Technical Datasheet | Supplied by Polyscope
XIBOND™ 250 by Polyscope is a styrene and maleic anhydride random copolymer. Acts as a viscosity modifier, surface modifier, compatibilizer, adhesion promoter, extender and coupling agent. Compatibilizer optimizes the interfacial tension and morphology against high stresses. 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. As a coupling agent it provides low viscosity, improved creep and tensile properties. It is designed to improve the blend morphology of specific polymer blends. XIBOND™ 250 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 %.
