XIBOND™ 285

XIBOND™ 285 by aurorium is a maleic anhydride polymer. Acts as a coupling agent, extender, compatibilizer, adhesion promoter and viscosity- & surface modifier. It is designed to improve the blend morphology of specific polymer blends. XIBOND™ 285 can be processed using extrusion in all types of regular polymer processing equipment. It is compatible with acrylonitrile butadiene styrene (ABS) resins. Chain extender connects polymer chains together to raise the molecular weight, melt strength, processability, flow properties and thickness. Compatibilizer optimizes the interfacial tension and morphology against high stresses. The viscosity modification lowers the molding temperature and provides a better surface appearance. Surface modifier changes the polarity of a product leading to a different surface tension of the polymer matrix and modifying the adhesion properties of the polymer. As a coupling agent, it provides low viscosity, improved creep and tensile properties. It is recommended to use twin screw extruders with a mild screw configuration and vacuum degassing facility for good dispersion in styrenic polymer. Recommended dosage level is 1-5 %.
