Should recognize how the PU soles?
PU soles should be one of the most wear-resistant soles.
PU-foam dissolved into a jelly and then poured into the model heating it foam, smooth finished surface, after a long time will turn yellow and corrosion, has a certain shock absorbers and stability.
Shoes in the end I do not think I said that many people will know that is the end PHYLON the most common, and an EVA midsole. Two bottom belong to the same attribute category (plastic type), but why has called on the different? Origin PHYLON in the United States, called PHYLON oldest shoes in the end, and no EVA midsole and PHYLON in the end points, and later with the continuous development of footwear products, brand footwear product development factory in Taiwan and South Korea source, the name of the end points more systematic, there we are talking about EVA midsole. Here I will talk about the difference between EVA midsole and the end PHYLON popular.
The soles of the shoes up to the end PHYLON, PHYLON biggest feature is lightweight, flexible, with good cushioning performance PHYLON called secondary foam. EVA midsole is also very light weight, cushioning and flexibility is far smaller than PHYLON in the end, the cost is much lower than PHYLON, EVA midsole is known as a foam. The reason they attribute the same, but different names, different performance is PHYLON secondary foam, EVA is a foam.
(1) a foam: heated to high temperatures forming a shoe midsole material into the mold, called a foam midsole is EVA shoe midsole.
(2) Secondary Foam: fired after two high-temperature heating material into the mold, forming the shoes in the end. The PHYLON the hardness is controlled by temperature, firing the end PHYLON process, the higher the temperature the greater the density of the burning of PHYLON, the more hard. Heat the smaller the natural burning of PHYLON the more light the more soft, so the evaluation of the shoes in the end good or bad can not be by weight or hardness of the degree measure.
(3) Wrapped burned in the end: burn in the bottom of the wrapping cloth end PHYLON, but with a shoe designers in order to pursue the overall sense of design and technology, the best example is that the shoes in the end and the body of the shoe with the same kind of cloth, making the body of the shoe and the soles of the overall combination of, but also a bright spot in the shoe production process. This process is selecting the fabric wrap is formed of PHYLON in the end, high-temperature burning in the mold, it becomes in the end as we can see that the LB1 cloth texture shoes.
The end of 2.PU in: In addition to the end PHYLON and EVA midsole, PU midsole is also very common, PU end of the greatest advantage is the flexibility and toughness.
3 end of the package: a lot of shoes with built-in end of the structure, also known as the end of the package. Like the familiar T-MAC series, NIKE series of wind sent belong to the end of the package structure from the appearance of the end of the package consists of two parts of the outsole and upper, but the structure and outsole, midsole and shoes surface composed of three parts, but in the end package in the upper inside.
4.PU overall soles: ADI and NIKE when used in the soles are not a lot, PU soles belong to the low temperature molding soles. PU at the end there is a light, but not wet, a chemical reaction will encounter water layers eroded.
(5) taking into account the shoes wear better, try to use the PU of NR, BR, SBR, etc.
The decay is weather-resistant oxygen, resistance to UV. If the shoes you want to export, taking into account the high temperature resistant to 80 degrees. (The temperature of the container)
The soles are multi-color products, additives to select non-polluting. The fillers are mostly white carbon black.
