EPDM vs. Ebonite
What's the Difference?
EPDM and Ebonite are both types of rubber materials commonly used in various applications. EPDM, or ethylene propylene diene monomer, is known for its excellent weather resistance and durability, making it ideal for outdoor use. On the other hand, Ebonite is a hard rubber material that is often used in the manufacturing of musical instruments, such as clarinets and bagpipes, due to its ability to produce a rich and resonant sound. While EPDM is more flexible and resistant to harsh environmental conditions, Ebonite is harder and more rigid, making it suitable for specific applications where durability and sound quality are important.
