The hardness of EVA can be adjusted according to different application requirements, and its hardness classification mainly includes the following types:
The hardness of high foaming EVA material is 5%~40%, which has good softness and elasticity. It is commonly used in the production of packaging materials, shoe materials, toys, etc.
The secondary foaming hardness of EVA material is 40%~55%. This material has high hardness and good elasticity, and is commonly used in the production of sports equipment, automotive parts, etc.
The hardness of EVA material during foaming is 55%~75%, and this material has higher hardness and better wear resistance.
In addition, the hardness of EVA is also related to its thickness, usually between 0.5-60mm in thickness and 25-80 degrees in hardness.
