's softness allows for deflection required for shock absorption and vibration damping, providing excellent cushioning and vibration damping performance.
is highly resistant to ozone, UV rays, and chemicals, making it possible to use in a variety of locations. In addition, performance is maintained even after repeated compression.
's properties show little change in the -40℃(-40℉) to 200℃(392℉)range, providing stable performance.
On top of the unique combination of excellent features, also works as a reliable foundation for additional functions and for enhancing performance without compromising the merit softness brings.
's composition makes it harmless to the human body and to the environment, causing no allergies when touched, and emitting no harmful gases when burned.
