Purging compounds

One of the best ways to avoid damage to machinery is to use purging compound during shut-down and startup. Familiarity of this compound will be a guide for the proper soak time. Often it is acceptable to purge with a safer material, such as linear low density polyethylene (LLPE). [Pg.165]

Ground/cracked cast acrylic and PE-based materials are the main purging agents, but others also are commercially available for certain machines and materials. Cast acrylic, which does not melt completely, is suitable for virtually any resin. About one pound for each ounce of injection capacity will be needed (5-10 Ib/in. of screw diameter in an extruder). With extruders, special conditions and preparations are required, which suppliers of the purging compound can recommend (remove dies, screen packs, etc.). [Pg.67]

The units are also designed to effect a rapid (or crash ) cooling of the injection unit in the event of an un-programmed interruption in the operation of the cycle. The rapid cooling ensures that the rubber does not begin to cure in the injection unit before it can be safely removed or replaced with a purging compound. [Pg.34]

Purge material should not be re-used. Re-used purge compound may work some of the time, but it will prove a false economy, through the re-introduction of cured rubber into the system. Examples of purge compound formulations are to be found in Appendix 7. [Pg.48]

It is recommended that a base resin of the same type be used as a purging compound since other compounds may not be compatible with the flame resistant compound. [Pg.273]

Examination is required in the case of nozzle and cylinder for hold up points. Feed contamination has to be eliminated and no stoppage in the check ring will help to eliminate the problem. Finally purge the machine with the purging compound. [Pg.95]
