Plastazote LD45 Grey 3mm 1500x1000mm

Plastazote® LD45 Cross-Linked Closed Cell Polyethylene Nitrogen Expanded Foam - Grey 3mm 1500 x 1000mm. Tests show Plastazote® foam to be stable safe and non reactive when in contact with a variety of Museum objects. Plastazote® LD45 is most commonly used in the storage of museum objects but is only one grade in a wide range of Nitrogen expanded foams. Plastazote® foams are physically blown foams. They are the only products of their type which are expanded using pure nitrogen gas. This results in pure chemically inert foams with excellent physical properties. Foams made using solid chemical blowing agent systems always contain a significant amount of blowing agent chemical residues which can detract from the physical chemical and biological properties of the foamed polymer. Foams manufactured using volatile liquids can suffer from dimensional changes. Plastazote® foam contains no blowing agent residues.
