A cellular plastic with a coarse-cell structure and a rough surface on both sides.
The material has a closed-cell structure and is well-suited for use as condensation, air, and thermal insulation in recreational products, as packaging, and for shock absorption.
A common application for cellular plastic is thermal insulation, where the material performs very well. Its thermal conductivity of 0.040 W/mK makes it an excellent thermal barrier that keeps the cold out and the heat in—or vice versa.
Durable materialProtective materials for packaging and other products
GC cellular polyethylene is an ideal choice for packaging where the material must withstand significant stress. The material is cross-linked, which makes it highly resistant to tearing and tensile stress. When packaging heavier items, the material is available in a higher density to prevent the cell structure from being damaged.
Lower-density material is flexible and bendable, while higher-density material feels rigid and stiff.
The coarse-celled surface is less delicate than that of other cellular plastics, where the surface is easily cut by sharp edges and repeated use.
When used as packaging, the material can be reused for multiple cycles.
Although there are more cost-effective cellular plastics for packaging, this is a good option because you can reuse the material many more times before it needs to be replaced and repurchased.
Well-known products made from this material include packaging, filler material, knee pads, roof profiles, thermal insulation for cabinets and ventilation products, gaskets, and sealing strips.
