Most of thermoplastics material are susceptible to heat degradation, which produce carbides in the processing machines. It is especially true when the machine go through start-up and shutdown, during which the screw does not rotate, and heat remaining in the screw was  built to an extent that will eventually lead to carbonize of the processed material. Formulated with highly effective ingredients, PlasE Clean PE carbon purging compound for carbon prevention by sealing screw and barrel, and resisting oxidation of itself. The material help users improve production efficiency, cut purge time and reduce scrap rate.   

PlasE Clean purging compound is formulated to resist heat degradation and carbonization, Carbides in the pictures are from a extruder which went through downtime maintenance.
