According to the core material, there are mainly all poplar plywood, eucalyptus poplar mixed core, all eucalyptus, all birch.
Pine, hard wood, relatively dense, oily, so waterproof, strong elasticity and air permeability, good thermal conductivity, pine has a long growth cycle, fine annual rings, flexible wood texture, low oil content, and its own yin and yang colors. evenly distributed.
However, pine wood is soft, easy to crack and deform, and high moisture content can easily lead to cracking. It is easy to change color, especially in sunlight, so it should be strictly prevented. Pine itself is oily, so poplar is generally used for the outermost two layers, otherwise it cannot be veneered, and the price is high. Pine of the same specification is about 20--30 percent more expensive than poplar. Mainly used for high-end furniture. Rarely seen in the market.
Poplar wood is easy to obtain, but poplar fiber structure is loose, the material is relatively poor, and it is easy to deform, but it is widely used. There are many types of poplar plywood and a wide range of applications. It is the most plywood in the market, building formwork and low-end furniture on the market The boards are all poplar plywood, mainly including boxwood, poplar blockboard, all poplar plywood, LVL LVB plywood, all poplar bleached plywood, all poplar plywood for furniture, all poplar CARB plywood for panel furniture. Most builders choose poplar building formwork, which is low in cost. Compared with the price and the frequency of use, poplar is still suitable.
Eucalyptus wood is harder than poplar wood, the resulting plywood is less deformable, more expensive, and the wood grain is tight and irregular. The sapwood layer is wider and white to pale pink; the heartwood is light brownish red. Eucalyptus is a fast-growing wood that is not tough and lightweight. Eucalyptus is widely grown in the southern and central United States and has a variety of uses in the production of cabinets and furniture, especially in the production of antique furniture. Eucalyptus plywood is the most widely used mid-to-high-end furniture board and mid-to-high-end decorative board in China.
The wood of birch is light brown to reddish brown with a shiny surface and smooth mechanism. The wooden body is pure and thin, slightly heavy and hard, with fine structure, high mechanical strength, elasticity, high hygroscopicity, and is easy to crack and warp when dry. Birch wood is commonly used in specialty plywood, flooring, furniture, pulp, interior trim materials, vehicle and boat equipment, plywood, and more. The furniture made is smooth and wear-resistant, with clear patterns. It is mainly used in the market for high-end furniture panels and for export.
