RapidPurge FDA/GRAS Chemical Grades

Available from RapidPurge

RapidPurge has expanded its product line to include a non-ammonia, non-foaming chemical/mechanical purging compound for medical and food purging applications. This new generation of purging, comprised of FDA/GRAS materials, offers both chemical and mechanical properties for effective purging of all thermoplastic resins up to 700/f plus degrees. As with all RapidPurge grades, these new RE Grades are non-abrasive and can be used to purge downstream equipment like hot runner tools and dies.

RE Grades are thermally activated purges with a softening chemistry to soften polymer structure and lower viscosity of resident resin. Degradation is softened and loosened during the purge to be pushed out with the mechanical portion of the purge. The same softening effect applies to the polyethylene base resin in RE purge material which makes it easier to clear out of the machine after the purge. The RE Grades are fully pelletized/compounded for best dispersion of active ingredients and there are no fumes or smoke omitted during the purge process. They are run through the machine at operating temperatures.

RE products are loaded with antioxidants and stabilizers that also offer excellent shutdown properties. Simply purge the machine, empty and shutdown, leaving the residual RE purge in the machine to prevent oxidation. The purge material will add stabilization during cool down/heat up offering a faster start-up that is free of black specks.
