The wood chips are glued together with adhesive and processed under high temperature and high pressure. Plywood has the characteristics of high strength, good flatness, not easy to deform, not easy to crack, etc., so it is widely used in construction, furniture manufacturing, transportation, packaging and other fields. Flame-retardant plywood is a specially treated plywood with fire-proof function.
