Most PVC formworks on the market warp under the sun, crack in winter, and fail after a few pours. The reason is almost always the same: unqualified materials+calcium powder. We do it differently: our PVC plastic board formwork is made from 100% virgin UPVC - over 95% of the formulation, with 0% recycled content and 0% calcium powder.
✅ 50+ reuses — one panel replaces 5–10 plywood panels
✅ No sun warping — stays flat under direct sunlight, no S-shape or U-shape deformation
✅ No winter brittleness — stable from -25℃ to +70℃, no cracking in cold weather
✅ Excellent nail-holding — nail within 2 cm of the edge without cracking; re-nail the same hole multiple times
✅ Waterproof & moisture-proof— can be stored outdoors in rain, no swelling
✅ No release oil needed — smooth, non-stick surface releases cleanly with just water+mop
✅ Flame retardant — inherent fire resistance from virgin UPVC
Cheap formwork looks the same on day one. The difference shows up on pour ten, or the first winter, or the first time it sits under direct sun. What price, what goods. Don't pay attention to low costs only. Let's discuss more about the quality distinguish: [email protected]; +86 17806112299(WhatsApp); https://www.sdjingfang.com/Slab/1977.html
