Practically this means closed cell foams will not absorb significant amounts of water or other liquids, which is great for buoyancy and for seals and gaskets.Ĭontrarily, open cell foams will absorb and hold water.įoam rod and tube is also available, but is limited in availability – please check with the sales office.įoam availabe to buy online is listed below. In this case when you squeeze the foam you expel all of the gas from the structure, but when you release it (like a sponge) it sucks air back into the structure In open cell foams both the gas and the plastic are continuous phases.In closed cell foams the plastic is the only continuous phase (this is like having millions of small bubbles of plastic all bonded together) and therefore the gas in the foam is trapped inside the bubbles.Note: Foam sheet is classified as either closed cell or open cell: In most cases we offer the option of adding a self-adhesive finish to one or both sides of the foam sheet.įurthermore, .uk has the facility to convert many of these materials to foam gaskets & washers to your requirements. + quoted sizes are an indicative guide only *subject to confirmation and availability at time of enquiry Plastazote® Low Density Polyethylene - Metallocene Resin foams (including MP15, MP24, MP33, MP45)įoam is generally available in sheets of approx 2000mm x 1000mm+ (or cut to size*) - and we also offer a fabrication service to laminate, cut, and glue our range of foam sheet to your specific requirements.By filing blocks of Styrofoam with special tool I made using lots of roofing tacks, I was able to make a supply of pea size particles.Using a soupy cement and water mix, I got the particles wet with the minimum amount of the mix needed to keep them stuck together.
