Effects of silane and MAPE coupling agents on the properties and ...6 Mar 2008 ... To improve the mechanical properties of the composites, silane A-137 (Octyltriethoxy silane), silane A-1100 (-aminopropyltriethoxy silane), or MAPE (maleic anhydride-grafted-polyethylene) were introduced. It was found that the additions of silane A-137, silane A-1100, and MAPE could improve tensile and impact properties of the composites, regardless of the sawdust contents.

Coupling Agents | DuPont USABy improving the properties and processing efficiency of pre- and post-consumer recycled plastics, for example, Fusabond coupling agent can lower costs for manufacturers of industrial packaging and plastic lumber. Benefits also reach blow molders, injection molders, compounders and others who are feeding into or using higher-value polyethylene- (PE-) based recycle streams. In wood composites, Fusabond M603 coupling agent strengthens the composite and reduces ...【Get Price】

Effect of silane coupling agents on the properties of pine fibers ...27 Dec 2006 ... SH, long aliphatic chain, and methacrylic group were chosen as functionalities of the silane derivatives for evaluating the compatibility with the matrix. Mechanical analysis, contact angle and XPS spectra, SEM microscopy, and water uptake measurements were used as characterization techniques for evaluating the nature of composites. XPS as well as contact angle measurements demonstrated that pine fibers and silane derivatives were effectively coupled.【Get Price】

Extruded composite compositions of pvc and wood particles containing chitosan or chitin as a coupling agent are described. The composite ... [0009] In spite of these benefits, -amino propyltriethoxy silane has not been extensively used as a coupling agent for pvc/wood-fiber composites, mainly due to its high cost but also due to the difficulty in evenly coating the surface of wood fibers, owing to its sensitivity to hydrolyze and self- condense. Consequently ...【Get Price】

Different coupling agents in wood-polypropylene ... - SAGE JournalsAbstract. coupling agents can have a major effect on the various properties of wood-plastic composites. In this study, the effects of maleated polypropylene and -methacryloxypropyl trimethoxy silane as coupling agents on the mechanical and moisture resistance properties of wood-polypropylene composites containing recycled mineral wool are investigated. The spraying method was used to apply -methacryloxypropyl trimethoxy silane on the wood fibers and recycled mineral wool ...【Get Price】

Composites of polyvinyl chloridewood fibers. III: Effect of silane as ...Abstract. The performance of silanes as coupling agents in hardwood aspen fibers (chemithermomechanical pulp and sawdust)polyvinyl chloride composites, have been investigated. Aside from the chemical structure of silanes, the dispersion aids, e.g. solvent, initiator (different organic peroxides) and maleic anhydride (which provides various chemical reactions as well as physical/chemical inter-actions at the interface), play important roles on the mechanical properties of the ...【Get Price】
