What is commercial plywood?

Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which includes medium-density fibreboard (MDF) .Commercial plywood generally refers to the grade of plywood, usually referred to as MR grade plywood (IS 303), which is usually made up of a combination of softwood and hardwood or just cork.

Although commercial plywood is made from different plywood, the basic properties of commercial plywood remain the same. The internal materials are the same. The only difference is its manufacturing process or processing method (which varies according to each manufacturing unit), followed by the adhesive used to bond the plywood. Urea-formaldehyde is commonly used as a binder to bond plywood.

The difference between Marine Plywood and Commercial Plywood

1. Commercial plywood is of the MR grade (moisture proof) grade. Please note that "moisture proof" is not the same as "waterproof". It only means that the plywood can withstand a certain amount of moisture and humidity. Marine plywood is a completely waterproof plywood that is primarily manufactured for marine use.

2. The binder in the commercial plywood that bonds the plywood together is urea formaldehyde. In marine plywood, unexpanded phenolic resin is used to bond plywood together. Unexpanded means not diluted. Phenolic resin is a synthetic plastic resin made of phenolic resin that makes marine plywood completely waterproof.

3. In terms of use. Commercial plywood is the most commonly used to make home and office furniture, as well as interior work such as paneling, partitioning and more. This is an indoor grade plywood for indoor use. Marine plywood is used to build ships and ships, as well as any other application where plywood is sure to come in contact with large amounts of water. Its strength is weaker than that of the sea layer. Marine plywood is an external grade for extreme external use. It is also superior to external grade BWR (boiling water resistant) plywood for making kitchen furniture.

4. In terms of price. Commercial plywood is cheaper than marine plywood. Marine plywood is much more expensive than commercial plywood. But marine plywood is much stronger than commercial grade plywood because it uses fine wood and plywood in its manufacture.
