What is Medium Density Fibreboard(MDF)?
As one of the biggest four leading panels, MDF is the first grade, mainly made of botanic fibers from fast-grown woods, small logs and processed wood leftover, through the processes of fiber grading, drying, forming and pressing.
Product Advantage
◇ Cheaper and environment-favorable than natural logs.
◇ Big-dimensioned sheet, customer-required size.
◇ Stable quality from overall-controlled production, some properties better than natural wood,
such as water-proof, fire-extinguishing, anti-pressing, less variability, etc.
◇ Product surface satisfies direct use's requirement, saved much processing cost.
◇ Solid interior property, constant quality in the longitudinal and transverse direction.
Convenient for any processing:
