PX2 Grade – High Temperature
Purging Compound For Thermal Stability
PX2 Grade purging compound excels in purging super-engineering resins at processing temperatures of up to 420°C (790°F). PX2 Grade is the most powerful high-temperature grade for hard-to-clean resins.
PX2 Grade Purging Compound Features
- Produces low levels of smoke and odor.
Px2 Grade generates low levels of smoke and odor across the entire operating temperature range of 280°C to 420°C (535°F to 790°F).
- PX2 Grade features superior cleaning power.
This purging compound grade is used exclusively for purging super-engineering, high-temperature resins such as PPS, PEEK, LCP and PEI.

Tips For Proper Usage Of PX2 Grade ASACLEAN
- For maximum performance, ASACLEAN should not be diluted with other materials.
- ASACLEAN does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge. v
- ASACLEAN works best with maximum agitation – use the maximum safe screw speed and, for thermoplastic injection molding, also use maximum safe back pressure with the screw in the most forward position. (Mechanical Purge Grades)
- PX2 Grade should not be left idle in the machine at any temperature for any period of time.
- For nozzle hang-up or check ring cleaning (carbon and/or color deposits), use short, high-velocity shots.
- Do NOT use PX2 Grade for hot runner cleaning and sealing due to its glass content.
Purging Compound Process Pinpoint Diagnosis
When you run into a problem with residue, high reject rate or carbon buildup, you can’t afford lots of downtime in your production process.
Enter: ASACLEAN’s Process Pinpoint Diagnosis.
Your Purging Process Expert is usually able to diagnose whether it’s a machine or contamination issue after having a conversation over the phone. Your expert doesn’t just analyze symptoms, but adopts a holistic approach to your entire process.
Once we diagnose the root-cause issue, we send you a purging compound sample and detailed instructions so you can test out the new solution.
