Black rubber sheet knowledge

A wide range of soles material




Sole material varied, with TPR soles, MD soles, MD rubber, EVA soles, rubber outsole, PVC soles, PU soles, RB soles, RS soles, TR soles, TPU soles, plastic soles.


Explain the concept of the next:


MD, EVA


First to say what is MD: MODEL or PHYLON dragon collectively


2. So what is PHYLON: (commonly known as the dragon) is a kind of material to do the soles of the shoes used in general, the use of heat compression EVA foam made of mixed material (EVA secondary pressure molded products) Light, elastic and seismic performance is good, the hardness is controlled by the foam temperature.


3. So what is EVA: Ethylene Vinyl Acetate - Vinyl acetate fiber. Light and flexible chemical synthesis of substances.


So: MD soles inside must contain EVA, MD end also called PHYLON end. Such as MD = EVA + RB or EVA + RB + TPR Some shoes are RB + PU and so on.


RB, PU, PVC, TPU, TPR, TR


1. What is RB: RB is an abbreviation for English rubber (rubber); rubber contains natural rubber, synthetic rubber (see Appendix I for details). Rubber: used in a variety of sports shoes outsole.


2. What is PU: Polyurethane High-molecular-weight polyurethane synthetic material, often used in high-density, durable foam-based materials in the midsole.


3. What is PVC: polyvinyl Chloride PVC, natural yellowish translucent, shiny. Whitening at the fold will appear.


4. What is TPU: full name of thermoplastic polyurethane elastomer (Thermoplastic Polyurethane), which is a diisocyanate and macromolecular polyols, chain extenders generated by the reaction of linear polymer materials.


5. What is TPR: Thermoplastic Rubber, a material that combines the properties of rubber and thermoplastics with the properties of rubber and can be processed and recycled as thermoplastics. It can be molded using conventional plastic forming machines, Extrusion molding, blow molding made of rubber products.


6. What is TR: TPE and rubber synthetic materials, with the appearance of more patterns, feel good, color Yan, smooth finish, high technical content, but also can be 100% recycled, are environmentally friendly shoe soles material.


Sole identification and characteristics of the materials:


About PU, PVC, TPR, RUBBER recognition!


PU is the lightest and most wear-resistant, of course, the price is the most expensive.


PU material soles are very good, very light in the hand, the holes on the back of the sole are round.


PVC material soles in the hands than the TPR to heavy.


TPR shoe soles elasticity is better than PVC, the soles of the firm hold, naturally fall, if it can bounce it is TPR


PVC material soles are cheaper than TPR, but the quality is not good, especially in winter, it is easy to break the end.


PVC shoe soles have a feature that there is no injection hole, as well as smell with the nose, there is taste. Put a long time, then the long white things.


The sole surface of the TR is very bright, harder than regular TPR soles, and TR has more injection holes than TPR.


Weight: RUBBER (rubber) the most important, PU, EVA the lightest,


Material: PU expensive, EVA, TPR moderate, PVC cheapest,


Process: TPR is a formed, and PVC to be processed, ABS is generally high-heeled shoes, expensive and hard,


Application: PVC is more used in the material or non-weight parts, or create children's shoes; PU leather can be applied to the fabric of footwear or bear the weight of the site. In the bag, the more applicable PVC leather. This is because the items in the bag are different from the ones worn in the shoes and do not radiate heat; do not have to take personal weight.


PU, PVC distinction is relatively easy, from the corner of PU's bottom cloth is much thicker than PVC, there are differences in feel, PU feel soft; PVC feel harder; can also be used to burn fire, PU's Taste is much lighter than the taste of PVC.


Appendix I:


    1, natural rubber


Natural rubber is mainly derived from the Clover rubber tree, when the rubber tree's skin is cut open, it will flow out milky juice, called latex, latex by condensation, washing, forming, drying that natural rubber.


    Synthetic rubber is made by synthetic methods, using different raw materials (monomers) can be synthesized different types of rubber.


    2, Universal rubber


    Refers to some or all of the rubber used instead of natural rubber, such as styrene butadiene rubber, butadiene rubber, isoprene rubber, etc., mainly for the manufacture of tires and general industrial rubber products. General demand for rubber is large, is the main varieties of synthetic rubber.


    Styrene-butadiene rubber:


    Styrene-butadiene rubber (SBR) is a copolymer of butadiene and styrene. It is the most widely used general-purpose synthetic rubber with SBR, SEB and thermoplastic elastomer (SBS).


    Butadiene rubber :


    Butadiene is prepared by solution polymerization, butadiene rubber has particularly excellent cold resistance, abrasion resistance and flexibility, but also has good anti-aging properties. The vast majority of butadiene rubber for the production of tires, a small part for the manufacture of cold products, cushioning materials and tape, rubber shoes and so on. The disadvantage of butadiene rubber is that the tear resistance is poor and the wet skid resistance is not good.


    Isoprene rubber:


    Isoprene rubber is a short name for polyisoprene rubber, produced by solution polymerization. Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability. Isoprene rubber raw (raw) strength was significantly lower than natural rubber, but the quality of uniformity, processing performance superior to natural rubber. Isoprene rubber can be used in place of natural rubber to make truck tires and off-road tires. It can also be used to produce various kinds of rubber products.


    Isoprene rubber:


    Ethylene Propylene rubber and ethylene as the main raw material synthesis, anti-aging, electrical insulation and ozone resistance outstanding. Ethylene-propylene rubber can be a large number of oil-filled and filled with carbon black, lower product prices, ethylene propylene rubber chemical stability, abrasion resistance, elasticity, oil resistance and styrene butadiene rubber close. Ethylene Propylene rubber is used for a wide range of purposes, can be used as tire sidewalls, tape and tube and automotive components, but also for wire, cable sheath and high pressure, high pressure insulation materials. Can also create plastic shoes, sanitary products and other light-colored products.


    Neoprene:


    It is chloroprene as the main raw material, by homopolymerization or a small amount of other monomers copolymerization. Such as high tensile strength, heat resistance, light resistance, excellent aging resistance, oil resistance are better than natural rubber, styrene butadiene rubber, butadiene rubber. Has a strong flame resistance and excellent anti-flammability, high chemical stability, good water resistance. The disadvantage of neoprene is the electrical insulation properties, poor cold resistance, raw rubber instability in storage. Neoprene is used for a wide variety of purposes, such as foreskin and belt wrapping, wires and cables, as well as oil-resistant hoses, gaskets, and chemical-resistant equipment linings.
