Insulogy by Paramount XPE/XLPE
Our flagship XPE foam is produced from low-density polyethylene resin with a cross-linking agent and a foaming agent, foamed continuously at high temperature for a uniform closed-cell structure. The result is chemically stable, odourless, and flexible, and resists decomposition over a long service life. In a single material it delivers thermal insulation, waterproofing, and sound control, along with shock absorption and thermal-forming capability, which is why it is specified across HVAC and air conditioning, automotive, defence, building and construction, sports and leisure, shoes, and mats.
