Cel supplies different types of polypropylene honeycomb:
Polypropylene honeycomb without TNT (PP 8.80)
Polypropylene honeycomb with TNT (a thin thermo-welded sheet on both sides; PP 8-80 T30, PP8-120 T30)
Polypropylene honeycomb with TNT and a plastic film (thermos-welded on both sides; PP 8-80 T30 F75)
FIELDS OF APPLICATION
Polypropylene honeycomb, one of the core materials in sandwich panels, is bonded to different materials (aluminium sheets, high pressure laminate skins, marine plywood, fibreglass, etc.), and can be thermo-welded or glued to TNT or technical fabrics, which makes the production of sandwich and lightweight panels easier.
Polypropylene honeycomb is also used as flat surface for cutting tools (waterjet cutting machines).
Thanks to its chemical-resistance and its reliability in aggressive environments, polypropylene honeycomb can also be used as support for filters to reduce corrosive gas emissions.
