NORNS polypropylene honeycomb core is a high-performance thermoplastic core material engineered for sandwich panel applications.
Fabricated from polypropylene (PP), its tubular honeycomb structure delivers an optimal balance of low weight, stiffness and impact resistance.
This material fits a wide range of composite applications requiring weight reduction, durability and moisture resistance.
| Property | Description |
|---|---|
| Material | Polypropylene (PP) |
| Structure | Tubular Honeycomb Core |
| Cell Type | Circular Tube Structure |
| Color | Natural / Customizable |
| Recyclability | 100% Recyclable Thermoplastic |
Every PP honeycomb core is defined by cell size and density. All grades are available bare, tissue-laminated or film-faced.
| Product Grade | Cell Size (mm) | Density (kg/m³) | Thickness (mm) | Cell Geometry |
|---|---|---|---|---|
| PP6 Series | 6 | 70 – 150 | 5 – 100 | Tubular |
| PP8 Series | 8 | 70 – 150 | 5 – 100 | Tubular |
| PP10 Series | 10 | 70 – 150 | 5 – 100 | Tubular |
| PP12 Series | 12 | 70 – 150 | 5 – 100 | Tubular |
Full model code = PP + cell size + nominal density + optional surface suffixes. Example: PP8-80-T30-F. Core thickness is specified separately. Custom cell sizes, densities and thicknesses are available on request.
Example: PP8-80-T30-F = 8 mm cell, 80 kg/m³ density, 30 g/m² tissue, PP film faced. Custom density, thickness and cell size available on request.
NORNS supplies a broad portfolio of PP honeycomb core grades in varied thicknesses and densities to satisfy diverse sandwich panel and lightweight composite requirements.
