The Short Answer
Particle board is 15-20% cheaper and lighter. Use it for TV cabinets, wardrobes, and dressers in standard guest rooms. MDF gives you a smoother edge and better moisture resistance. Use it for headboards, desk tops, and anything that gets painted. Both work fine — the decision is project-specific.
Particle Board: Where It Works
We use particle board on about 70% of our orders. It's dimensionally stable, holds screws well, and comes in at 680 kg/m³ for 18 mm board — lighter than MDF at 745 kg/m³. Three thicknesses in our shop: 15 mm for lightweight cabinet backs, 18 mm standard for bodies and shelves, 25 mm for heavy-duty tops and long-span shelving. All our particle board carries CARB P2 or E0/E1 certs — we batch-trace every run back to the mill.
MDF: When to Upgrade
MDF costs more per sheet, but we push it for three situations: headboards (the edge takes paint without showing grain), open shelving where both sides are visible, and humid markets — coastal hotels in Southeast Asia, resort properties in the Middle East. MDF's face resists moisture better than particle board. But the edges still need good banding. If moisture is a real concern, we suggest 2 mm PVC edge banding regardless of board type.
The Edge Banding Trap
The board itself matters less than how you seal the edges. Cheap edge banding — thin PVC, poorly applied — fails within a year in a hotel room. Housekeeping mops, bathroom humidity, cleaning chemicals all attack exposed edges. We run automatic edge banders with pre-milling. The machine shaves the board edge clean before applying tape, so there's no dust pocket between board and banding. Weekly peel test: minimum 3 N/mm per EN 311. We stock 100+ RAL and NCS color references. Color match turnaround: 2-3 days with a physical reference.
