Boiling Water Resistant (BWR Grade-Phenol Bonded) Plywood

Sonear BWR Plywood is bonded with high Quality Phenol Formaldehyde Resin. It undergoes a chemical impregnation treatment under high temperature and pressure. The result is a high quality ply that can resist boiling water, cold water, climate variations, and powder and termite attacks. It does not delaminate even when immersed in boiling water for more than Eight hours. It is ideal for use in hot, humid and moist locations.

Areas of Application
Ideal for exterior and interior applications, like Furniture and Fixtures, Woodwork in Kitchens and Bathrooms, Partitions, Door Panels & Inserts.
