High-density boards are classified into high-density boards, medium-density boards, and low-density boards according to their density. Due to its high softness and impact strength, the MDF has a uniform density and is easy to be reprocessed. It is a good material for making furniture in foreign countries, but the disadvantage is poor water resistance. Medium and high-density boards are made by crushing and grinding small-diameter wood under high temperature and high pressure. The density of the low density board is less than 400 kg/m3, and the density of the medium density board is 400 kg-800 kg/m3. Wenzhou Shenwei Hardware Co.,Ltd , https://www.cn-shwshw.com
