PX2 Grade
Superior High Temperature

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.

Processing Temperature Range:

280°C-420°C (535°F-790°F)


    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.

    • 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.
