Birch FSF plywood is a multilayer panel made from natural birch veneer bonded with a phenol-formaldehyde adhesive with increased moisture resistance.
The material retains its strength and shape when used in high humidity conditions and under load, making it suitable for construction and industrial applications.
Applications
- construction and finishing works, including high-humidity environments
- urniture and cabinet manufacturing
- transport and industrial equipment
- formwork, packaging, and pallets
- structures operating in high humidity conditions
