What is EVA Material?

EVA is a lightweight, flexible, and durable material made by copolymerizing ethylene and vinyl acetate. The ratio of vinyl acetate to ethylene in the polymer chain can be adjusted to achieve different levels of flexibility and durability.

Applications of EVA in Shoe Sole Industry

The shoe sole industry has been one of the major beneficiaries of EVA’s versatile properties. Here’s how EVA is used in this industry:

1. Sole Material: EVA is a common material for shoe soles due to its durability, flexibility, and shock-absorbing capabilities. It provides comfort to the wearer and can withstand the stress of daily wear and tear.

2. Midsoles: In athletic shoes, EVA is often used in the midsole for its cushioning effect. It helps to reduce the impact on the feet and legs during physical activities.

3. Outsoles: While outsoles typically require more abrasion resistance, EVA can be compounded with other materials to improve its wear resistance, making it suitable for certain types of footwear.

4. Insoles: EVA is also used in insoles for its comfort and moisture-wicking properties. It can help keep feet dry and comfortable throughout the day.

5. Custom Orthotics: For those requiring custom footwear support, EVA is an ideal material due to its moldability and durability.

The use of EVA in shoe soles offers several advantages:

1. Comfort: EVA’s cushioning properties provide a comfortable walking experience.

2. Lightweight: The lightweight nature of EVA reduces the overall weight of the shoe, which is particularly beneficial in athletic footwear.

3. Cost-Effective: EVA is relatively inexpensive compared to other materials with similar properties, making it a cost-effective choice for manufacturers.

4. Customizable: EVA can be easily molded into various shapes and densities, allowing for a wide range of design possibilities.

5. Environmentally Friendly: EVA is recyclable, and many manufacturers are now using recycled EVA in their products to reduce environmental impact.

Wear resistance is a critical factor in the durability of shoe soles, especially for athletic and outdoor footwear. It determines how long a shoe will maintain its structural integrity and performance under regular use. Traditional EVA materials, while offering excellent cushioning and flexibility, may not always provide the level of wear resistance required for high-stress applications. This is where silicone masterbatch wear resistant agents come into play, Significantly improves the abrasion resistance of EVA soles.

SILIKE Anti-abrasion masterbatch NM series especially focuses on enlarging its abrasion-resistance property except the general characteristics of silicone additives and greatly improves the abrasion-resisting ability of shoe sole compounds. Mainly applied to shoes such as TPR, EVA, TPU and rubber outsole, this series of additives  focuses on improving the abrasion resistance of shoes, prolonging the service life of shoes, and improving comfort and practicability.

Advantages of Silicone Masterbatch Wear Resistant Agents NM-2T

Anti-abrasion masterbatch ( Anti-wear agent ) NM-2T, particularly developed for EVA or EVA compatible resin system to improving the final items abrasion resistance and decrease the abrasion value in the thermoplastics. 

Compare to conventional lower molecular weight Silicone / Siloxane additives,like Silicone oil, silicone fluids or other type abrasion additives, SILIKE Anti-abrasion Masterbatch NM-2T is expected to give a much better abrasion resistance property without any influence on hardness and color.

Incorporating silicone masterbatch anti-wear agent NM-2T into EVA shoe soles offers a multitude of benefits:

1. Enhanced wear resistance: The addition of Anti-abrasion masterbatch ( Anti-wear agent ) NM-2T significantly improves the wear resistance of EVA materials, ensuring that the soles last longer under harsh conditions.

2.Improved machinability: Adding Anti-abrasion masterbatch NM-2T in the right amount can improve the processing lubrication performance of EVA materials, improve the flow of resin, and improve the surface quality of EVA shoe soles.

3.Meets abrasion tests: meets DIN, ASTM, NBS, AKRON, SATRA, GB abrasion tests and the addition of Anti-abrasion masterbatch NM-2T has no effect on the hardness and colour of the shoe material.

4. Eco-Friendly: Silicone masterbatch, making it a more environmentally friendly option compared to traditional additives.

Silicone masterbatch wear resistant agents, their ability to enhance the durability, comfort, and performance of shoe soles has made them an indispensable component in the production of modern footwear. As the technology continues to advance, we can expect to see even more innovative applications of silicone masterbatch wear resistant agents, further pushing the boundaries of what is possible in the world of footwear.
