Moso bamboo, 4–5 years old
Raw bamboo comes from FSC-certified plantations within 80 km of our factory. Moso bamboo (Phyllostachys edulis) is harvested at 4–5 years old — the optimal age for fibre density and stiffness. Younger culms lack strength; older culms become brittle.
- 80 km average transport distance (truck)
- FSC-certified plantation partners (8 growers)
- Harvest cycle: November – March (best starch content)
- Annual feedstock: 200,000 tonnes green culm
Strand geometry matters
After debarking, culms are chipped into long strands (~75 mm × 25 mm × 0.7 mm). Strand geometry is the single biggest determinant of final panel MOR/MOE. Our in-line optical QC continuously monitors strand dimensions and rejects off-spec material automatically.
- Strand dimensions: 75 × 25 × 0.7 mm (target)
- Optical QC rejects ~3% of off-spec strands
- Drying: rotary drum dryer, 180°C inlet, 3% MC outlet
- Throughput: 8 tonnes/hour per line
PF resin, E0 / CARB compliant
Dried strands are blended with phenol-formaldehyde (PF) resin in a continuous blender. PF was chosen over MDI or UF for its combination of moisture resistance, zero formaldehyde off-gassing, and compatibility with structural applications. No urea-formaldehyde (UF) is used — that's why BAMOSB is E0 / CARB Phase 2 by default.
- Resin type: Phenol-formaldehyde (PF)
- Resin loading: 6–8% (depending on product)
- Wax emulsion: 1.0% (moisture resistance)
- Formaldehyde off-gassing: ≤ 0.3 mg/L (E0)
200°C, 35 bar, 4 minutes
Resinated strands are scattered onto a forming line in three layers (face / core / face) with strand orientation aligned for cross-directional strength. The mat enters a continuous press at 200°C and 35 bar for ~4 minutes, exiting as a 1.22 × 2.44 m panel at 18mm thickness.
- Press temperature: 200°C
- Press pressure: 35 bar
- Press cycle: 4 minutes (18mm)
- Panel dimensions: 1220 × 2440 mm (custom up to 2500 × 7500 mm)
3 in 1,000 reject rate
Panels are cooled for 24 hours to ambient, then sanded to calibrated thickness tolerance (±0.2 mm). Every panel passes through our QC lab for density, MOR/MOE spot-checks, IB, thickness swell, and formaldehyde. Reject rate is ~0.3% (industry average: 1.5–2%).
- Thickness tolerance: ±0.2 mm
- Density target: 660–700 kg/m³
- 100% of commercial batches QC-tested
- Annual third-party audit by SGS
