Polypropylene honeycomb core NIDAPLAST 8RI

reinforcedlightweightrecyclable

Nidaplast 8RI is a polypropylene honeycomb panel engineered for infusion processes. It combines a lightweight, 100% recyclable PP honeycomb core with a thermo-welded polyester non-woven surface and a reinforced protective PP film under the non-woven to resist resin pressure and prevent cell filling during infusion.

Key technical and functional highlights

• Reinforced PP protective film (300 µm for the RI version) to withstand resin pressure and avoid cell filling during infusion.
• Thermo-welded polyester non-woven bonded to the honeycomb structure for reliable adhesion and optimal impregnation with thermosetting resins (polyester, epoxy…).
• Polypropylene honeycomb core: light (≈95% void), mechanically efficient and 100% recyclable.
• Available in large panels and multiple thicknesses to suit infusion and RTM applications.
• Certifications: DNV Marine Type Approval and Germanischer Lloyd, enabling marine and other demanding applications.

Applications

• Infusion processes with thermosetting resins (polyester, epoxy, etc.) for composite parts manufacturing.

Surface & manufacturing

• Surface: polyester non-woven thermo-welded to the cellular structure for controlled impregnation.
• Protective film beneath the non-woven: RI version uses a thicker PP film (300 µm) compared with standard Nidaplast 8 (50 µm), improving resistance to resin pressure.
• Manufactured in France under industrial quality standards.
