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 maximum performance, Asaclean® PX2 Grade should not be diluted with other materials.
- Asaclean® PX2 Grade does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge.
- 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.
