Influence of the use of Renewable Compatibility Agent Wood Plastic Composite (WPC)

The growing interest in using recycled and natural materials the application of new composites recent years implies ecological, economic versatility benefits. Wood plastic composite (WPC) are considered very attractive materials, as they allow use polymers or virgin origin, associated with forestry by-products. present work aims to investigate influence on mechanical, thermal morphological resistance WPC, oleic acid glycerol renewable coupling agents. Composites were also prepared a commercial compatibility agent its formulation - maleic anhydride grafted polypropylene (MAPP) under same conditions. single-screw extruder, fixed contents 5% sawdust 95% polymer, this total, 2% agents: MAPP, glycerol, according desired composition. To be evaluated changes mechanical properties, tensile impact strength tests performed specimens obtained through injection molding process. fracture surfaces tested examined images generated by scanning electron microscopy. stability was investigated thermogravimetric analysis. improved properties composite. An increase is observed when added As for strength, addition around 58% higher compared without agent. Glycerol renewable, low-cost alternative potential substitute especially main requirement obtain better properties.
