in the shoe bottom I think I don't say a lot of people will know that it is in the PHYLON bottom, and EVA in common. In fact in the two bottom belong to the same property category (namely Engineering plastics class) , but why have the different name? PHYLON originated in the United States, early in the shoe bottom are called PHYLON, not in the EVA bottom and bottom in the PHYLON, then with the development of the footwear products, in Taiwan and South Korea, some of the big brand footwear factory source for product research and development, in the end of the name of the points more systematic, bottom have what we call EVA. Let me in the popular talk about EVA and PHYLON between different. Shoes bottom with more now is bottom of PHYLON, PHYLON features light, good elasticity, has the very good cushioning properties, PHYLON is called the secondary foam. The EVA bottom is very light, but the cushioning properties and elastic far than the PHYLON bottom, cost is much lower than the PHYLON, EVA in the bottom is called a foaming. They attribute, the name is different, the performance of different reason lies in the PHYLON are secondary foam, EVA is a foaming. ( 1) A foam ( EVA) : after the material injection mould by high temperature after heating a molding shoes in the bottom, is called a foam in the bottom, bottom of the EVA shoes. ( 2) The secondary foam ( PHYLON) : after the material injection mold, by high temperature after heating fire twice molding shoes in the bottom, is called the secondary foam in the bottom, namely we often say the PHYLON bottom. PHYLON hardness is controlled by temperature, in the process of fire in the PHYLON bottom, the higher the temperature, the greater the density of burn-out PHYLON, will be hard. Temperature, the smaller the natural burn-out PHYLON is the lighter the soft, so the stand or fall of evaluation in the shoe bottom can't measured in weight or is the degree of hardness and softness. Different secondary soaked process, the hardness of PHYLON will also vary. ( 1] ( 3) Bales cloth burned in the bottom: cloth burned in the bottom and a bottom of PHYLON, but the design feeling of the whole of the designer in order to pursue a shoe-making technology, a good example of this is, shoe soles and shoe body with the same kind of fabric, the combination of the whole, makes the shoe body and soles is also a bright spot on the shoes production process. Implement the process is wrapped in selected fabrics, established the PHYLON bottom, high temperature in the mould, becomes the LB1 as we see cloth texture of shoes in the bottom.
