MR Grade Plywood is moisture and cold water resistant. It is mainly made from selected imported GURJAN hardwood duly fortified with melamine, a chemical which enhances the water resisting qualities. Melamine fortified MR Grade Plywood is a superior product for a vast range of items including house hold furniture, partitions and Value Added high quality commercial wood-working. BWR grade plywood is made from selected imported GURJAN hardwood and is Phenol Formaldehyde (PH) bonded, which makes it boiling water resistant.
This grade is used for the interior and exterior woodworking application.
MR grade plywood is manufactured with phenol-formaldehyde resin.
| Applications | : | This product is suitable for internal and external application and all kind of furniture use. |
