A cellular plastic with a fine-celled surface structure. The material has closed cells, making it impervious to moisture and air. Cellular polyethylene is extruded as a roll material with a skin on both sides and is ideally suited for gaskets and seals where the requirements for compression and environmental conditions are not overly demanding. Cellular polyethylene is widely used for sealing strips in pre-cut lengths and as a roll material.
The material is also suitable for use as condensation and thermal insulation in HVAC equipment and plumbing products. The cellular plastic comes in gray as the industry standard, to discreetly insulate sheet metal products, and in white to similarly and discreetly seal white plastic products. The material is also available in other colors, although white and gray are the most common.
Durable materialResistant to tearing and tensile stress
Cellular polyethylene is cross-linked and is therefore more resistant to tearing and tensile stress than other non-cross-linked cellular polyethylenes. In English, the term is “cross-link,” a process in which polymers and molecular chains are bonded together to create a more durable material.
The material has a wide temperature range, withstanding temperatures from -80° to 100°, and holds several fire rating certifications, including FMVSS 302, DIN 4102-1, and UL94 BHF/HF2.
Cellular plastics are generally clean and environmentally friendly materials that do not release hazardous substances when incinerated.
