Description
Plastazote® is a closed cell, cross-linked polyethylene block foam manufactured using Zotefoams unique production process. This process, unlike other foam making processes, only uses nitrogen for foam expansion, therefore no CFCs, HCFCs, HFCs or volatile organic compounds (VOCs). The process used creates unparalleled purity, isotropic consistency and closed cell protection. These qualities combined make Plastazote® the foam of choice for use within the heritage sector for both archiving and packing.
