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.

　　“新型高回彈鞋材用熱塑性聚氨酯微發(fā)泡珠粒(ETPU)關(guān)鍵技術(shù)研發(fā)及產(chǎn)業(yè)化”項(xiàng)目采用超臨界CO2流體釜壓發(fā)泡技術(shù)和壓力補(bǔ)償新工藝，解決了聚酯型 TPU高溫易水解、易黃變的難題，制備出輕質(zhì)、表面光潔的ETPU發(fā)泡珠粒;采用自主研制的模具和水蒸氣模壓成型技術(shù)，生產(chǎn)出環(huán)保型ETPU成型體材料，應(yīng)用于運(yùn)動鞋的中底、內(nèi)底和插件等高回彈鞋材領(lǐng)域，產(chǎn)品在彈性模量、拉伸強(qiáng)度、撕裂強(qiáng)度、斷裂伸長率、動態(tài)能量回饋等方面的性能優(yōu)于國際同類產(chǎn)品水平，已通過全球著名慢跑鞋Saucony公司和美國著名運(yùn)動鞋品牌FILA的應(yīng)用性評價(jià)且形成穩(wěn)定銷售;建成國內(nèi)首條500噸級生產(chǎn)線，實(shí)現(xiàn)了8000雙/天 ETPU發(fā)泡鞋材的生產(chǎn)能力，并獲得多項(xiàng)相關(guān)發(fā)明和實(shí)用新型專利。

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.
