XIBOND™ 220

XIBOND™ 220 by aurorium is a styrene and maleic anhydride random copolymer. Acts as a coupling agent, compatibilizer, adhesion promoter, chain extender, surface- and viscosity-modifier. It is designed to improve the blend morphology of specific polymer blends. Compatibilizer optimizes the interfacial tension and morphology against high stresses. As a coupling agent it provides low viscosity, improved creep and tensile properties. The viscosity modification lowers the molding temperature and provides better surface appearance. Chain extender connects polymer chains together to raise the molecular weight, melt strength, processability, flow properties and thickness. Surface modifier changes the polarity of a product leading to a different surface tension of the polymer matrix and modifies the adhesion properties of the polymer. XIBOND™ 220 can be processed using extrusion in all types of regular polymer processing equipment. It is compatible with acrylonitrile butadiene styrene (ABS) resins. 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 %.
