Shoes in the bottom of the puncture in the PHYLON prevention is the difference between bottom and EVA?
Now shoe bottom of anti puncture is the PHYLON bottom and bottom both in EVA is more 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, the earliest shoes 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, have we now call EVA in the bottom.
EVA in the different between bottom and bottom in the PHYLON: now in the shoe bottom use most is bottom of PHYLON, PHYLON biggest characteristic is light, good elasticity, has the very good cushioning performance, PHYLON 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.
A foam: the material injection mold by high temperature after heating time after molding shoes in the bottom, is called a foam in the bottom, bottom of the EVA shoes.
Secondary foam: 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.
