Core material specialist 3A Composites Core Materials (Sins, Switzerland) featured on its JEC Europe 2013 stand two products that came on the market in 2012 and, since then, have been fine-tuned. The first is SealPerf, a technology that consists of thermally sealed holes arranged in a regular square pattern on the surface of a foam core. When it is applied to 3A’s AIREX T90 and T92 polyethylene terephthalate (PET) foam core, it provides a smooth hole surface that minimizes resin absorption and, thus, improves flow. 3A says that contrary to conventional wisdom about drilling holes in thick substrates, this technology can be applied without limitations to all sheet thicknesses. 3A also emphasized BALTEK Banova, a customizable veneer-based balsa material that can be used as core material and as a standalone panel in plywood applications.
