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.

Common questions about Insulogy by Paramount XPE/XLPE
What is the difference between XPE and XLPE foam?
They are the same material described two ways. XLPE is the general name for cross-linked polyethylene foam, and XPE is the chemically cross-linked route to it, where a cross-linking agent and a foaming agent are extruded and foamed continuously at high temperature. IXPE is the alternative route, cross-linked by electron beam instead of chemistry, which gives a finer cell and lets us go much thinner.
What density should I specify for my application?
Our XPE runs from 25 to 120 kg/m3, set by the foaming ratio. Lower densities around 28 to 33 kg/m3 give the softest hand and the best thermal numbers, down to 0.034 W/m.K, which suits duct wrap and under-deck insulation. Higher densities from 100 to 125 kg/m3 give tensile strength above 0.9 MPa and Shore hardness in the 50 to 60 range, which is what gasketing and structural cushioning need. Send us the duty and we will recommend the ratio.
What thickness and width can you supply?
Single layer runs 2 to 12 mm, and laminating takes that up to 100 mm. Maximum width is 1600 mm. Anything wider than a single web is produced as a laminated build-up.
Do you supply flame-retardant, ESD, or antibacterial grades?
Yes. Conductive, ESD, antibacterial, flame-retardant, and UV-resistant variants are all available on the same base foam. Tell us which standard you are being held to and we will quote the matching grade.
