About the sole material

TPR sole, MD sole, MD rubber, EVA sole, rubber outsole, PVC sole, PU sole, RB sole, RS sole, TR sole, TPU sole

MD, EVA

1. What is MD first: the collective name of MODEL or PHYLON dragon

2. So what is PHYLON: (commonly known as Feilong) is a kind of material for soles. The midsole used in general shoemaking is a mixed substance made of heated and compressed EVA foam. (Belongs to EVA secondary high-pressure molding products) Features Lightweight, good elasticity and shock resistance, the hardness is controlled by the foaming temperature.

3. So what is EVA: Ethylene Vinyl Acetate-vinyl acetate fiber. Lightweight and elastic chemical synthetic material

So: MD soles must contain EVA, and MD soles are also called PHYLON soles.

For example, MD=EVA+RB or EVA+RB+TPR and some shoes are RB+PU, etc.

RB, PU, PVC, TPU, TPR, TR

1. What is RB: RB is the abbreviation of English rubber (rubber); rubber includes natural rubber and synthetic rubber (see Appendix 1 for details). Rubber: used for outsoles of various sports shoes.

2. What is PU: Polyurethane polymer polyurethane synthetic material, which is often used in the midsole of the back palm as a high-density and durable material based on foam rubber.

3. What is PVC: polyvinyl Chloride polyvinyl chloride, the natural color is light yellow translucent, shiny. Whitening occurs at the inflection.

4. What is TPU: The full name is thermoplastic polyurethane elastomer (Thermoplastic Polyurethane), which is a linear polymer material produced by the joint reaction of diisocyanate, macromolecular polyol and chain extender.

5. What is TPR: Thermoplastic Rubber (Thermoplastic Rubber) is a material that has both rubber and thermoplastic properties. It has the properties of rubber and can be processed and recycled as thermoplastics. It can be injection molded by ordinary plastic molding machines Rubber products are made by extrusion molding and blow molding.

6. What is TR: The synthetic material of TPE and rubber has the characteristics of various appearances, good hand feeling, bright color, high smoothness, high technical content, etc., and can be 100% recycled, which is an environmentally friendly sole material.
