Main advantages of secondary foaming EVA material:
eva foam soleIt has good softness and rubber-like rebound. It has good shockproof\/cushioning performance, cold resistance, aging resistance and ozone resistance. At the same time2 times foaming EVAThe material is also non-toxic, with a density of about 0.25. The hardness can be adjusted in a wide range, which can be around 25C-75C. The lower the hardness, the lower the density, and the better the softness. But the physical properties such as tearing and tensile strength will be poor, and the higher the hardness High, the higher the density, the better the physical properties such as tearing and tensile strength, but it will lose softness and resilience. Generally, 50C-60C is recommended.
The material is firstly foamed into an embryo, and then placed in the mold twice to be heated and formed, and it must be fully cooled to shape, so the shrinkage deformation is small, and the shape and size are well controlled.
Our company uses the characteristics of the secondary foamed EVA material to develop a lightweight, high-quality EVA midsole with good rebound cushioning performance, making walking or running more comfortable and comfortable. We have developed camouflage, multi-hardness, wear-resistant outsoles, etc. Rich product categories, also developed the integrated molding of rubber and EVA in the mold, reducing the post-manual lamination process.
