ETPU Technology Has Reached The International Advanced Level And Has Filled The Gap In China.

Last month 29, "new high resilience"

The research and development of thermoplastic polyurethane microbubbles (ETPU) has been approved by the China Plastics Processing Industry Association and the China Light Industry Federation. Its overall technology has reached the international advanced level and has filled the domestic blank in Beijing.

It is reported that the project was jointly developed by the Ningbo Institute of materials technology and engineering of the Chinese Academy of Sciences and Jinjiang Guosheng new Mstar Technology Ltd, from the China Plastics Processing Industry Association, the Institute of chemistry, Chinese Academy of Sciences, Sichuan University, Tsinghua University, Beijing University of Chemical Technology, and general post equipment, Ministry of public security, and abroad.

The company's experts constituted an appraisal committee.

In addition, leaders of the China Light Industry Federation, the Fujian provincial science and technology department and the Shanghai national technology pfer center of the Chinese Academy of Sciences also attended the meeting.

　　“新型高回弹鞋材用热塑性聚氨酯微发泡珠粒(ETPU)关键技术研发及产业化”项目采用超临界CO2流体釜压发泡技术和压力补偿新工艺，解决了聚酯型 TPU高温易水解、易黄变的难题，制备出轻质、表面光洁的ETPU发泡珠粒;采用自主研制的模具和水蒸气模压成型技术，生产出环保型ETPU成型体材料，应用于运动鞋的中底、内底和插件等高回弹鞋材领域，产品在弹性模量、拉伸强度、撕裂强度、断裂伸长率、动态能量回馈等方面的性能优于国际同类产品水平，已通过全球着名慢跑鞋Saucony公司和美国着名运动鞋品牌FILA的应用性评价且形成稳定销售;建成国内首条500吨级生产线，实现了8000双/天 ETPU发泡鞋材的生产能力，并获得多项相关发明和实用新型专利。

At the meeting, the expert group listened to the work report, technical research report, inspection, novelty search, user application and evaluation opinions of the project, reviewed relevant identification materials, and some experts inspected the production site of the enterprise before the meeting. After questioning and discussion, the group agreed and agreed that the project results were innovative and advanced, and its technology and products filled the domestic blank, and the overall technology reached the international advanced level.

ETPU shoe material (also known as popcorn sole) has the advantages of excellent performance, high efficiency, environmental protection and melting and recycling. It represents the development direction of flexible foamed materials. Adidas's new product conference in 2013 announced that it is a revolutionary material in the field of shoe materials.

Before the world, only Basf Inc was producing and coordinating.

A strategic agreement to sell ETPU pellets to other sports brands in 5 years is achieved.

The successful cooperation between the Ningbo Institute of materials technology and engineering and the shoemaking enterprises of the Chinese Academy of Sciences has broken through and solved many key technical problems in the industrialization of polyester ETPU shoe materials, and applied high and new technologies with independent intellectual property rights to actual production, greatly enhanced the production technology level of domestic shoe materials and the competitiveness of the international high-end sports shoes market, and created remarkable economic and social benefits.
