Aluminum foil thermal insulation foamAluminium foil thermal insulation foam is a laminate: a polyethylene foam core with one or more layers of aluminium foil bonded to one or both faces. The two layers act on…
Foamed plasticWhat separates one foamed plastic from another is not only the material but the forming route. Extrusion produces continuous sheet and roll, injection moulding produces one…
XPE Crawling MatAn XPE crawling mat is a play surface for infants and toddlers, made from cross-linked polyethylene foam. It is used in homes, in early-learning centres and in kindergartens, and…
Foamed materialFoamed material is a solid that has been expanded with gas. A blowing agent is dispersed through a polymer — or through a metal, ceramic or glass melt — and then made to release…
How many materials are there in insulation foamInsulation foam is not one material. The term covers several distinct families, and the number that matters is not how many exist but how many are a realistic option for the job…
What is insulation foam made ofInsulation foam is a cellular material that slows the movement of heat by holding gas inside a solid structure. What it is made of decides everything about how it behaves: how…
PP foam“PP foam” is not a product. It is a family name, and a supplier quoting it may mean a bead-moulded EPP part, an extruded uncross-linked PP sheet, or an irradiation cross-linked…
What is IXPE materialIXPE is irradiation cross-linked polyethylene foam. It uses the same base resin as XPE; the only difference is the energy that joins the molecular chains. XPE relies on a peroxide…
What is the difference between IXPE and XPE?IXPE is irradiation cross-linked polyethylene foam. The sheet is passed under an electron beam; the energy breaks carbon–hydrogen bonds, and the free radicals that result bond…
What is foam made ofA foam formulation comes down to three things: a base material, a blowing agent, and cross-linking. The base material is the polymer the cell walls are made of, the blowing agent…
XPE foam safetyIs XPE foam safe? The material itself carries no hazardous additives, and the safety questions that do come up — fire behaviour, residue, what it releases indoors — each have a…
XPE foam insulationXPE foam insulates because of its cell structure rather than because of any additive. The closed cells trap gas in place, the polymer cell walls conduct heat slowly, and the…
