Successful Development Of Modified Polypropylene Shoe Materials

　　 Successful development of modified polypropylene shoe materials

It is reported that an enterprise developed " Medium sole material for modified polypropylene foaming shoes New product development projects were identified. Experts from Xiamen University, Fuzhou University, Huaqiao University, Fujian Chemical Research Institute and testing institutions, Gao Gong and other experts are conducting on-site inspection and appraisal. The expert group listened to the report of the project and reviewed the relevant information. After the discussion of the members of the panel, the project was approved and the following comments were put forward:

1, the technical data provided are complete and meet the requirements of appraisal.

2, the product uses block copolymerization polypropylene as raw material to produce sports sole materials for the first time in China.

3, the product has good resilience and compression deformation performance, and comprehensive performance indicators are leading in China.

4. The production process and equipment similar to that produced by EVA foam bottom production can be produced without increasing a large amount of investment and can be put into production.

5, it is recommended to increase market promotion efforts, improve product lines, and promote upgrading. Gym shoes Industrial development.

The middle sole material of modified polypropylene foam shoes is a new high elastic foaming material. It uses block copolymer polypropylene as the main raw material and is processed by a series of chemical and physical methods.

At present, the main soles used in China are TPR (thermoplastic elastomer), EVA, rubber, polyurethane and so on. Among them, the middle bottom material mainly uses the foaming EVA (ethylene vinyl acetate), its material has the quality soft soft and so on. At present, it is widely used by many domestic manufacturers in the fields of sneakers, casual shoes, make-up shoes and slippers. However, such products are prone to deformation when they are dressed, difficult to recover and reuse materials, and lack of resilience.

The modified polypropylene foam shoe material is a new type of shoe material specially developed for the defects of EVA midsole materials. Compared with EVA material, it has better resilience and more comfortable wearing. Foreign countries are mainly used to produce food packaging materials, shock absorbing materials, construction and decoration materials, etc. the EU will also give green labels to food packaging materials produced from polypropylene raw materials.

At present, the polypropylene foam materials developed by the company have been mass-produced and have been applied to some famous brands in the world. According to the measured data of the manufactured products and the data of some well-known brands, the new product has some innovative advantages:

1. The compression deformation index of the new product is better than that of the famous brand products at home and abroad, which has good wear resistance and deformation resistance.

2, there are indicators, the new product in order to reflect its good resilience, especially increased the resilience rate assessment index, according to the measured NIKE sports shoes sample rebound rate is 38%, the new product's measured rebound rate is 42%, the new product has excellent resilience performance.

3. The measured breaking elongation and trouser tearing of the product have reached the standards of famous brand products abroad. Conclusion: the new product has better performance than domestic and overseas brand EVA sneakers.

The success of the new product adds an optional material to the sports shoes industry. And through the test of some technical indicators and comprehensive benefits, the product has the potential to replace EVA medium material. The company is committed to shoe materials especially. Sole The development and production of materials and the development of modified polypropylene shoe materials will set off a new blue ocean for the sole industry of sports shoes.
