InChemRez Hydroxy-Purge 8C is a thermoplastic organic resin alloyed with inert minerals designed to efficiently and effectively clean conventional reciprocating screw molding systems. The organic thermoplastic resin is characterized as a tough and ductile thermoplastic amorphous polymer having excellent thermal stability and wetting characteristics.

Hydroxy-Purge 8C offers a light to intermediate level of "scrubbing" characteristics for use at temperatures between 350 and 560°F. Typically, four pounds per diameter inch of Hydroxy-Purge 8C is recommended for standard cleaning (refer to InChem publication "Instructions For Use In Injection Molding Equipment" for complete list of parameters and use suggestions).

Hydroxy-Purge 8C is highly effective because:

• the proprietary formulation works under high agitation to dislodge contaminants;

• formulation contains resins and agents to wet out pigments efficiently resulting in short cleaning cycles;

• of less adhesion to internal metal surfaces.

FDA Status of Hydroxy-Purge 8C
InChemRez Hydroxy-Purge 8C is intended for use as extruder purge compounds. The resinous portion of Hydroxy-Purge 8C is compliant with numerous FDA requirements including coatings for direct and indirect food contact (21CFR175.300), adhesives (21CFR175.105), and as a component for articles intended for repeated use producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food (21CFR177.2280).

The inorganic portion of Hydroxy-Purge 8C is compliant with the guidelines of 21CFR182.2727, i.e., Generally Recognized As Safe (GRAS).
