Plastazote LD45 is a closed-cell, cross-linked polyethylene foam sheet supplied as a 2000 x 1000 mm sheet. The nitrogen cells inside the polyethylene make it lightweight, odorless, water-resistant and buoyant, and give it strong resistance to oils, solvents, acids and alkalis. It is firmer and tougher than open-cell foam and recovers from repeated impacts, which suits insulation, packaging and impact-absorbing padding. It cuts, saws, routes, thermoforms and heat-laminates cleanly, so it works for both workshop fabrication and one-off projects.

Plastazote LD45 is a closed cell, cross-linked polyethylene foam supplied as a sheet. Its structure is a large number of nitrogen cells held within the polyethylene. The foam is lightweight and completely odorless. It does not absorb water, so it is buoyant.
Because it is polyethylene, the foam resists most oils, solvents, acids and alkalis. Closed cell foams are usually harder, firmer and tougher than open cell foams, and much less springy. Each cell acts like a balloon, so the foam recovers from repeated impacts and returns to its original shape.
The foam can be thermoformed, sawed, laser cut, routed on CNC machinery and shaped with water jet equipment. It is also easy to split and heat laminate. Common uses include insulation, packaging, impact-absorbing sportswear and casing inserts.
