Plastazote foam gaskets

Plastazote foam is a synthetic cross-linked, closed-cell polyethylene foam made using crude oil into which nitrogen is blown which expands the foam.  This manufacturing process produces a flexible and tough material.  When the plastazote foam has compressed each nitrogen-filled cell acts like a balloon, causing the foam to return to its original shape.


Being of a closed-cell structure, plastazote is impenetrable to air and moisture and will not allow liquids to pass through or be absorbed making it an excellent choice for gasket production.  Plastazote foam gaskets are generally placed between two surfaces to create a low-pressure seal preventing the leakage of liquids or gas and the intrusion of dust and debris when under compression.


Plastazote, like other polyethylene foams, is manufactured in a range of densities for use in different applications.
