Plywood with phenol formaldehyde adhesive. Water resistant, there is both sanded and unsanded plywood. Unsanded FSF plywood (NS) has a rather rough rough surface. It is usually used as a base for further finishing. The main advantage of such plywood is its low price, but at the same time the surface is strong, continuous and free of voids. Increased moisture resistance High strength and wear resistance Hard surface Ability to withstand heavy loads Resistance to temperature fluctuations: from -40 to +50 °С Versatility of application Aesthetic appearance Easy and convenient processing Resistance to external influences The field of application of plywood is extremely large. Depending on the thickness, softwood plywood sheets have different mechanical resistance. And this quality is decisive when choosing the scope of application of the material. Plywood of small thickness is used for the production of packaging structures, elements of decoration, handicrafts, invisible elements of furniture. The thicker the sheet, and accordingly stronger, the wider the scope of its application in areas where the material must withstand increased mechanical loads. Unfinished plywood with thickness more than 9 mm is successfully used in construction as a formwork and substrate for flooring, for padding the ceiling and roofing works, facing material with subsequent surface treatment, for the manufacture of furniture walls, packaging, containers, construction of various barrier systems and temporary structures. In addition, plywood is used in many industrial sectors, for example, in the production of airplanes, ships, cars. Plywood has always remained popular and irreplaceable in the work of craftsmen and designers. Products that can be obtained with its help, amaze the imagination. Inimitable forms, perfect execution, the most daring ideas make such a simple material as plywood something unusual and supernatural.
