Plywood is produced from the birch
Formaldehyde emission class Е-1,
Sanded (S2S), except grade IV/IV and the thickness from 21 mm.
Birch interior plywood - a high-quality construction material which has high strength and moisture resistance.
Interior plywood is easy to process and combines perfectly with the finishing materials. It withstands moisture, however, it is not recommended to use it for external works. The optimal scope of this material - indoors.
The most significant characteristic of plywood of FK brand - it is moisture. Choosing the required grade of plywood you need to determine where you are going to use it.
The fundamental difference between water resistant and waterproof plywood that is water resistant plywood glued using silicate glue which loses its stability in contact with water. Waterproof plywood, glued with a special moisture-resistant glue based on fenolic resin.
Water resistance interior plywood | properties
Water-resistant interior plywood has a visually pleasing texture, used for furniture. This kind of plywood is easily machined may be laminated to improve the aesthetic characteristics, strength, has excellent environmental performance.
Humidity of interior plywood is between five and ten per cent, the average water resistance. This sort of plywood is tested to determine tensile strength, by cleaving, when static bending of fibers, moisture, free formaldehyde emission. By the number of layers the product is an even number and an odd number. General purpose plywood veneer has an odd number. Special plywood has an even number of layers. Multi-layer plywood is considered, having five or more layers. Dimensions of interior plywood , as well as the thickness of the layers can range from 3 to 40 mm.
Advantage:
• 100% birch veneer
• Exceptional strength and durability
• The hardness of the surface
• Unique ability to withstand a heavy load
• Moisture
• Resistant to temperature changes from -40 to +50 ° C
• Wide range of thicknesses and sizes
Use:
- Building
- Transport
- Furniture
- Other
