FORMWORK PLYWOOD

Formwork plywood is made by putting a film coating on both sides following the WBP glue-assisted pressing of all the wood veneer plywood layers. As a result, the board has a smooth, shiny, and durable surface that can be used in construction. The most common types of wood are eucalyptus, rubber wood, and acacia.

Technical specifications:

Size: 1220*2440 mm (4*8 ft)
Thickness: 12mm up to 18mm
Thickness tolerances: ± 0.5mm
Glue: 100% WBP (Water Boiled Proof) – Phenolic
Reuse: ≥ 10 times
Film: Stora enso, brown
Screw holding force: 148.0 N/mm2.
Moisture absorption: 9.7%.
Swelling of the thickness soaked in water for 24 hours: 2.1%.
The force of pressing the board: about 100 – 120 tons/m2.
Usage: For construction formwork

Composition:

There are mainly two kinds of glue:

WBP glue (Water Boiled Proof) has water-resistant, is suitable for use outdoors in humid environments without delamination. WBP melamine and WBP phenolic glue boards are common types.
Moisture Resistant glue, often known as MR glue, is frequently used inside due to its moisture-proof qualities and suitability for low-humidity conditions.

The covering, which serves to generate smoothness, lessen scratches, and protect the board while in use, is made of water-resistant phenolic bonded paper.

The hardness, longevity, and bearing capacity of plywood are all determined by its core.
