In many grades of plywood used across the globe, BWR plywood is one of the most popular choices. It is stronger and more moisture resistant than MR grade and less expensive than BWP grade. Catering to a large market demand for a reliable plywood that shows excellent material properties, the BWR grade plywood manufacturers in India provide this for various residential and commercial uses. Though it follows the standard procedure of bonding the veneers of hardwood with water-resistant adhesives, the temperature and pressure at which this is bonded create the essential difference and set it apart from the rest. Let’s understand what BWR grade plywood is, its uses and advantages.
What is BWR Plywood?
The BWR plywood is boiling water resistant plywood. And as the name suggests, it is made to withstand water exposure without degradation. It is made by bonding veneer from hardwood trees like eucalyptus and birch. The bonding material used in BWR plywood is phenol-formaldehyde. The temperature and pressure at which bonding is done are 140~160 °C and 11.5~14.5 atm, respectively. The pressing time lies between 6~8 minutes/mm of thickness. The adhesive goes through complete polymerization at a temperature where thermal degradation can’t occur.
Advantages of BWR Plywood
One of the key advantages of BWR plywood is its ability to withstand moisture and water exposure without degrading. The BWR grade plywood manufacturers in India, like Aadya Ply conduct rigorous tests, which include immersing the plywood in boiling water. It retains its form despite long exposure, and tests show it swells only up to 5 % when exposed for 24 hours. The adhesives have a strong bond that does not let water molecules into the plywood layers. Due to this, BWR plywood has excellent strength and chemical and thermal properties. Here are the advantages of BWR grade plywood:
➔ Water and Moisture Resistant: These are the prominent advantages of BWR grade plywood. It can withstand a significant amount of water exposure, frequent contact and high humidity.
➔ Termite & Borer Proof: Special chemical treatment is done to enhance the termite and borer resistance of the BWR plywood. It prevents pests and mold from damaging the furniture, panels, or any woodwork crafted from this plywood.
➔ Finishing Compatibility: This plywood can be finished with paint, polishing, veneer and lamination, showing its high compatibility with various finishes.
➔ High Durability: The high strength, pest resistance, and moisture resistance properties make it highly durable and cost-effective in the long term.
Uses of BWR Plywood
BWR grade is an exterior grade of plywood, meaning it can be used in both interior and exterior applications.
● Kitchen cabinet, undersink installations, pantry systems
● Bathroom vanities and boxes
● Outdoor chair, sofa and table
● Partition walls and ceilings
● Doors and window frames
● Laboratory, food service and hospitality areas where water contact is frequent.
