1. Different production processes
Plywood is a three-layer or multi-layer board like material made by rotary cutting wooden sections into veneers or by planing wooden blocks into thin pieces, and then bonding them together with adhesive; MDF is a board made by separating wood or other plants into fibers, utilizing the interweaving between fibers and their inherent bonding substances, or applying adhesives, under heating or pressure conditions.
2. Different product categories
Plywood is divided into four categories based on its bonding strength: one is weather resistant and boiling water resistant plywood. This type of plywood has durability, resistance to boiling or steam treatment, and can be used outdoors; Class II plywood is water-resistant plywood that can be immersed in cold water and short-term hot water immersion; Three types of plywood are moisture resistant plywood that can be immersed in cold water for a short period of time and is suitable for indoor use at room temperature. Used for furniture and general building purposes; Four types of plywood are non moisture resistant plywood, which is commonly used indoors. General purpose plywood materials include beech, oak, water chestnut, birch, elm, poplar, etc.
Density boards are divided into three categories based on their density: low-density boards, medium density boards, and high-density boards.
