This research is a study of mixing process and recycled plastic ruprawang type polymer powder and polyurethane rubber wood raphi. Rubber wood used as a cost-saving in production because it does not need to import timber from overseas and the rest of the wooden materials used in the production process, from the factory to produce a renewable material, wood. Using the ratio of recycled plastic wood powder 50.3%, 44.5%, 3.9%, alongside a pair of chemical antioxidant 0.2% UV, and lubricant 1%, mixed with a single screw extrusion machines and extrusion forming process with heat and mechanical properties testing according to ASTM standards which will make up the treasure to the bending strength MPa compression strength at 29.95 45.29 MPa and tensile strength MPa 20.05, which found that the mechanical properties of bending strength, tensile strength and lower. Best compression strength is higher when compared to wood plastic composite extrusion machine undergoes a double helix.
