--- title: Proactive & Reactive Purging description: Processors who use purging compounds are usually either proactive or reactive. Proactive purging involves a purge program which limits downtime and improves process efficiency. Reactive purging usually takes place once you find contamination or carbon issues that come through in bad parts. image: https://www.asaclean.com/hubfs/AI-Generated%20Media/Images/this%20image%20depicts%20a%20yellow%20street%20sign%20with%20arrows%20pointing%20left%20and%20right%20indicating%20a%20fork%20in%20the%20road-1.jpeg --- [ Order Online ](https://asaclean.my.site.com/b2bstore) [ Free Sample ](https://offers.asaclean.com/free-sample) ## [ Asaclean Blog ](https://www.asaclean.com/blog) Browse by Topic " aerospace asaclean asaclean news Asaclean® benefits asahi kasei automotive Best Practices black specks blisters blow molding blown-film extrusion buyers caps and closures carbon contamination cast-film extrusion Chemical Purging Compounds clear applications Color Changeovers Company News compounding consumer products contamination Cost savings custom molders Customer Success Story decreasing scrap defects electronics Energy Efficiency EX Grade extruder cleaning Extrusion fillament glass filled Glitter Grade Selection HDPE High and Low Temp Changeovers hold a bubble Hot Runners Injection Molding Injection Molding Tips LDPE Lightweight automotive components LLDPE low residue maintenance Material Changeovers Mechanical Purging Compounds medical Melt Flow Index NPE 24 nylons on the fly packaging PCR PEEK Polypropylene Post Consumer Resins preventative preventative purging processing tips profile extrusion Purge Program purge programs Purge Training Purge Trial purging purging compounds purging concentrates purging procedures Purging Tips quality recycled resins residue issues scrap reduction Screw Pulls sheet extrusion shutdown and sealing start-up super engineering resins Sustainability Tech Day technical support training trials Troubleshooting Twin Screw twin screw extrusion two step purging U Grade ULTEM venting Viscosity webinars wire extrusion -

Proactive processors use purge to optimize efficiency and purge before problems arise to keep running good parts with limited downtime.  Reactive processors only use purge when there is a production issue like black specs or streaking. While we supply both types of users, we strongly encourage everyone to implement a regular purge program to get the most out of your process. If you purge for every color or material change, you are proactive in that you are utilizing your CPC for preventative maintenance.  When used for every material or color change, it is doing a preventative maintenance.  Not only does the purge help quickly go from one job to the next saving valuable down-time, it also removes amorphous carbon before if leads to a contamination problem or carbon deposits.  Also, proactively using purging compounds improves part-to-part quality with fewer rejects. As illustrated through years of customer [CSAs (Cost Savings Analysis)](https://www.asaclean.com/why-asaclean/cost-savings-calculator/), it is exponentially more cost effective to use a purge compound in a proactive manner than to rush and use purge when you are already faced with major problems. Furthermore, waiting until you contamination issues could end up necessitating otherwise unnecessary screw pulls. If you want to establish an effective purge program, [work with a Purging Expert](https://offers.asaclean.com/free-consultation) to select a grade and learn best practices for how to use it. Then isolate one machine in the plant to apply this practice while using the CSA form for every changeover for some period of time.  Once you’ve documented the success and established a standard operating procedure for purge use, then it can easily be applied to other machines throughout your plant.    It’s great to keep an eye on price, but often cutting corners will end up costing you over time.   ![Tom Hanvey](https://www.asaclean.com/hs-fs/hubfs/Tom%20Headshot.jpg?width=150&name=Tom%20Headshot.jpg) #### [ Tom Hanvey ](https://www.asaclean.com/blog/author/tom-hanvey) Tom Hanvey is the Associate Director of Marketing & Sustainability at Asahi Kasei Plastics North America.
