Rubber sponge polyurethane foam for shockproof or sealing.
Force always acts on articles in any circumsance, and possibly damages them. In order to reduce the influence of external force, these shock-proof types of material are introduced in. What's more, these sponges have excellent weatherability, temperature endurance, aging resistance and damping-sealing.
