PM8240 | Purging Compound

Purging Compound for low viscositv and low temperature thermoplastics

Chemical/mechanical purging compound PM8240 – formulated for low temperature applications – for extrusion, injection, and blow molding machines effectively cleans and removes contamination, additives, adhesion, carbon built-up and resin residues. PM8240 is premixed, ready-to-use and conveniently applied to your machinery.

Heat activated chemical/mechanical Purging Compounds are the premium flagship product line in the RapidPurge product portfolio. PM8240 is the preferred to choice to address high degradation, difficult color changeovers, and challenging material changes.

The chemical purging compounds are specially formulated to address high degradation, difficult color changeovers, and challenging resident residue issues. RapidPurge compounds penetrate layer by layer to deep clean down to the bare metal. These products are non-abrasive and can be used to clean Injection Molding, Extrusion, and Blow Molding equipment.

The chemical/mechanical purging compounds are also excellent as a Shutdown media to eliminate black specs on startup. Simply purge the machine, empty and shutdown, leaving the residual RapidPurge with heats turned off in the machine to prevent oxidation. The purge material will not burn during cool down/heat up offering a faster startup that is free of black specks. Scrap generation on startup will become less and less with continued use

RapidPurge Chemical purging compounds include:

• Proprietary chemical agents that break down the molecular structure and viscosity of the resident resin in order to attack the adhesion of resins to metals.
• Heat-activated expanding foaming agents to reach negative flow areas.
• Specialized mechanical agents for cleaning, scrubbing, and soft polishing of the machinery’s base metal.

Heavy-duty Chemical Agents

RapidPurge's proprietary formula dissolves and removes heavy and stubborn contaminants, residue and carbon build-up. As a thermally activated cleaning solution, RapidPurge's chemical cleaning compounds increase their cleaning performance with increasing temperature. Its chemical ingredients and carrier material break down plastic residues in low-viscosity molecules, which can be easily flushed out of the machine. RapidPurge also helps protects sensitive machine parts while it does not attack metals, seals or coatings.

• Pellet Form Factor

  Chemically active ingredients are preserved inside the granules to ensure high performance for the cleaning process. With very low consumption - typically a barrel filling is sufficient to unfold full cleaning performance - and impressive purging properties, RapidPurge is the ideal product for quick, gentle, effective and economical purges for extrusion molding and injection molding machines. RapidPurge helps to reduce machine downtime by up to 90%.

• Pre-mixed

  RapidPurge is pre-mixed, ready to use and can be applied easily and without further preparation. The premixed granules contain a universal carrier material and ensure a simple and simple application. RapidPurge is suitable for hot runner cleaning, and its design allows even small openings to be passed easily. A removal of parts or downstream equipment is basically not required.

• Excellent Shutdown Properties

  RapidPurge cleans, protects against wear and supports the efficient start-up of injection and extrusion molding equipment. The purge compounds are an excellent solution for shutting down machines. Its thermal stabilizing properties effectively protect against impurities from black specs upon machine start-up.

• Maximum Results

  RapidPurge's chemical cleaning granules are developed as a thermally activated product that achieve higher performance with increasing processing temperatures. The temperature can be increased up to the maximum processing temperature of your main material to minimize machine dwell time and soak cycles even in the most demanding applications.
