What's the difference between sole material MD and TPR?
The mixed material made of EVA foam MD by heating the compressed (two high pressure molding of EVA) lightweight, flexibility and good anti-seismic performance, hardness by foaming temperature control; TPR thermoplastic rubber (Thermoplastic Rubber), is a kind of rubber and thermoplastic properties of materials, rubber the performance and processing and recycling by thermoplastic plastics, can use ordinary plastic forming machine with injection molding, extrusion molding, blow molding is made of rubber products.
TR:TPE and rubber synthetic material, with the appearance of many patterns, feel good, bright color, high smoothness, high technical content, and can be recycled 100%, belongs to environmental protection type sole material.
TPR: thermoplastic rubber (Thermoplastic Rubber), is a kind of rubber and thermoplastic properties of materials, rubber performance and processing and recycling by thermoplastic plastics, can use ordinary plastic forming machine with injection molding, extrusion molding, blow molding type made of rubber products.
A general term for 1.MD:MODEL or PHYLON Dragons2.PHYLON: (commonly known as the Dragon) is a shoe sole material used in bottom, mixed material made of EVA foam compression heating. (two high pressure molding of EVA) lightweight, flexibility and good anti-seismic performance, hardness by foaming temperature control.3.EVA:Ethylene, Vinyl, Acetate-, vinyl resin, acetate fiber, light, resilient chemical compound. So: MD soles must contain EVA, and the bottom of the MD is also called PHYLON. Such as MD=EVA+RB or EVA+RB+TPR, and some shoes are RB+PU and so on. RB, PU, PVC, TPU, TPR, TR4.TPU: full name thermoplastic polyurethane elastomer (Thermoplastic, Polyurethane), it is a linear polymer material produced by diisocyanate and macromolecule polyol and chain extender.
