AK/APPLE HD HMR

AK/Apple HD HMR is highly moisture resistant for use in areas of high humidity or area where occasional wetting may occur. It is designed for interior application ranging from kitchen cup boards, bathroom vanities, laundry cupboards, shelving or any situation where a moisture resistance is required.
The unique feature of HDHMR is that it has homogeneous structure and uniform properties which ensures equal strength in all directions. It can be painted or stained to look just like wood and it will not expand and contract due to heat and humidity.
It has high screw retention strength on face and edges and it can be moulded, profiled, routed and grooved like natural wood. It can also be laminated, veneered, lacquered, painted or coated with PVC.
