PP honeycomb core material NIDAPLAST 8FR

fire-resistant

The nidaplast 8FR is an extruded polypropylene honeycomb with an approved halogen-free material that limits the spread of flames. (flammability according to UL94 standards: V2 classification) Nidaplast products are polypropylene honeycomb intended to serve as a core for structural sandwich panels. The nidaplast 8FR is an extruded polypropylene honeycomb with an approved halogen-free material that limits the spread of flames. (flammability according to UL94 standards: V2 classification) Nidaplast products are polypropylene honeycomb intended to serve as a core for structural sandwich panels. Halogen-free material that limits the spread of flames Large sandwich panel: 2500 x 1220 mm Different thicknesses: from 5 to 40 mm Cell size: 8 mm Indicative surface mass for a 20 mm sandwich panel: 1.5 kg / m2 Nidaplast 8FR honeycomb products are fire retardant materials and are also flame retardant composite materials The honeycomb has a density of 65 kg / m3 which allows good resistance to impact and compression. The compressive strength of Nidaplast 8FR is 1.2 Mpa (120 Tons / m2) The polyester nonwoven (45 g / m2) present on the nidaplast honeycomb cores offers an ideal surface for bonding or impregnation with thermosetting resins (polyester, epoxy, etc.). The thermo-welding of this nonwoven on the honeycomb structure ensures it a perfect grip. The plastic film (50 μm) placed under the nonwoven makes the cells waterproof and limits the consumption of resin or glue. The honeycomb is made of polypropylene, a durable and 100% recyclable material. For the nidaplast 8FR product, the material used in the composition of the honeycomb is a flame retardant, without halogen.
