Varied rubber out soles

Written by

In order to better understand what everyone silicone rubber, rubber sole we have classified for

1, natural rubber or synthetic rubber adhesives.
(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. The following is a detailed description;

(1) Wear rubber adhesive: 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.

A light material for shoes outsoles-TPR

Written by
  • Sole as an important part of the shoes, how can the outsole reduce the cost of the premise while maintaining the testing requirements of the international market and consumer demand is one of the important competitive. At present, the sole type of material that can be purchased in the market range of different pattern, rubber, thermoplastic rubber, polyurethane or thermoplastic polyurethane, and the traditional thermoplastic rubber TPR typical formula of thermoplastic elastomer TPE58-65% poly-alpha methyl styrene resin ATL3-5% nano-calcium CCR20-25% polystyrene PS12-16%, thermoplastic styrene-butadiene rubber SBS2-5%, 5-10% of a softening oil, anti-violet agent UV (Model 301 ) 1-3% anti-oxidant ANTIOXIDANTS (Model TM-3) 1-3% titanium dioxide TITANIUMDIOXIDE (Model K930) 1-5% the ultralight foam powder (Model A-9) 3-5 ‰ , low temperature expansion agent 3-5 ‰, the white foaming 3-5 ‰, which the thermoplastic elastomer TPE, their production processes to the corresponding formula of raw materials into the mixer mixing TPR particles, and then pour the TPR particles into the barrel of raw materials, according to the requirements of the color graded pellets of different colors after heating, graded injection installed mold machine table out of the last cooling finished, this traditional recipes TPR outsole due mainly formula is chemical raw materials TPE proportion of weight, twists and turns and poor resilience, the the traditional TPR proportion of approximately 0.8-1.1 twists and turns of about 50 000 times without damage, resilience is about 50-70 degrees does not collapse, NBS resistance grinding of approximately 20-42%.
  •              While traditional EVA typical recipe of ethylene (E) and vinyl acetate (VA) EVA70 80% of nano-calcium CCR10-15%, 5-8% filler, ZnO1-zinc oxide 5%, and so on, the main ingredients EVA, the quantity used in their production processes to try out the mold tryout recorded data recorded in accordance with the tryout, EVA raw material particles pounds weight placed fixed dissolved, a fixed weight of pellets poured into the mold off after heating 6-7 minutes (temperature of 180-185 degrees), and then remove mold the bottom of the finished product, due to the early-shaped outsole surrounding smooth on the corresponding number, so the early-shaped outsole surrounding Roughing mold, smooth pressed into the mold and cover push the heating station about 10 minutes of heating temperature of 170-180 degrees, mold into a cooling station mold cooling after about 5 minutes pull out the finished bottom and flash trimming . On traditional recipes EVA outsole is characterized by light weight, but its main ingredients for the EVA so poor wear resistance of about 15-20%, and the production process is more complex capacity is not high, the cost is correspondingly high.

TPR sole invention

Written by
  • An outsole (1) for a shoe has a backing member (4) of thermoplastic rubber and on an area of the exterior surface of that backing member an intermediate layer (12) of thermoplastic polyurethane and an outermost layer of fabric (10), the area comprising at least 51 percent of the contact surface of the outsole. In producing the outsole, a sheet of fabric is overlain with a sheet of thermoplastic urethane, the sheet is heated to about the melting point of the TPU to permit the TPU to adhere to the fabric, and the fabric is cooled. The TPU-covered fabric is cut to the size and shape required to fit a backing member, and position in a mold on a bottom surface of a mold, and a quantity of TPR is injected at a temperature lower than the melting point of the TPU but high enough to render the TPU tacky, to insure the inherence of the TPU-covered fabric to the backing, including the resultant outsole.

Outsole invention background

Written by
  • OUTSOLE Background of the Invention
  • This invention relates to inserts in the tread surfaces of outsoles.
  • It is well known in the art to provide inserts
  • 5 in the wear surfaces of outsoles to thereby impart to the outsole various desirable characteristics, e.g., water proofing, cushioning, flexibility, increased friction, etc. It is desirable to enhance the adherence of such inserts to the remainder of the outsole and to
  • 10 reduce the steps necessary in the manufacturing of such outsoles.
  • Summary of the Invention In general, the invention features an outsole comprising a first sole component of oldable material, 15 and at least one other sole component around which is molded the first sole component, the other sole component forming at least a portion of the wear surface of the outsole.
  • In its method aspect, the invention features . 20 cutting an insert component, applying an adhesive to the one surface of the insert component, rigidly securing the insert component within a mold with the one surface facing upward, closing the mold, and injecting moldable material, at elevated temperature into the mold, thereby ■• 25 allowing the moldable material to flow around and, in cooling, adhere to, the insert component.
  • In preferred embodiments the moldable material is thermoplastic rubber; the insert component is open cell crepe rubber; the surface of the insert component 30 opposite the one surface is deskidded prior to insertion of the insert component in the mold; the insert component is uniformly approximately between 1/4 and 3/16 of an inch thick; and the durometer value of the insert component is greater than that of the moldable 35material.

The way of manufacturering EVA outsole

Written by

The way of manufacturering EVA outsole

  •        A process for manufacturing an ethylene vinyl acetate (EVA) sole that involves weighing molding compounds for manufacturing the sole. The molding compounds include, by weight, 65-75% of ethylene vinyl acetate pellets, 3-5% of blowing agents, 20-30% of fillers, and 1-2% of crosslinking agents. The molded compounds are mixed, and extruded by means of a twin screw extruder so as to form a web of unfoamed extruded output. The web is cut into sheets.
  •         At least one of the sheets is placed into a first mold unit, which is heated and pressurized so as to form a rough foamed sole.

  •         The rough foamed sole is placed into a second mold unit, which is heated, pressurized, and cooled so as to form an embossed sole with a predetermined pattern. The embossed sole is trimmed so as to form a finished ethylene vinyl acetate sole.
