Expanded Polyethylene (EPE) is a closed cell non-cross linked PE Foam product which is a produced using low density Polyethylene resins with HCFC & CFC free gasses. Along with being a lightweight material, EPE Foam is also non-abrasive and chemically inert, water resistant and environmentally 100% recyclable.
EPE is used extensively in the marine industry for marine buoyancy. EPE displays all of the characteristics required to be deemed to satisfy as LDFM Type Foam.Here is the link to the buoyancy section of the National Standard requirements. Pages 82-86 is the section on buoyancy requirements. It is the perfect product for increasing buoyancy in alloy boats. Please note, suppliers quoting the marine buoyancy foam approvals under NMSC / National Register of Compliant equipment are no longer current or approved under AMSA. EPE is a product is classified as a buoyancy LDFM Type A Foam without the requirement of AMSA approval.
Sheet size is 2000 x 1000 x 50 mm. It can be cut to size using a sharp blade or jigsaw.
We also sell other products that display excellent buoyancy properties such as polystyrene and rigid polyurethanes. For boats that are not made from alloys, we also have liquid 2 part polyurethane kits which can be used to fill a cavity.
