-resistant agent is a kind of polymer material made by blending EVA as carrier, silicone coupling agent as main component and active agent. It can reduce the wear of rubber and plastic materials. It will not affect the light resistance, weather resistance, ozone resistance and other physical properties of rubber and plastic materials. Wear-resistant agent is most suitable for TPR, PCU (PVC physical foaming), EVA foaming and other foaming materials.
