EVA material, known as Ethylene Vinyl Acetate (EVA) copolymer, is a non-toxic, odorless, transparent thermoplastic. During the manufacturing process, by adjusting the content of vinyl acetate (VA) (generally 5%-40%), EVA materials introduce vinyl acetate monomer into the molecular chain, thus reducing its high crystallinity and improving toughness, impact resistance, filler compatibility and heat sealing properties.
The advantages of EVA material in shoe materials are mainly reflected in the following aspects:
Lightweight: EVA material is lighter than other traditional shoe materials such as rubber or leather, which helps to reduce the overall weight of shoes and improve wearing comfort, especially for people who stand or walk for a long time, which can significantly reduce the burden on the feet.
Flexibility and elasticity: EVA material exhibits excellent flexibility and rubber-like elasticity, and maintains good flexibility and transparency even at low temperatures. This allows the EVA sole to conform to the shape of the foot, providing a comfortable wearing experience and reducing foot fatigue.
Abrasion resistance: EVA material has excellent abrasion resistance and can withstand the friction and wear and tear of daily use, thus extending the life of the shoe. For people who frequently engage in outdoor activities or sports, the abrasion resistance of EVA soles can provide long-lasting protection.
Improving the abrasion resistance of EVA footwear materials can be approached from a number of aspects, and the following are specific recommendations:
Optimize the formulation:
Addition of abrasion-resistant agents: The abrasion resistance of EVA shoe materials can be significantly improved by adding silicone masterbatch abrasion-resistant agents or other effective abrasion-resistant additives. Abrasion-resistant agents can improve the surface smoothness of shoe materials and reduce friction and wear.
Adjusting the ratio of stearic acid, calcium carbonate, EVA granules, talc, foaming agent, methyl silicone oil and other components ensures that the soles exhibit excellent abrasion resistance while maintaining lightness, flexibility and durability.
Selection of suitable fillers and additives:
Add fillers such as carbon black and glass beads to enhance the anti-wear performance of EVA materials.
Select some special additives to improve the anti-slip and anti-impact properties of EVA materials to further enhance their abrasion resistance.
Improve the manufacturing process:
Adopt advanced foaming technology and good mold design to manufacture denser and more uniform EVA soles, so as to improve its abrasion resistance.
Quality control of the manufacturing process is also very critical to ensure the consistency of the performance of each batch of EVA material.
As one of Enhance the abrasion resistance of EVA soles and increase the service life of the products, Xianmen Xiangxi New Material introduces our silicone wear-resistant agent series.
Our product is a polymer silicone launched by our company with vinyl soft rubber composite carrier, the material is mainly used in shoe materials, soft rubber system. We have 5 grades DX051,DX052P,DX067T,DX053 and DX5015. It has better compatibility and fast mixing effect in the process of using, meanwhile, it has better coating effect for filling.It makes the material have better release performance and smooth performance, meanwhile, it can also improve the shoe material’s splash, black line, reduce DIN abrasion, abrasion marks and other functions.
