As an environmentally friendly new material, plastic-wood composite materials are now receiving more and more attention, but there are also many places where the name “wood-plastic composite materials†appears.
The names "plastic wood" and "wood plastic" are actually the same concept. Because in the relevant materials, whether it is called "wood plastic composite material" or "plastic wood composite material", the English abbreviation is WPC.
WPC is an abbreviation for wood-plastic composites, which is defined in the ASTM standards: "acompositemadePurably from wood-orcellulose-based materials and plastic(s)". If literally translated, it is "a composite material made mainly of wood or cellulose-based materials and plastics (also a variety of plastics)." At present, China's production or R & D is basically belong to class materials.
The two different names “plastic wood†and “wood plastic†have caused certain troubles for the producers, users, design and management personnel, etc., especially when the new products are first contacted.
This kind of product, different titles have a unified necessity. However, it may be difficult to harmonize at present, the country or industry has not yet formulated a unified standard, there is no authoritative department to carry out this work, according to the current rapid development situation should speed up the formulation of national standards related to WPC, with the unified national standard name The problem is naturally solved. It is more appropriate to take "plastic wood" after unity.
1, because the main use of this material is to replace wood, it is different from pine, poplar, beech wood and other natural wood is that it is a synthesis of plastic and wood fiber "wood";
2. At present, the wood fiber content of plastic-wood composite products produced in China is mostly more than 50%, mainly wood, so it is more appropriate for “woodâ€;
3. In the definition of American Standard, the meaning of wood fiber-based raw materials is expressed. “Wood†is the main body; 4. Alias ​​is also used at home and abroad for such materials, such as “plastic wood†and “green woodâ€. The plastic-wood composite material produced by Japan’s Ain Corporation is called “Einmuâ€, and the total distribution of “Einmu†is also established in China, which is compared with “woodâ€. Therefore, it is called “plasticâ€. "Wood composite materials" (referred to as "plastic wood") is more reasonable.
There is a foreign article on the US WPC market, which mentions that the name of the composite material filled with fiber and natural fibers in the United States is also a bit confusing, some of them called Plasticlumber, some called WPC, through the relevant website for inspection, found in the United States For this type of material, in addition to WPC, there is a term that has a high frequency, which is "RPL" it is an abbreviation of "recycleplasticlumber", plasticlumber plastic is the attribute of lumber, so it should be translated into "plastic wood", It is defined in the U.S. standard as "an artificial product consisting of more than 50% resin, which may or may not be filled, or may consist of a single or mixed resin." The resin used in "RPL" is recyclable. The recycling resin, so it can be considered "WPC" and "RPL" difference is that WPC is filled with wood fiber, and RPL also includes plastic without filler. Another difference is that the plastics used in WPC can be new plastics or recyclable recycled materials, while the plastics in RPL are only recycled plastics that can be recycled. Japan has the name "synthetic wood".

Double Grille Linear Light is the most outstanding luminaire design in the lighting industry. Grille is very effective in solving the glare problem (UGR<13, UGR<16 & UGR<19). It can easily be used on this Grille linear light. It has been resolved, and LiteHome often uses high color rendering index SMD on this product, (CRI>85 Ra, CRI>90Ra, CRI>95Ra,CRI>97Ra) to better restore the original color of the irradiated object.
This product is suitable for supermarket lighting with high light requirements.
