XIBOND™ 240

XIBOND™ 240 by aurorium is a styrene and maleic anhydride random copolymer. Acts as a chain extender, viscosity modifier, surface modifier, compatibilizer, adhesion promoter and coupling agent. It is designed to improve the blend morphology of specific polymer blends. XIBOND™ 240 can be processed using extrusion in all types of regular polymer processing equipment. 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. As a coupling agent, it provides low viscosity, improved creep and tensile properties. 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. 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 %.
