There are 4 types of OSB according to their physical properties. Their moisture-resistant ability is depending on the glue used.
Applications
OSB/1 : general purpose OSB (interior use in dry conditions)
Glue: UF glue (Urea Formaldehyde)
Applications:
For non-structural usages, packing, furniture, decorating.
OSB/2 : load-bearing OSB (used in dry conditions)
Glue: PMDI(Isocyanate) for the core, MUF (Melamine-Urea-Formaldehyde) or PF(Phenol Formaldehyde) glue for the outer plies.
Applications:
Furniture, decorating, flooring, roofing, wall, signboards, packing, pallets.
OSB/3 : load-bearing OSB (used in humid conditions)
Glue: PF glue (Phenol Formaldehyde).
Applications:
Flooring, roofing, wall sheathing, signboards, packaging.
OSB/4 : heavy-duty load-bearing OSB (used in humid conditions)
Glue: PF glue (Phenol Formaldehyde).
Applications (Structure panel):
Structural components, wall sheathing, flooring & Subfloors, roofing, I-beams.
The density of OSB:
The density of common OSB is 650kg/CBM (+/-5%) . But the density varies with the wood species and compress ratio during production .
OSB is cheaper than plywood . The wood strands for OSB come from cheaper small logs. The wood veneers for plywood come from large logs .
OSB is a good substitute for plywood in some applications, such as furniture, roof, wall, sub floor, DIY and so on . The growth in global OSB consumption has been rapid in recent years .
China not only produces/exports OSB, but also imports OSB .
