Quick Answers

Is melamine the same as phenolic?
No. They are different adhesive chemistries. Melamine glue is melamine-urea-formaldehyde (MUF) resin, water-resistant under normal use, EN 314 Class 2 / EN 636-2. Phenolic glue is phenol-formaldehyde (PF) resin, fully cross-linked and water-insoluble, EN 314 Class 3 / EN 636-3. Both are used in real fit-for-purpose film-faced plywood; they sit at different points on the cycle-count and exposure envelope.
Is phenolic film-faced plywood always better than melamine?
No. Phenolic is the right call for long-cycle infrastructure work, exposed sites, or jobs that explicitly call for EN 636-3. Melamine is the right call for short-cycle programs (8 pours or fewer), covered slab forming, and budget-controlled work where the spec is EN 636-2. Buying phenolic for a 6-cycle job is overspending — you pay for cycles 9-20 you never run.
What is the disadvantage of melamine film-faced plywood?
Melamine-glued panels are EN 636-2 / Class 2: they handle humid, ventilated environments and short reuse cycles well, but they degrade fast when exposed to standing water, when edges aren't sealed, or when panels sit assembled across a wet weekend. The realistic envelope is up to 10-15 cycles under disciplined site conditions, dropping faster under rough handling. Use them where the application stays inside that envelope.
Can phenolic film-faced plywood be reused?
Yes. Phenolic-glued panels with a heavy phenolic film face deliver up to 20 reuse cycles when stripped within the post-pour window, edges sealed before the first pour, stored flat off the ground, and not abused at the edge with crowbars. On a real site with mixed crews and midweek weather, expect 60-80% of the catalogue figure — bid the program against the realistic number.
How many times can melamine film-faced plywood be reused?
Catalogued reuse for melamine-glued panels with a heavy phenolic face film is up to 10-15 cycles. Field performance typically lands at 60-80% of the catalogue figure depending on site discipline. Form Extra (Vinawood) reaches the higher end of that range thanks to a heavier film overlay and tighter veneer grading, while still being EN 636-2 — the higher cycle count comes from the face system, not the core adhesive.
