Polyethylene foam or PE foam is
created by the extrusion of polyethylene resins mixed with a blowing
agent to create the closed cell sheets, rolls, and shapes this product
is known for. Having closed cells allows much higher load bearing and
resistance to being crushed by heavy objects. PE foams are flexible and
come in several densities and colors. PE foams are resistant to many
industrial chemicals, retain color, are UV resistant, waterproof, and can
be cut mechanically or with heat. PE foams do not break apart easily and
can handle repeated drops without losing shape and protective
attributes. This product can also be recycled.
Crosslinked PE foams have most of the same
attributes as regular extruded PE but with a much finer cell structure.
Crosslinked PE also comes in many density ranges. Colors are generally
deeper and the sheets have a smoother finish while generally more
resilient than the same density PE planks and sheets. Versions of this
product are found in many athletic and leisure products because of its
aesthetics and improved thermoforming characteristics.
