ALTIMATE

MR and BWR grade, IS:303 HIGH DENSITY & LONG LIFE PLYWOOD

TRIBECA ALTIMATE is available in Moisture Resistant (MR) and Boiling Water Resistant (BWR) grades. Both the grades are used for the interior and exterior woodworking application. This ISI marked M.R. grade plywood is bonded with Melamine Urea Formaldehyde Synthetic Resin, While the BWR grade plywood is bonded with Fortified Phenol Formaldehyde Synthotic Resin as per standards of IS: 848 1974 under controlled temperature and pressure with adequate timings to obtain unmatched bonding. It is used in any application that needs high quality wooden sheet material and it is an economical option for better wood working. It also has resistance to cracking breaking shrinkage, twisting and warping
