In the field of insole manufacturing, EVA material is highly favored due to its excellent elasticity and cushioning performance. The hardness of EVA materials is one of the key factors affecting their performance and usage effectiveness. This article will focus on the difference between EVA40 degrees and 60 degrees, and analyze it from a professional technical perspective.
1、 Hardness difference
There is a significant difference in hardness between EVA40 degrees and 60 degrees. 40 degree EVA is relatively soft, with good elasticity and cushioning performance, which can provide better comfort and support. And 60 degree EVA is relatively hard, with good support and stability, which can provide better foot protection.
2、 Buffer performance
Due to differences in hardness, the buffering performance of EVA40 degrees and 60 degrees is also different. 40 degree EVA can better absorb and disperse the impact force on the feet, providing better cushioning effect. However, 60 degree EVA is relatively weak and cannot provide sufficient buffering and support.
3、 Durability
There is also a difference in durability between EVA40 and 60 degrees. 40 degree EVA is relatively prone to aging and has poor durability. 60 degree EVA has good durability and stability, and can withstand long-term use and wear.
4、 Applicable occasions
Due to the aforementioned performance differences, the applicability of EVA40 degrees and 60 degrees is also different. 40 degree EVA is more suitable for occasions that require high comfort and support, such as sports shoe insoles, indoor shoe insoles, etc. 60 degree EVA is more suitable for occasions that require high support and stability, such as outdoor shoe insoles, basketball shoe insoles, etc.
In summary, there are significant differences between EVA40 degrees and 60 degrees 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. At the same time, it is also necessary to pay attention to the environmental protection and sustainability of materials, and choose materials that meet environmental standards to reduce their impact on the environment.
