Natural rubber price knowledge

Polyurethane (PU) The simplest shoes are made from single density polyurethane outsole. Polyurethane sole must have two tasks: first, we must feel comfortable, and light sole, and second, it is also very important point, that is, safety issues, such as non-slip. In fact, it's hard to put the two functions together, and in most cases only one of them will perform correctly. The density of polyurethane soles are mostly around 0.8g / cm3, usually used for casual shoes. The production of single density shoes is very simple and effective, but the products produced are still high-end commercial shoes. Polyurethane / Polyurethane (PU / PU)


For more than 20 years, the direct injection molding machine has been used in the footwear industry to produce double density polyurethane shoes. The combination of a dense polyurethane outsole and a lightweight and comfortable midsole makes it possible to combine two characteristics in one shoe. The outsole can be made from a very densely packed material, giving it greater resistance to abrasion and good slip and grease resistance. Foam polyurethane systems can be used to make the midsole so that the shoes wear more comfortable and even lighter.


   The production of shoes and single density shoes processing different, the first step, the need for a dense outsole into the closed mold. After a certain period of reaction, the upper midsole and outsole injection molding, through the soles and the upper bonding, a simple shoe sample that succeeded. In most cases, this combination of materials is used in the safety footwear industry, because in this industry it is important to look for a comfortable look as well as good features. However, in casual footwear, there are many interesting designs that use polyurethane / polyurethane combinations. Density The density of the outsole is mainly 0.9g / cm3, while the density of the midsole is mostly 0.45g / cm3. For safety shoes, the two layers of adhesive exceed the required standard, the midsole can be made with a thinner layer.


  Thermoplastic Polyurethane (TPU) This combination of materials is not as advertised because the single-density thermoplastic polyurethane outsole will not make shoes comfortable to wear, the density of thermoplastic polyurethane around 1g / cm3, which means that this Footwear on the foot of the class can not produce good sound insulation. In addition, the thermoplastic polyurethane is often very difficult to adhere to the upper, therefore, thermoplastic polyurethane outsole is not often used.
