Product Introduction of EVA Shoe Sole Granules
EVA Shoe Sole Granules are recycled EVA-based material granules developed for footwear manufacturers producing slippers, sandals, flip-flops, and molded shoe sole components. The material is based on Ethylene Vinyl Acetate (EVA) copolymer, with a typical vinyl acetate (VA) content range of 5%–40%. The incorporation of vinyl acetate reduces the high crystallinity of polyethylene and improves flexibility, toughness, impact resistance, and processing performance.
The current footwear grade is 45 Shore A, making it suitable for applications requiring a balance between softness, resilience, and structural support. The closed-cell structure provides low water absorption, moisture resistance, cushioning, and thermal insulation. Yleva supplies recycled EVA material from its China manufacturing base and supports customized requirements for hardness, color, foaming ratio, and packaging.

Production Process of EVA Shoe Sole Granules
We controls the production of recycled EVA granules from material preparation through final packaging. Recycled EVA feedstock is first selected and inspected according to the required product formulation. Suitable materials are then processed through cleaning, sorting, and preparation procedures before entering the compounding stage.
During compounding, the EVA material is mixed with the required additives and processing components. The formulation is controlled according to the target hardness, color, processing behavior, and footwear application. After homogenization, the material is processed through extrusion equipment and cut into granules.
The finished material undergoes quality inspection before packaging. Key checks can include appearance, hardness, batch consistency, and processing characteristics. This production structure allows Yleva to maintain traceability and consistent manufacturing conditions for bulk footwear orders.
