Polypropylene honeycomb core NIDAPLAST 8FR

for sandwich panelscompression-resistantrecyclable

Nidaplast 8FR is an extruded polypropylene honeycomb core that incorporates a halogen-free flame retardant designed to limit flame propagation (flammability rating: UL94 V2). Manufactured in France, it is intended for fire-retardant composite applications and sandwich panel fabrication.

Key product information:

• Function: Fire-retardant honeycomb core limiting flame propagation (UL94 V2).
• Material: 100% recyclable polypropylene with a halogen-free flame retardant in the honeycomb composition.
• Use: Fire-classified / flame-retardant composite core for sandwich panels and lamination, infusion (RTM) and bonding processes.
• Cell size: 8 mm.
• Surface treatment and assembly: Polyester non-woven (45 g/m²) thermo-welded onto the core for bonding/impregnation; plastic film (50 μm) beneath the non-woven to seal cells and reduce resin/adhesive consumption.
• Manufacturing origin: Made in France.

Dimensions and formats:

• Standard large panel size: 2500 × 1220 mm.
• Available thicknesses (heights):
  • 5 mm
  • 10 mm
  • 15 mm
  • 20 mm
  • 25 mm
  • 30 mm
  • 40 mm

Performance and physical data:

• Indicative surface weight for a 20 mm sandwich panel: 1.5 kg/m².
• Honeycomb density: 65 kg/m³.
• Compression strength: 1.2 MPa (equivalent to 120 tonnes/m²).

Applications / Additional notes:

• Designed to be bonded or impregnated with thermosetting resins (polyester, epoxy, etc.).
• Suitable as a flame-retardant core in sandwich panels for composites, lamination, infusion/RTM and bonding processes.
