SAINT-GOBAIN K20-0.7mm-MD

SAINT-GOBAIN K20-0.7mm-MD is 0.7mm thickness black color polyurethane foam.
Extremely low compression rebound force without PET backing. This unique concept provides additional sealing compression properties for the foam over a wider compression range.
This foam has a high surface energy and exhibits self-adhesiveness during the sealing process. It is an ideal LCD sealing material for handheld devices.
