Our PE foam sheets is a closed cell polyethylene foam blown with nitrogen. We uses Plastazote LD 29 and LD 45. In contrast to other foams, it is tough and flexible, defined by the regular shapes, sides and walls of the cells made from polyethylene. If Plastazote foam is squashed and compressed, each nitrogen filled cell acts like a balloon and the foam bounces back to its original shape. Applications include floatation, matting, presentation boxes, tool storage, insulation, tool trays, etc. We offer Plastazote Foam Sheets in many different thickness and densities. Plastazote foam is great foam for archival and museum storage purposes. Zotefoam plastazote Can be easily shaped, cut and bonded to other materials, Non-toxic, odourless, will not absorb water and is buoyant. Can be washed, disinfected and wiped clean and excellent chemical resistance to most oils, solvents, acids & alkalis. Plastazote is weatherproof and has good ultraviolet stability. Durable, tough and flexible and recovers repeatedly from impacts and very good thermal insulator.
