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

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.

  • Safety shoes outsoles

    1, outsole material, it is the use of natural rubber or synthetic rubber.
           (1) Natural rubber: natural rubber advantage is that it is very soft, flexible and good, and can adapt to a variety of sports, but the disadvantage is obvious that very wearable. Multi-purpose indoor sports shoes, natural rubber.
  • 2, divided into synthetic rubber in the wear-resistant rubber, green rubber, air rubber, sticky rubber, hard rubber, with carbon rubber.
  •        (1) Wear rubber: wear rubber wear resistance and toughness are very good, so very durable, this rubber material is generally in tennis shoes outsole use.
           (2) green rubber: also known as recycled materials rubber, the rubber outsole contains up to 10% recycled rubber, the main purpose is to protect the environment.
           (3) Air Rubber: Rubber contains air, there is some cushioning, but not very wearable, use is not very extensive.
           (4) sticky rubber: sticky rubber is characterized by flexibility, better, and very slippery, generally used in indoor sports shoes.
           (5) hard rubber: hard rubber outsole rubber material is the most comprehensive of the rubber, tough and very slip resistant, uses naturally very wide. Multifunctional shoes and basketball shoes are mostly to do with such a rubber outsole.
           (6) with carbon rubber: rubber material in general have added a carbon element, making more tough wear-resistant rubber, running most of the use of such rubber, shoe soles and in part will be left hind paw BRS letters marked to indicates outsole with carbon rubber used.
  • 3, rubber outsole play: This outsole is not common, this is the end of the raw industrial glue, stir through the mixer, and then into the mold thermoforming tank, which is characterized by soft and very non-slip.

  • Different types of boot outsoles?
  •           The outsole is that part of the boot that comes in direct contact with the ground.  Depending upon the activity the boot is designed for, the tread pattern can range from very aggressive (with hard and sharp-edged cleats) to somewhat smooth (with shallow and wavy ridges), with just about everything in between.  Most outsoles, however, can be classified in one of four categories: Vibram lugs, air bobs, shallow tread and hiking/athletic.

Advantages of TPR TPE soles

Written by
  • TPR and TPE soles advantages
  •      generally available thermoplastic molding machine, does not require special processing equipment.
  •      a substantial increase in production efficiency. Can be directly vulcanized rubber injection molding machine, the time from about 20min, shortened to less than 1min; need curing time is very short, it is already available direct vulcanization extruder production efficiency greatly improved.
  •      3 easy to recycle and reduce costs. Waste generated in the production process (escape flash, out of waste plastic) and the final waste can be returned directly reused; used TPE old products can be simple regeneration recycling, reduce environmental pollution, expanding sources of renewable resources.
  •      4 Conservation. Most thermoplastic elastomers do not require curing or curing time is very short, can effectively save energy. Energy consumption in high-pressure hose example: rubber 188MJ/kg, TPE is 144MJ/kg, can save energy up to 25% or more.
  •      5 wider field of applications. TPE combines the advantages of rubber and plastic, rubber industry has opened up new fields of application.
  •      can be used for plastic reinforced, toughened. Since the reinforcement, the formula simplifies, with the impact of constraints on the polymer dose is small, the quality of performance easier to grasp.
              TPE heat resistance than rubber, as the temperature rises and properties decreased greatly, and thus the scope is limited. Meanwhile, deformation and elastic recovery and durability equivalent to less than rubber, the price is often higher than the same rubber. Nevertheless, TPE advantage is still very prominent, a variety of new TPE products are constantly developed. 
               As an energy saving rubber new materials, the development is very promising.
