Plastic wood ( PL ) is a plastic form of wood (wood) made of virgin or recycled plastic (in this case it can be called RPL ). Made of 100% plastic, compared to wood-plastic composite wood.
Widely used in outdoor decking, also used for printing and trim and garden furniture such as park benches.
Resistant to cracked and broken when properly mounted, wood plastic can be formed with or without detail of wood fiber simulation. Even with the design of wood grain, the PL is still easily distinguishable visually from natural wood: the grains have the same uniform color as other materials.
Manufacturers claim plastic wood is more environmentally friendly and requires less maintenance than wood/plastic composite or rotten wood. Unlike plastic composite woods, wood plastic is 100% recyclable after its original intended use.

Produksi
Wood plastic consists of virgin or waste plastic including HDPE, PVC, PP, ABS, PS and PLA. The powder or pellet is mixed with consistency as the dough is approximately 400 Â ° F (204 Â ° C) and then extruded or molded to the desired shape. Additives such as dyes, coupling agents, stabilizers, blowing agents, reinforcing agents, foams, and lubricants help to adjust the final product to the target application. This material is formed into a solid and hollow profile or to parts and injection molding products.
Resins, regrinds, and most additives are combined and processed in a pelletizing extruder. New material pellets are formed in mold and cooled. Pre-distribution testing can help determine the optimal combination of chemical agents, design, agitation, and other flow relief strategies for the particular materials used. Modern testing facilities are available to evaluate the material and determine the optimal combination of equipment components to ensure the highest level of accuracy and reliability. The computerized performance test reports the performance of document equipment.

Properties
Plastic wood can be formed to meet almost any desired spatial condition, a major advantage over wood. It can also be bent and fixed to form a strong curve curve. Plastic wood works like wood - can be formed using conventional woodworking tools. At the same time, waterproof and resistant to all types of decay and mold, although not rigidly wood and can be slightly damaging in very hot weather. Wood plastic is not sensitive to staining of various agents. The main selling point of this material is not to be painted. It is produced in various colors, and is widely available in gray and earth colors.
Engineering properties
While the compressive properties of plastic wood are equal to or greater than wood, the modulus of elasticity is very low. In addition, plastic wood is more vulnerable than wood.
Use in a retaining structure requires different considerations of wood.
Plastic wood can present problems with flame retention: these woods perform worse than various wood and composite materials in a test.
Plastic wood is also easily damaged at high temperatures, planning for a fire incident needs to take this into account.
Standard
ASTM has developed seven standard test methods to measure the PL properties:
- D 6108, Standard Test Methods for Plastic and Plastic Compression Properties;
- D 6109, Standard Test Methods for Bending Properties of Plastic Wood Not Reinforced and Reinforced;
- D 6111, Standard Test Methods for Specific Bulk Density and Specific Weights of Lumber Plastic and Shapes by Displacement;
- D 6112, Standard Test Methods for Compressive and Flexible Indentation and Plastic and Plastic Shape Cracking;
- D 6117, Standard Test Method for Mechanical Fasteners in Lumber and Shapes Plastics;
- D 6341, Standard Test Method for Determination of Linear Coefficients of Plastic Thermal Extension of Lumber and Plastic Wood Shapes Between -30 and 140Ã, Â ° F (-34.4 and 60Ã, Â ° C);
- D 6435, Standard Test Method for Shear Properties of Plastic Lumber and Plastic Lumber Shapes.
