Mérida Plywood is available in MR & BWR types. Made from the high density selected hardwood species.100% Composed Core.
Each and every layer is treated with Boric & Borax solution and every layer is glue Line poisoned to ensure complete protection from insects.
The inner core and outer surface are made from superior quality wood and is bonded by Urea Formaldehyde resin in MR grade and Phenol Formaldehyde resin in BWR grade.
The plywood has strong screw holding capacity and is extra resistant to moisture, water, borer and external weather conditions.

The acronym BWP stands for 'Boiling Water Proof', while BWR grade means 'Boiling Water Resistant' plywood. The general naming convention used in the industry is that BWR grading is used for marking plywood, while its counterpart BWP grade is used in the case of Blockboards.
BWP Marine Grade plywood from Mérida that has been developed suiting all parameters of IS:710. It is Borer-Termite proof. Available at a very competitive price. Unique GLP Formula To Make Plywood Borer and Termite Proof, 12 Year Warranty Against Borer And Termite, More Number Of Plies For More Strength, Pre-Pressing is a Process Which is A Speciality Of Quadra Press Technology - For No Delamination and More Life
