1.5mm Flexible 3-Ply Birch Plywood Sheet
SLEC 1.5mm Flexible 3-Ply Birch Plywood is a high-quality plywood sheet manufactured in Finland, offering an excellent balance of strength, flexibility and stability for precision modelling and woodworking applications.
Constructed from three layers of birch veneer, this lightweight plywood provides increased rigidity compared with thinner grades while maintaining excellent workability. It is ideal for model aircraft structures, model boat components, CNC routing, laser cutting and a wide range of precision hobby projects where accurate and consistent results are required.
This is BR grade Birch Plywood, similar in quality to B grade material, with knots limited to a maximum diameter of approximately 8mm. The surface is sanded to provide a smoother finish than many standard plywood products, making it suitable for both structural and visible model components.
The plywood is bonded using Phenol Glue EN314-2 Class 3, providing an exterior-grade bond for increased durability. This makes it suitable for applications where additional strength and stability are required.
Suitable for both laser cutting and CNC machining, this plywood produces accurate and consistent results for model parts, formers, ribs, bulkheads, custom components and precision-cut designs. When laser cutting exterior-grade plywood, a darker burnt edge may be produced due to the adhesive used during manufacture. This can be removed by light sanding if required.
This material is PEFC certified, supporting responsible forest management and sustainable timber sourcing.
