What is Marine Plywood?
Marine plywood is a premium-grade waterproof plywood specially manufactured for areas exposed to high moisture and water.
It is made using:
- High-quality hardwood veneers
- Phenol Formaldehyde (PF) resin
- High-pressure hot pressing
- Gap-free core construction
- Boiling Water Proof (BWP) adhesive
A genuine marine plywood should comply with IS 710 standards.
What is BWP Plywood?
BWP stands for Boiling Water Proof plywood.
It refers to plywood bonded with Phenol Formaldehyde (PF) resin, which can withstand prolonged exposure to boiling water and high humidity.
Most reputed brands market their IS 710 Marine Plywood as BWP Plywood because it highlights its waterproof performance.
Are Marine Plywood and BWP Plywood the Same?
Short Answer:
Yes—when both are certified under IS 710.
In India, Marine Plywood is generally the commercial name, while BWP (Boiling Water Proof) describes the performance characteristic of the adhesive and construction.
However, some manufacturers use the term “BWP” for products that may not fully meet IS 710 requirements. That’s why you should always verify the certification.
Understanding IS 710 Marine Plywood
IS 710 is the Indian Standard for marine-grade plywood.
To qualify, the plywood must pass tests for:
- Bonding strength
- Boiling water resistance
- Glue shear strength
- Moisture resistance
- Core quality
- Durability
- Dimensional stability
Always look for the ISI mark with IS 710 before purchasing.
