Cel-Span® Purge 388

Cel-Span® Purge 388 is a transition purge that contains several proprietary additives that are essential in the cleansing cycle of high temperatures and lower melting polyolefins. Temperatures above 500 °F may cause material to smoke. Cel-Span® Purge 388 can be used directly without any mixing necessary to clean most plastic equipment during color and resin changes. The unique additives and resin system in Cel-Span® Purge 388 makes it possible to cleanse color resins in less time, in most resin applications.
