Formwork System Phenolic Film Faced Plywood with WBP Glue boiled 72hrs
Film Faced Plywood refers to the plywood film faced with film. The film covered on both side of plywood and after hot pressed in order to make sure the plywood a smooth surface, bright gloss, waterproof, fireproof, and excellent durability (weather resistance, corrosion resistance, chemical resistance) and anti-fouling ability.
Using film faced plywood to make the concrete surface smoother, which can easier dismantle the formwork and avoid secondary dusting, greatly improving work efficiency and saving manpower and materials.
Film faced plywood can be used with formwork as a slab formwork system components or wall formwork system components, and is more often used for unregular slab parts. This kind of coated plywood can be used for slab formwork that does not require concrete surface effects. High temperature resistant waterproof glue is usually used. The wood species can be poplar or hardwood. The phenolic resin coating of about 120-200g/m² is variously used on both sides. The conventional size is 4′x8′ and the thickness is 9-21mm.
Construction Film faced plywood is phenolic film faced plywood which up to 25 times reuses with a wide range of thicknesses and sizes.
Specifications
Construction film faced plywood normally use poplar core, hardwood core or combi core, the phenolic film on both side can be black or brown, glue is WBP. Sealed edges.
Surface
Construction film faced plywood coating weight is 120-200g/m2 both sides.
Face and reverse: Brown phenolic film combination or Black film combination or Anti-slip film.
Edge sealing: Water resistant paint edge sealed.
Panel size
Size: 600/1200/1220/1250 mm x 1200/2400/2440/2500mm
Thickness: 9-21mm
Glue type
Melamine+Phenolic 24 hours boil test glue.
WBP Phenolic 72 hours boil test glue.
Tolerances
Thickness tolerances: +/-0.5
Other tolerances:
The panel can have more or less dimensional changes due to changes in the air humidity.
End uses
Usage mainly for slab forms/install flooring/vehicle.
Typical number of reuses for slab forms is likely to be about 5 -25 times.
However, the number of reuses will depend on a wide range of factors including good site practice, the required concrete finish, careful handling & storage of forms and the type and quality of release agent.

QC of Plywood
Construction attaches great importance to the maintenance of product quality. Each piece of plywood is supervised by specialized personnel from the selection of raw materials, the specifications of glue, the layout of the core board, the high-pressure laminating veneers, the laminating process, including the selection of the finished product. Before large packaging and loading cabinets, our inspectors will check every piece of plywood to ensure that all products and processes are 100% qualified.
