Product Details

XIBOND™ 220 is a styrene and maleic anhydride random copolymer. It 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 %.

Typical Applications

XIBOND™ 220 acts as a coupling agent, compatibilizer, adhesion promoter, chain extender, surface- and viscosity- modifier. 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.
