Cell Damper

CELLDAMPER is a foamed Polyurethane Elastomer developed for anti-vibration material to reduce oscillation. It is used in various fields from its superior anti-vibration performance which was not able to achieve with the traditional foam.

In order to meet our customer requirements there are 4 types and enable to fabricate into various thickness and dimensions.

1. Good anti-vibration
2. Low compression set
3. Non-silicone, Non-sulfur, Non-halogen
