What is Boiling Waterproof (BWP) Plywood?
Boiling Waterproof (BWP) plywood is a type of plywood that is specifically designed to withstand extreme moisture and water exposure. It is manufactured using high-quality hardwood veneers and phenolic resins, which provide superior bonding strength and water resistance. The term “boiling waterproof” indicates that the plywood can endure boiling water without delaminating or losing its structural integrity.
Key Features of BWP Plywood
- High Water Resistance: BWP plywood can withstand prolonged exposure to water and moisture.
- Durability: It is highly durable and can last for many years even in harsh environments.
- Strength: BWP plywood has excellent load-bearing capacity and structural strength.
- Termite Resistance: It is resistant to termites and other pests.
- Low Maintenance: Requires minimal maintenance compared to other types of plywood.

Manufacturing Process of BWP Plywood
The manufacturing process of BWP plywood involves several critical steps to ensure its high quality and water resistance.
1. Selection of Raw Materials
High-quality hardwood veneers are selected for the production of BWP plywood. These veneers are carefully inspected for any defects or imperfections.
2. Bonding with Phenolic Resins
The veneers are then bonded together using phenolic resins, which are known for their excellent adhesive properties and water resistance. The resin is applied evenly to ensure a strong bond between the layers.
3. Hot Pressing
The bonded veneers are subjected to high pressure and temperature in a hot press. This process ensures that the resin cures properly, resulting in a strong and durable plywood sheet.
4. Quality Control
Each sheet of BWP plywood undergoes rigorous quality control tests to ensure it meets the required standards. These tests include checking for water resistance, strength, and durability.

Maintenance and Care of BWP Plywood
1. Regular Cleaning
To maintain the appearance and durability of BWP plywood, it is important to clean it regularly. Use a mild detergent and water to remove dirt and grime.
2. Avoid Prolonged Exposure to Direct Sunlight
While BWP plywood is highly resistant to moisture, prolonged exposure to direct sunlight can cause it to fade or degrade over time. Use protective coatings or finishes to prevent this.
3. Inspect for Damage
Regularly inspect the plywood for any signs of damage, such as cracks or delamination. Address any issues promptly to prevent further deterioration.
4. Apply Protective Coatings
Applying protective coatings such as varnish or paint can enhance the durability and appearance of BWP plywood. These coatings also provide an additional layer of protection against moisture and UV rays.
