Purpose: Purpose of this paper is to utilize synthetic base mineral filler in wood plastic composites (WPCs) and to determine their physical, mechanical and thermal properties. Design/methodology/approach: Hybrid composites were produced by mixing wood flour (Turkish red pine (Pinus brutia Ten.), wax and maleic anhydride grafted polypropylene (MAPP) and polypropylene (PP) in a high intensity density mixer. The homogenous mixture was extruded using a single screw extruder with five heating zones. Extrudates were pelletized and composite samples were injection molded. Density of the samples was measured (ASTM D 792). Flexural strength (ASTM D 790), flexural modulus (ASTM D 790), tensile strength (ASTM D 638), tensile modulus, elongation at break and hardness (ASTM D22-40) were studied. Linear burning rate of the samples were also determined (ASTM D 635). Findings: According to test results synthetic based mineral filler and wood flour can use together for better composite properties and they provide adequate mechanical properties according to ASTM D 6662. Research limitations/implications: This article determined some of physical and mechanical properties of wood plastics hybrid composite which was manufactured with Turkish red pine flour and synthetic based mineral filler. As for the future researchers the some wood plastics composites can be manufactured by different wood flour species and in different amounts of synthetic based mineral filler. Practical implications: Synthetic based mineral filler were added to the mixture either before extrusion or injection molding. Effect of mineral filler and wood flour amount was also studied. Originality/value: Addition of wood flour and synthetic based mineral filler into polypropylene improved modulus values while reducing tensile strength, elongation and impact values.
