01. Application

VRG Dongwha Medium Density Fibreboard (MDF) is an engineered wood panel product. It is specially manufactured for furniture and joinery industries. The homogenous nature of Dongwha fiberboard has consistency from surface to core. And its versatility allows intricate and precise machining and finishing techniques when producing high quality furniture, cabinetry components, craft work and flooring.

The overall strength and smooth surface of VRG Dongwha fiberboard make it suitable for painting to achieve high quality finishing and provide a uniform substrate for overlaying. Furthermore, it can be worked easily with all conventional woodworking and hand tools.

We also manufacture low emission product (E1, E0, CARB). Its formaldehyde content of standard grade MDF can vary according to the nature of the urea formaldehyde or other resin used as a binding agent. Low formaldehyde MDF, is recommended for all applications where the ventilation is likely to be restricted, where damp conditions or high ambient temperatures prevail or where the occupants of a building have special needs, in sheltered accommodation, schools and hospitals, for instance.

The binder or resin used for these types of product are developed to ensure they meet specific formaldehyde emission requirements but at the same time maintain the overall strength and the smoothness of the surface.
