Raw rubber soled is what

Written by

Raw rubber sole


  •        Raw rubber is without plastic, rubber mixing collectively, is to create the most fundamental rubber raw materials, including natural rubber and synthetic rubber. Our daily said students wear rubber-soles, where the raw rubber-soles rubber sole is actually cooked, raw rubber is processed, except that it looks like raw rubber is our convention a mistake Bale.
            
          Plastic raw rubber floor less effective, hardness, low density, easy to wear and breakage; cooked just the opposite characteristics of rubber, wear resistance and toughness. Cooked glue widely used, such as automobile tires; raw rubber used only for production of low-end household items, such as slippers.

 ¿Qué es la suela de goma

  •       Suela de goma está hecho de caucho natural o caucho sintético producido y realizado. Debido a que es un compuesto de caucho de polímero. Por lo tanto, la suela de goma de alta elasticidad, una alta resistencia a la abrasión, y se sometió a repetidos de flexión, de estiramiento, compresión y no destruidos. También cuenta con el ácido y del álcali, tan lluvioso adecuado para usar. Ahora en el mercado una gran cantidad de calzado deportivo son casi siempre con una suela de goma hecha de. Como baloncesto, fútbol, ​​zapatillas de  tenis. Debido a que ambos pertenecen al deporte más violento, por lo que están obligados a tener una alta resistencia a la abrasión suela. De hecho, el uso de caucho es todo movimiento suelas de caucho colectivamente, de acuerdo con los materiales específicos y los ingredientes de división, suela de caucho también se puede dividir en un caucho natural delicado, de caucho resistente al desgaste, de caucho verde, caucho de aire, y la suela de goma con el carbono y así sucesivamente.
                El caucho es suave, elástico muy fuerte, muy fácil de distinguir, mano elasticidad squeeze es, con el olor tiene un borrador de sabor similar que sea; Shuaixiang suelo duro, hay indicios de que van a jugar.
           Suela de goma de los zapatos deportivos más ver como material, desgaste diario y el mantenimiento también deben prestar atención a los siguientes atletas o deportes que aman la gente debe comprar a desgaste de suela de goma calzado deportivo, que es extender la vida de sus zapatos, y más o menos probable que trata de recordar a lavar, se ve obligado a limpiar después del uso hormas ayudará a restaurar los zapatos del prototipo. ¿O será el relleno de cartón en sus zapatos, informó de que el efecto de doble beneficio, no sólo puede ayudar a restaurar la forma de los zapatos, pero los zapatos se pueden absorber rápidamente el exceso de humedad.

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.
