Abust^® and Mebust^® 

Ultra-low temperature impact modifiers for the engineering resins. For use in automotive, aerospace, marine, military, and power cable industries.

A decade of expertise in new polymer innovations has yielded uncompromising pelletized ultra low temperature (< -55^oC) impact modifiers for PBT, PC, and NYLON(s) by PolyChem Alloy^®, Inc. (PCA). This innovation has been possible because of PolyChem’s captive expertise in process development coupled with the ability to customize extrusion machinery. Trade named ABUST^® and MEBUST^®, these virgin impact modifiers with butadiene content in excess of 65% have no melting point and can easily be mixed with an array of high temperature (>250^oC) engineering resins. Test data attached reflects optimum use levels for formulators and compounders of low-temperature impact modified compounds for injection molded parts.

Effect of Impact Modifiers (5 to 10 wt. % loading) on Physical

Mebust^® 1507S298 Modifier also shows good efficiency in various polyester blends such as PC/PBT. The following table demonstrates Mebust’s^® excellent ductility at low temperatures. Notched Izod impacts were determined in blends containing 20% impact modifier.

Our pelletized impact modifiers have <0.05% moisture and are free-flowing. This improves handling characteristics and minimizes flammability concerns associated with the handling of impact modified powders. ABUST^® and MEBUST^® have been used by compounders in the Automotive, Furniture & Appliance, Wire & Cable, and Construction Industries where high impact strength at sub- zero temperature is a pre-requisite.
