Is EVA material good for sole or good for rubber?Which is more wearable?
Rubber: for all kinds of sports shoes outsole; advantages: good abrasion resistance, anti slip, flexible, easy to break, good softness, good stability, extended shrinkage, good hardness and good bendability. Disadvantages: heavy weight, easy frosting (which is the quality problem, not easy to corrosion (environmental) problem)
TPR: to TPR after injection molding hot pellets, used to jog, walk, casual shoes insole, outsole. Advantages: easy molding and cheap. Disadvantages: heavy material, poor abrasion (no wear), flexibility is poor, poor bending (without folding), shock absorption ability
PHYLON (MD): two high pressure molding product is EVA, the main ingredient in running shoes, tennis shoes, basketball shoes at the end of the world, but also can be used for casual shoes outsole. Advantages: lightweight, flexible, fine appearance, good softness. Easy cleaning, hardness, density, tensile strength, elongation, tear. Disadvantages: easy to corrosion. The adverse environmental protection, high temperature easy to wrinkle, easy to shrink.
EVA: ethylene vinyl acetate copolymer, polymer materials. Commonly used in jogging, walk, leisure shoes, foot training shoes. Advantages: lightweight, good elasticity, flexibility is good, not easy to wrinkle, with excellent color, suitable for all kinds of weather. Disadvantages: easy water, not easy to corrosion, easy dirty adverse environmental protection.
PU: polymer polyurethane synthetic material, often used for basketball and tennis shoes in the bottom, also can be directly used in casual shoes outsole. Advantages: density, high hardness, wear resistance, good flexibility, good oxidation resistance, corrosion is not conducive to environmental protection, easy to fold. Disadvantages: strong water absorption, easy, easy to turn yellow the fracture elongation rate, poor water resistance, bottom perishable.
