Introduction

Extreme Density High Moisture Resistance (EDHMR) is an engineered wood product that is similar to Medium-Density Fiberboard (MDF) but has an extreme density and strength. It is manufactured by breaking down wood fibers or particles, combining them with wax and a resin binder, and then subjecting the mixture to high temperature and pressure to create a dense and strong panel.
