Nov 14, 2005 . Effective interfacial adhesion between wood fibers and plastics is crucial for both the processing and ultimate performance of woodplastic composites. Coupling agents are added to woodplastic composites to promote adhesion between the hydrophilic wood surface and hydrophobic polymer matrix, but..
Highly magnified views show how. DuPont Fusabond M603 coupling agent (right side panels, above) helps with wood fiber dispersion and internal bonding with PE-based polymer. Using Fusabond M603 as a coupling agent in wood- polymer composites (WPCs). Guidance on cost-effective blend rates
CP750 750 watts ultrasonic horn was used to agitate the mixture when required. Treated fibers were then mixed with PP in a Leistritz co-rotating twin-screw extruder to obtain WPCs with 50% wood content. PP grafted maleic anhydride was used as the coupling agent. Later, a Battenfeld. BA 1000-CDC injection molding..
