100% recycled PET foam core sheets available here in 4 thicknesses. This material is used extensively in wind turbine production as well as many more areas. Its benefits include high strength to weight ratio, thermal stability and insulation as well as acoustic insulation properties. Please see technical data sheet below for full information.
ArmaFORM PET core will work with almost all kinds of resin and adhesive systems. The only main exception is with 1-component moisture curing adhesives (such as white PUR wood glue) as ArmaFORM PET core is closed cell and very diffusion resistant so moisture cannot diffuse in or out of the adhesive thereby preventing proper curing.
