6-steps make outsole less slippery

Written by
  • New shoes, especially those with plastic or leather soles, are often slippery on wet or smooth surfaces. Sometimes when the tread on the soles or the soles themselves start to wear out, your favorite shoes can become slippery again. Before deciding you can't wear the shoes, try some quick fixes to make them less slippery.

6-steps make outsole less slippery

What is Rubber outsoles

Written by

   Rubber outsole is made from natural rubber or synthetic rubber produced and made. Because rubber is a polymer compound. Therefore, the rubber soled high elasticity, a high abrasion resistance, and subjected to repeated bending, stretching, compression and not destroyed. Also has the acid and alkali resistance, so rainy suitable to wear. Now on the market a lot of sports shoes are almost always with a rubber outsole made ​​of. Like basketball, soccer, tennis shoes. Because both belong to the more violent sport, so are required to have a high resistance to abrasion outsole. In fact, the use of rubber is all rubber soles movement collectively, in accordance with the specific materials and ingredients division, rubber outsole can also be divided into a delicate natural rubber, wear-resistant rubber, green rubber, air rubber, and rubber outsole with carbon and so on.
         Rubber is soft, elastic very strong, very easy to distinguish, hand squeeze elasticity is; with the smell has a similar taste eraser that is; hard Shuaixiang ground, there are signs that will play.
         Rubber outsole sports shoes most see as material, everyday wear and maintenance also need to pay attention to the following athletes or sports loving people should purchase to wearing rubber outsole sports shoes, which is to extend the life of your shoes, and more less likely to try to remember to wash, it is forced to clean after use shoe trees will help restore the prototype shoes. Or will cardboard padding in his shoes, reported to have the double benefit effect, not only can help to restore the shape of shoes, but shoes can rapidly absorb excess moisture.

Rasgos de TPR suela

Written by

Único material TPU no como de un solo uso
Pero como el único material auxiliar, es por lo general los zapatos juegan un papel en el apoyo armado
El TPR es el único material, similar a la suela de goma, ya que normalmente solemos usar pantuflas, sandalias son inferior TPR
Pero la desventaja no es usable TPR
Superficie del material de TPU es suave, duro, después de todo,
El TPR es un tipo de caucho-como la textura es muy suave y se puede plegar

Cómo identificar soles EVA

Written by
  • ¿Qué es EVA?

          Único material EVA utilizado es copolímero de etileno / acetato de vinilo (también conocido como copolímero de etileno - acetato de vinilo), es etileno (E) y acetato de vinilo (VA) copolímero en el sistema, la llamada Inglés: etilenevinilacetato. 
           Referido a EVA, el contenido de 5% a 40%. En comparación con polietileno, EVA, introducido en la cadena molecular del monómero de acetato de vinilo, lo que reduce la alta cristalinidad, una flexibilidad mejorada, resistencia al impacto, resistencia al calor y la compatibilidad de embalaje rendimiento de sellado, son ampliamente utilizados en los materiales de los zapatos de espuma, películas funcionales, las películas de embalaje, adhesivos, alambre y cable, juguetes y otros campos.
  • Únicas identificaciones EVA
  •        ① suave, flexible, y tiene un cierto grado de elasticidad de la goma: baja temperatura, las temperaturas tan bajas como-58С sigue siendo flexible.
           ② fuerza moderada mecánica, resistencia al desgarro, resistencia a la perforación, resistencia, resistencia al estrés resistencia a la fisuración.
           ③ debido polaridad de etilo del EVA aumenta la propiedades eléctricas elasticidad y viscosidad, cristalinidad y, y puede disolverse en disolventes de hidrocarburos y aceites, resistentes al envejecimiento y al ozono. EVA única clase de los casos sólo después de unos años en el uso de un grupo de la suela a menudo aparecen amarillo y así sucesivamente.
           ④ suelas EVA sin puerto de inyección, cortar un pequeño trozo de encendido una vela quemada y derretida goteaba.

Chemical property of TPR sole      

       TPR thermoplastic elastomer as plastic, the substration of SBS. A functional composite modified elastomers made ​​of plastic. TPR material density 0.85 to 1.2 g / cc Hardness Shore 0-100A, the appearance of a transparent, translucent or color of the pellets or pelletized. TPR material having rubber elasticity because of transitivity, also known as thermoplastic rubber. Thermoplastic rubber, which when heated melt plastics, hot molding, the finished product is obtained after cooling, and need not, as natural rubber, synthetic rubbers, vulcanized to side with the use of the crosslinking properties. 
      
