Wholesale Moisture proof MDF

    Medium density fiberboard is made of wood fiber and other fibers as raw materials, prepared by fiber, then applied with synthetic glue and other functional materials, and pressed into boards with different thicknesses 

and densities under heat and pressure. Among them, the moisture-proof MDF is made of modified melamine cyanamide adhesive or MDI type adhesive, and the use of waterproofing agent is improved at the same time. amount, to achieve moisture-proof performance.

According to the national standard [GB National Standard] GB-T-11718-2021 medium density fiberboard, the moisture-proof board can be classified into MDF-FN-MR in wet state and MDF-FN-HMR in high humidity state according to the use environment.
