EVA is a thermoplastic elastomer material with excellent elasticity and cushioning properties. In the field of insole manufacturing, EVA material is widely used in the production of various insoles. However, there are certain differences in the performance and application of EVA materials with different hardness. This article will focus on the difference between 60 degree EVA and 45 degree EVA.
1、 Hardness difference
The hardness of 60 degree EVA is significantly higher than that of 45 degree EVA. This means that 60 degree EVA has better support and stability, providing better foot protection. 45 degree EVA is relatively soft and more suitable for insoles that require more comfort and softness.
2、 Buffer performance
Due to differences in hardness, the buffering performance of 60 degree EVA and 45 degree EVA also differ. 60 degree EVA can better absorb and disperse the impact force on the feet, providing better cushioning effect. However, 45 degree EVA is relatively weak and cannot provide sufficient buffering and support.
3、 Durability
60 degree EVA has good durability and stability, and can withstand long-term use and wear. However, 45 degree EVA is relatively prone to aging and has poor durability.
4、 Applicable occasions
Due to the aforementioned performance differences, the application scenarios of 60 degree EVA and 45 degree EVA are also different. 60 degree EVA is more suitable for occasions that require high support and stability, such as sports shoe insoles, outdoor shoe insoles, etc. 45 degree EVA is more suitable for occasions that require more comfort and softness, such as indoor shoe insoles, slipper insoles, etc.
In summary, there are significant differences between 60 degree EVA and 45 degree EVA in terms of hardness, cushioning performance, durability, and applicability. When selecting insole materials, it is necessary to comprehensively consider specific needs and usage scenarios, and choose appropriate hardness values and materials.
