Soft, closed cell PVC, foam. Watertight seal. Flame Retardant Grade
NORSEAL 2521 is a closed cell PVC foam with a very low density and a low force to compress.
NORSEAL 2521 is designed to create a watertight seal with a minimal amount of force. This ability allows it to conform easily to rough or irregular surfaces. It is also ideal for sealing thin gauge metals or plastics which could distort under greater pressures.
