EVA (ethylene vinyl acetate copolymer) Block material is a high-performance material widely used in insoles and other products. Its hardness, density, shape and other parameters can be adjusted according to specific needs, allowing it to exert its unique advantages in different situations.
Parameters of EVA Block material
Hardness: The hardness range of EVA is usually between 20A and 70A. For insoles, softer EVA Block materials (such as 30A to 50A) are generally preferred because they provide better cushioning and comfort. Harder EVA Block materials (such as 50A to 70A) are more suitable for occasions that require stronger support and stability, such as sports insoles or orthopedic insoles.
Density: The density of EVA is usually between 0.3 and 0.9 g/cm3. For insoles, medium-density EVA Block materials (such as 0.5 to 0.7 g/cm3) are usually the best choice because they can provide sufficient support while maintaining adequate cushioning properties.
Shape: EVA Block material can be made into various shapes to suit different insole designs. Common shapes include rectangle, circle, oval, etc. The choice of shape depends on the specific needs of the insole, such as the need to provide more comprehensive support, more concentrated cushioning, etc.
Application of EVA Block material in insoles
Running insoles: For running insoles, you usually need to choose softer EVA Block materials (such as 30A to 40A) and medium density materials (such as 0.5 to 0.6 g/cubic centimeter). Such insoles can provide excellent cushioning properties and reduce the impact on the feet when running.
Basketball insoles: Basketball requires stronger support and stability, so it is suitable to choose harder EVA Block materials (such as 40A to 50A) and medium density materials (such as 0.6 to 0.7 g/cubic centimeter). Such insoles can provide enough support to help athletes keep their feet stable during rapid movements and changes of direction.
Orthopedic insoles: For users who need orthopedics, they can choose EVA Block materials with higher hardness and density (such as 50A to 60A, 0.7 to 0.9 g/cubic centimeter). Such insoles can provide stronger support and stability and help correct abnormal foot posture.
Advantages of EVA Block material
Cushioning performance: EVA Block material has good cushioning performance and can effectively absorb ground reaction forces and reduce the impact on the feet.
Support performance: By adjusting the hardness and density, EVA Block material can provide different levels of support to meet the needs of different users.
Comfort: EVA Block material is soft and comfortable, providing an excellent wearing experience.
Durability: EVA Block material has high durability and can withstand the wear and tear of long-term use.
Application of EVA Block materials in other products
In addition to insoles, EVA Block materials are also widely used in other products, such as:
Yoga mat: Choose softer EVA Block materials (such as 30A to 40A) and medium density materials (such as 0.5 to 0.6 g/cubic centimeter), which can provide excellent cushioning and comfort and are suitable for yoga practice.
Children’s toys: EVA Block material is safe, non-toxic, soft and resistant to falling, and is an ideal material for making children’s toys. EVA Block materials of different hardness and density can be selected to meet the needs of children of different ages.
To sum up, EVA Block material has a wide range of applications in insoles and other products due to its adjustable hardness, density, shape and other parameters. By rationally selecting parameters, insoles and products can be produced to meet different needs and provide users with excellent cushioning, support and comfort.