Differences between TPR and TPE
 
        Industry was also called the TPR TPE, is actually called habit issue. Elastomer TPE industry is often referred to as base composite modified SEBS made ​​of elastomeric material, the TPE TPR and the microstructure of the material is slightly different, reflecting the physical properties of the material still has some differences. TPR is an unsaturated bond because the SBS material modification is made, materials, chemical resistance, temperature resistance, hydrolysis resistance are not as good TPE.TPR bright surface material, dubbed a variety of bright colors and easy products, TPR easy to glue water , easy injection silk screen, can be used as beauty salon equipment, colored toys, injection silk screen toys, shoes raw materials.

How to identify EVA out soles

Written by
  • What is EVA ?
    EVA sole material used is ethylene / vinyl acetate copolymer (also known as ethylene - vinyl acetate copolymer), is ethylene (E) and vinyl acetate (VA) copolymer in the system, the English called: EthyleneVinylAcetate. Referred to EVA, the content of 5% to 40%. Compared with polyethylene, EVA as introduced in the molecular chain of vinyl acetate monomer, which reduces the high crystallinity, improved flexibility, impact resistance, heat resistance and compatibility packing sealing performance, are widely used in foam shoes materials, functional films, packaging films, adhesives, wire and cable and toys and other fields.
  • EVA sole identifications
  • ① soft, flexible, and has a certain degree of rubber elasticity: low temperature, temperatures as low as-58С is still flexible. 
    ② moderate mechanical strength, tear strength, puncture resistance, resilience, resistance to stress cracking resistance. 
    ③ due acetate polarity of the EVA increases the elasticity and viscosity, crystallinity and electrical properties, and can dissolve in hydrocarbon solvents and oils, resistant to aging and ozone. EVA sole class of cases only after a few years in the use of a group of sole often appear yellow and so on.
    ④ EVA soles without injection port, cut a small piece of lit a candle burnt and melted dripping.

Traits of TPR & TPU sole

Written by

TPU sole material not as single use
But as the sole auxiliary material, is generally the shoes plays a role in supporting reinforced
The TPR is the sole material, similar to rubber soles, as we usually wear house slippers, sandals are TPR bottom
But the disadvantage is not wearable TPR
TPU material surface is smooth, hard, after all,
The TPR is a kind of rubber-like texture is quite soft and can be folded

Outsole abrasion test

Written by
  • Outsole abrasion test
  • Abrasion means the process of wearing down, loss of material from surface or rubbing away by means of friction. Footwear sole wear by natural use or artificial abrasion either increases or decreases slip resistance on floors with and without lubricant. The objectives of this test are to study the effect of footwear sole abrasive wear on slip resistance. In terms of safety footwear, it is required to justify the abrasion of outsole. The outer sole is tested with an abrasion testing machine. The result of these test are the basis for the calculation of sole wear resistance. The soling materials abrasion machine gives a straight forward and realistic abrasion test for shoe soling and heel materials. The test pieces are drawn from side to side in straight line under load over an abrasive coated cloth supported on the machine. The cloth is moved at a specific speed, generates rolling inversion friction on the roller and the size loss of the test piece will be used to measure the wear resistance degree of the sample. In applications where an elastomer is subjected to frequent rubbing or abrasive actions as part of its use, it is of prime importance to ensure that the formulation used has a fair degree of resistance to abrasion.
  • One of the methods for determining the abrasion resistance of elastomer is by a Rotating Drum Abrasion Tester. In this test the elastomer under test is abraded against an abrading surface mounted over a rotating drum. The abrading surface has a specified abrading power. The test specimen, which is in form of a button, is held against it under a fixed load. The abrading surface is made to rub against the test specimen by rotating the drum at a fixed speed, the test specimen being meanwhile made to move along the axis of the drum. The ratio of the volume loss of a standard elastomer to the volume loss of the rubber under test, determined under the same conditions and expressed as a percentage, gives the abrasion resistance index of the rubber under test. The determination of volume loss by this method is suitable for comparative testing and for checking the uniformity of specified products. However, the results of this test give only limited information on the wearing behavior of elastomer in practice. When non-leather outsoles other than those from all rubber or all polymeric footwear are tested in accordance with EN ISO 20345. The relative volume loss shall be not great than 250 mm³ for materials with a density of 0.9 m/cm³ or less and not great than 150 mm³ for materials with a density greater than 0.9 cm³.
  • The machine gives an average of abrasion through the entire thickness of samples such as leather, rubber, tyre, elastic material, sole, polyester, polyurethane. The features of this machine high efficiency, good emersion of test result and easy operation.
