Final product types

• Running shoe midsoles
• Work boot and safety shoe outsoles
• Sports insoles
• Protective paddings and shin guards

3. Medical Device Housing and Tubing

Medical device firms select this elastomer for single-use and reusable product casings, connectors, and low-pressure flexible tubing.
