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.

Sampmax Construction Film faced plywood is phenolic film faced plywood which up to 25 times reuses with a wide range of thicknesses and sizes.

QC of Plywood

Sampmax 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.
