Both microcellular polymer and microcellular rubber are materials that can be utilized in the production of shoes. There are some distinctions between the two, though
Specifications:
1. Composition: While micro cellular polymer is comprised of a range of materials, such as polyurethane, EVA (ethylene-vinyl acetate), and other synthetic materials, micro cellular rubber is made of natural or synthetic rubber.
2. Density: Micro cellular rubber has a higher density than micro cellular polymer, suggesting that it might offer superior support and durability. It may, however, also be less comfortable and heavier.
3. Flexibility: Micro cellular polymer can be more relaxing and simple to wear than micro cellular rubber since it is generally more flexible. It might not, however, provide as much support as microcellular rubber.
4. Breathability: Both materials are breathable, but because micro cellular polymer can be produced with precise air channels or perforations, it might be able to keep the feet dryer and cooler longer.
5. Cost: Compared to micro cellular polymer, which can be produced from less expensive synthetic materials, micro cellular rubber is often more expensive, however this can vary based on the type and quality of rubber utilized.
In conclusion, micro cellular polymer is typically more flexible, lightweight, and breathable than micro cellular rubber, which is denser, more supporting, and more lasting. The intended usage of the footwear, personal preferences, and budgetary constraints may all influence the decision between the two.
