HC plastic mesh News: In the current market can be purchased on a wide range of shoe materials, patterns vary. Soles or shoe manufacturers to determine what their products should meet the performance standards to be standard, and also select materials to: Rubber (RU), thermoplastic rubber (TR), polyurethane (PU) or thermoplastic polyurethane ( TPU ). Upper shoes produced as part of a shoe sole material must be close coordination, therefore, manufacturers should upper material make the right choice. There are design and performance, all of these components must be chosen properly in order to ensure good quality of the final product.

, Of course, shoes and shoes can not be generalized, the requirements of different shoes, especially the soles of the requirements, are not the same. Requirements including the soles of the shoe's light weight, low wear, strong grip, and even Leather Stability, large temperature range, and resistance to chemicals and oil and so on. In general, the market demand shoes is usually above the number required in the combination. All kinds of shoes are important and basic common features such as: walking up the comfort and foot protection. Ironically, the modern, the shoes of these basic features have been gradually replaced by fashion, more and more buyers will purchase the shoe fashion as the most important factor.

For status, material combinations, such as double soles, to be the best, most convenient solution, through the use of resistant outsole to achieve protection of the foot, while using a more flexible midsole to achieve walking comfort. For this purpose, the current combination is the best material to use rubber (synthetic rubber) production of outer end of the end use of polyurethane production. Tread outsole and midsole of the production process can be carried out step by step, and finally to use adhesive bonding them together, in most cases, the need for pretreatment, such as halogenated rubber surface and / or grinding treatment. Another way to bond between the two materials used in auto-adhesive spray technology, the use of rubber chemical bonding functions and features PU adhesive, to achieve the purpose of bonding.

There is a more simple Footwear Material composition is thermoplastic polyurethane and polyurethane, which, with outer soles of shoes produced using the thin layer of thermoplastic polyurethane, used in polyurethane production base.

Addition to their outstanding physical characteristics with the outside, made of thermoplastic polyurethane outer soles of shoes to meet the needs of modern design, making a direct molding process, the produce bright transparent soles or soles.

In addition, carving style, almost without any constraints imposed on the designer's head, even with the characteristics of multi-color shoes soles made in the production process can be quite Economy Sex.

Last but not least is the double soles started to polyurethane / polyurethane material combinations used in production of double-sole, in which two layers of polyurethane soles are made. External end, it must use the special compact polyurethane material, and for the sole interlayer, the consideration for comfort, polyurethane foam must be selected. DESMA

With new technology, shoe-making equipment to ensure that a single mechanical system in industrial rubber, thermoplastic polyurethane and polyurethane activity
