Plywood has advantages such as small deformation, large width, convenient construction, no warping, and good tensile resistance in transverse lines. This product is mainly used in various boards for furniture manufacturing, interior decoration, and residential buildings. Next are industrial sectors such as shipbuilding, vehicle manufacturing, various military and light industrial products, and packaging.
The natural wood itself has many defects,including wormhole, dead knots, distortion, cracking, decay, size limitations and discoloration. Plywood is produced to overcome the various defects of natural wood.
The common furniture plywood, has good characteristics and advantages and suitable for making furniture. But the problem is that it can’t be used outdoor. Plywood which suitable for outdoor is another type of plywood called exterior plywood or WBP plywood.
Types of Plywood
How many types of plywood are there? According to different classification standards, there are different plywood types as follows:
commercial plywood,
film faced plywood
hardwood plywood
furniture plywood
fancy plywood
packing plywood
melamine plywood
One way is to classify the types of plywood according to its own properties.For example, according to the waterproof performance of plywood itself, plywood can be divided into moisture-proof plywood, ordinary waterproof plywood and waterproof weatherproof plywood. Common interior plywood is moisture-proof plywood, Like furniture plywood. For ordinary outdoor use, choose ordinary waterproof plywood.However, if the use environment may make the plywood exposed to the sun and rain, in this case, it is best to use waterproof weatherproof plywood which is most durable in a harsh environment.
Moisture and water is the natural enemy of all wood products and natural wood/lumber is no exception. All plywood is moisture-proof plywood. Waterproof plywood and weatherproof plywood should be considered only when the plywood is likely to be exposed to water or in a humid environment for a long time.
Some interior furniture plywood with expensive natural veneer are more expensive. Of course, waterproof and weather-resistant plywood is not necessarily used for outdoor use. It may also be used in kitchens, bathrooms and other places where moisture is very heavy.
Plywood Emission Grade
According to the formaldehyde emission grade of plywood, plywood can be divided into E0 grade, E1 grade,E2 grade and CARB2 grade. E0 grade and CARB2 grade plywood has the lowest formaldehyde emission level and is also the most environmentally friendly. E0 grade and CARB2 plywood is mainly used for interior decoration and furniture manufacturing.
Plywood Grade
According to the appearance grade of plywood, plywood can be divided into various types, such as A grade, B grade, C grade, D grade and so on. B/BB grade Plywood means that its face is B grade and its back is BB grade. But actually in the production of B/BB plywood, we will use better B grade for face and lower B grade for back
A grade, B/B, BB/BB, BB/CC, B/C, C/C, C+/C, C/D, D/E, BB/CP are all common plywood grade names. Usually, A and B represent perfect grade . B, BB represents the beautiful grade. CC, CP represents the ordinary grade. D, E represents the low-grade.
Plywood Size
About the size plywood can be divided into standard size and customized plywood. The standard size is 1220X2440mm.In general, buying a standard size is the wisest choice. Because the production of standard size boards in large volume. It can maximize the use of raw materials, machinery and equipment. Thus the production costs is low .However, according to customers’ requirements we can make the special size plywood for them .
Plywood face veneers
According to the face veneers of plywood , Plywood can be divided into birch plywood, Eucalyptus plywood. beech plywood , Okoume plywood, Poplar plywood, pine plywood, Bingtangor plywood, Red oak plywood, etc. Though the species of core may be different . Such as Eucalyptus ,poplar , hardwood combi , etc
Plywood can be divided into Structural plywood and Non Stuctural plywood. Structural plywood have superior mechanical properties like bonding quality, bending strength and Modulus of elasticity in bending . Structural plywood can be used for building house. Non Stuctural plywood are used for furniture and decoration .
Plywood is not only required to be waterproof, it is also required to be wear resistant. At this time,with the development of plywood market, people put a layer of waterproof, wear-resistant,dirt-resistant and chemical-resistant film paper on the surface of plywood which is called melamine faced plywood and film faced plywood. Later they require plywood to be fire-resistant.Because wood is easy to catch fire, it requiresthe wood to be fire-resistant.Therefore they put a layer of fire-resistant paper on plywood, which called HPL fire-resistant plywood. These film/laminate on the surface have greatly improved the performance of plywood. They are waterproof, corrosion-resistant, wear-resistant,fire-resistant and durable. They are widely used in the manufacture of furniture and decoration.
Plywood such as the commercial plywood, furniture plywood, packing plywood.
