HMR MDF :wood fiber +glue +ammonium chloride curing agent +Moisture-proof agent+acid green stain, just has E1 E2 two kinds formaldehyde emission standard , glues ,no E0 glue
Our HMR MDF knowledge : plain HMR MDF : Calendering is to hot press or cold press MDF with pressure rollers, in order to improve the surface finish of MDF. melamine HMR MDF: Sanding is to make the surface of the board smooth and increase the strength of the surface at the same time, the thickness is uniform, suitable for various veneering processes. and both dopting flat pressing line equipment (the board has no burrs, the flatness of the board surface is good, and the density of the board is uniform) The coloring agent only distinguishes HMR MDF from other MDF series, for example, FR MDF is red. HMR MDF is green because paraffin wax is added to the board. Paraffin wax not only makes the surface of the board smoother, but also has a moisture-proof effect. A moisture-proof agent is added to the board in a certain proportion to enhance the moisture-proof effect. Moreover, melamine glue also has a certain moisture-proof effect. Compared with ordinary MDF, the moisture-proof performance is only increased, but if the board is soaked in water for several days, the board will also be damaged to a certain extent. All wooden boards are afraid of being soaked in water for a long time. Generally, HMR MDF is usually used in places such as kitchen and bathroom, and the melamine impregnated papers on the surface have a certain blocking effect on water vapor, etc.
HMR MDF has two environmental protection grades, E1 and E1. The environmental protection grade of E1 (formaldehyde emission content)>E2, moisture-proof performance: the moisture-proof performance of HMR MDF of E2 is greater than that of E1.
