General
1. Definition of OSB
OSB (Oriented Strand Board) is a type of wood-based panel made up of shavings and adhesives.
2. Formation and development history
- Armin Elmendorf invented the OSB board in California in 1963.
- OSB boards were originally introduced to the market in the late 1970s.
- In 1980, North America produced 751 million square feet of OSB boards.
- Production of OBS boards increased 7.6 billion ft2 in 1990 to 25 billion ft2 in 2005.
- For the first time, total global production of OSB board surpassed that of plywood in 2000.
3. Components of OSB
- Typically, the board's composition is 95% wood and 5% glue.
- OSB is mostly made up of shavings (or big wood chips) that have been organized in a specific orientation.
- Typically, Phenol Formaldehyde (PF) glue or Melamine Urea Formaldehyde (MUF) glue is utilized in manufacture.
4. Manufacturing
The shavings are organized in a specific direction and pressed with a binder under high temperature and pressure.
5. The Advantages of OSB
- Ordinary OSB board is less expensive than plywood.
- Has a high hardness and mechanical strength, as well as good bonding.
- Has a high degree of screwing-holding and elasticity. Consistency in high humidity settings.
- Because plywood is light in weight, it is simple to construct.
6. Disadvantages of OSB
- Because the surface of OSB board is finished, it is challenging to apply paint on.
- Compared to plywood, when there is moisture inside the board, OSB boards dry longer.
7. Applications
- Floor coverings, wall partitions, display shelves, and support frames for other interior products are all common uses for OSB boards.
- Furthermore, boards are widely employed in the construction business. Because of its high rigidity and mechanical strength, it is commonly utilized as a support frame.
- OSB boards, in particular, are employed as containers due to their excellent resilience.
