Commercial Plywood Vs Marine Grade Plywood - lceted

In this article, we explained the differences between commercial plywood and marine plywood, not only in quality and properties but also in cost. This article compares these two types of plywood.

 

 

Factors	Commercial Plywood	Marine Grade Plywood
Water-resistance	Commercial plywood is of MR grade (Moisture resistant) grade. Note that 'moisture resistant is not the same as being 'waterproof'. It only means that the plywood can withstand some amount of moisture, dampness and humidity.	Marine plywood is a completely waterproof Plywood, that has been specifically manufactured for marine applications.
Adhesive used	The adhesive used for bonding the plies together is Urea-formaldehyde.	Unextended phenolic resin is used for bonding the plies together. Unextended means are undiluted. Phenolic resin is a synthetic plastic resin made from phenol-formaldehyde and it makes Marine plywood completely waterproof.
Uses/application	Commercial plywood is most commonly used in the making of home and office furniture, and interior decoration work such as panelling, partitions and the like.	Marine plywood is used for building boats and ships, and any other applications in which the plywood is sure to get a large amount of exposure to water.
Grade	It is an Interior grade plywood that is meant for indoor use.	Marine plywood is of Exterior grade and meant for extreme exterior uses. Its also better than the Exterior grade BWR (Boiling Water resistant) plywood that is used for making kitchen furniture.
Cost	Cheaper compared to Marine plywood.	It is a lot costlier than Commercial ply.
Strength	Its strength is weaker compared to the strength of Marine ply.	It is much stronger than Commercial grade plywood because of the superior wood and glues used in its manufacture.
Codebook used	Indian standard for Commercial ply is detailed in document IS:303	Indian standard for Marine plywood is specified in the document: IS:710
