Closed cell cross-linked polyethylene (PE) foam

16.06.2021

A chemical cross-linked foam forms a resistant surface. Cross-linked closed cell polyethylene foam means that during cross-linking, the molecules connect by chemical bonds, forming a structure branched from the straight carbon chain, thus creating a more durable structure. The fineness of the cellular structure gives the material even greater stability.

It is also available in fire retardant and conductive variants: the cross-linked polyethylene foam is much more widely used than extruded PE foam. This is also due to the fact that it withstands the rigours of weather, and the cross-linked foam does not react with most chemicals, and is not vapour-permeable. Thus, it can be used to produce a durable insulating material, as it is not consumed by insects or rodents. Its vibration damping effect is particularly high.

Use:

• as a polyolefin insulation material in the automotive industry, mechanical engineering and architecture (due to its good heat, water and sound insulation)
• due to its vibration damping and absorbing effect, it is also be used to make mattresses and shoe soles
