How to identify the EVA soles among all kinds of soles

Written by

EVA as the commom material for the footbed of their shoes.

EVA is a dense foam which acts as an excellent and durable shock absorber in the sole of many shoes. Originally popularized in athletic shoe soles, EVA material is now being used industry wide and in a wide variety of shoe shapes and styles.

 EVA actually technically named Ethylene Vinyl Acetate and is a polymer widely used in a number of applications – from bio engineering to photovoltaic modules (such solar panels). In the shoes field, these companies are using the expanded rubber of foam version forms of the polymer.

Why EVA is considered more eco-friendly is that it doesn’t use chlorine in its production. That represents there is less toxicity released during degradation in a land fill somewhere if you discard your shoes by accident.

 Recycled EVA is considered more eco-friendly for not only is the material itself environmentally safer, but it is likewise not being simply discarded and is instead being re-used over and over again.

 EVA is also widely used in Vegan shoe goods because it is man made and friendly to animals.

 Moreover, shoes makers are also using EVA almost as a binding agent for other eco-friendly shoe materials. Jute, bamboo, cork and other materials are incorporated with the EVA to create better functions, and a great look, even an eco friendly shoe.

Rubber - whether natural or synthetic, has a long coiled polymer chain. For putting the material to best use-to get good strength, age, oil, oxidation resistance, we must mix the rubber with a vulcanising chemical, which will crosslink the polymeric chains

In TPE or TPR, these chains are already crossbound by physical aggregation or domains which prevent the chains from slipping past each other. On heating these hard domains yield allowing the polymer to flow like a plastic which can be made to fill a mold.

 On cooling, the TPE solidifies again into a hard mass. Like plastics, the material can be repeatedly heated to flow and cooled till they are thermally decomposed. TPEs are man made to have these "block" sections in the polymer.

 ThermoPlastic Rubber TPR is best described a material which has both the characteristics of rubber and plastic. Typical applications are the hard rubber/plastic soles on many shoes or the the rubber/plastic material used on hane tool grips.

 ThermoPlastic Elastomer (TPE) are a softer version of TPR. TPEs permit fabrication of "rubber-like" articles with the speed, efficiency, and economy of injection molding, extrusion, or blow molding. This material is typically used where flexibility and soft-touch is desired in the application.

 step 3: cutting the plate into strips;    

step 4: overlapping the strips into several groups and each group having a desired weight;    

step 5: heating the overlapped strips in step 4 in a mold to form an outsole, herein the mold has pattern defined in an inside thereof, and    

step 6: trimming the outsoles.    In the method, there is no peeling process so that the EVA material that can be saved is about 30% to 40% of the quantity of EVA material that is used in the conventional method. The mold has patterns defined in an inside thereof so that the outsoles made by the method of the present invention are final products. The size of the mold mentioned in step 5 is ? to ? of the full size of a conventional mold.      While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.     

 

What is claimed is:           

 1. A method of fabricating an EVA outer sole comprising the steps of:      

(a) mixing an EVA composition with a foaming agent to form a mixture;       

(b) pressing said mixture to form a mixture plate;      

 (c) cutting said mixture plate to form a plurality of mixture strips;       

(d) overlapping a plurality of said mixture strips one over the other to form an overlapped set of said mixture strips having a desired weight.    

   (e) heating said overlapped set in a single mold which has a pattern defined internally thereon so as to form a concurrently cured and shaped outer sole having said pattern; and,
