How are ethylene vinyl acetate (EVA) granules made?

Everyone knows that Lego bricks are one of the most popular toys in the world, but do you know what they are made of? Ethylene vinyl acetate (EVA) granules are one of the main materials of Lego bricks. How are they made?

Ethylene vinyl acetate (EVA) granules is a polymer material that has excellent softness and impact resistance and can maintain stable physical properties at different temperatures. This material is widely used in toys, footwear, packaging materials and other fields. The preparation process of ethylene vinyl acetate (EVA) granules includes multiple steps such as polymerization, extrusion and granulation, and each step requires precise control to ensure the quality and stability of the particles.

In addition to its application in Lego bricks, ethylene vinyl acetate (EVA) granules are also widely used in the midsole material of sports shoes. Due to its excellent shock absorption and comfort, EVA midsoles have become the preferred material for many sports shoe brands. In addition, ethylene vinyl acetate (EVA) granules can also be made into products of various shapes and densities through injection molding, such as floor mats, playground facilities, etc., meeting people's needs for comfort and safety.

With the improvement of environmental awareness, the sustainability of ethylene vinyl acetate (EVA) granules has also attracted much attention. Compared with traditional plastic materials, ethylene vinyl acetate (EVA) granules can reduce the impact on the environment during production and recycling, so it is considered to be an environmentally friendly material. In the future, with the continuous advancement of science and technology, the application field of ethylene vinyl acetate (EVA) granules will continue to expand, bringing more convenience and comfort to people's lives.

As a multifunctional material, ethylene vinyl acetate (EVA) granules is not only widely used in Lego blocks, sports shoes and other fields, but also has attracted much attention for its environmental protection characteristics. By deeply understanding the preparation and application of ethylene vinyl acetate (EVA) granules, we can better appreciate and understand the science and technology behind products such as Lego blocks. Looking forward to the future, ethylene vinyl acetate (EVA) granules will continue to bring more surprises and convenience to our lives.
