E Grade
Low Residue/ Temperature

E Grade is a purging compound for thermoplastic injection molding and extruder machines. E Grade is especially designed for residue-sensitive or low-temperature resins. E Grade leaves very little residue behind while facilitating color and material changes. E Grade is ideal for shutdown and sealing applications to ensure fast and clean machine start-ups.

Processing Temperature Range:

160°C-300°C (320°F-570°F)


    Specially designed for low-residue, low-temperature resins.

    E Grade has a low-residue formulation, and purges most commodity and engineering resins within the processing temperature range.

    May be used in conjunction with other purging compound grades.

    Whenever low residue is crucial, E Grade makes an excellent chaser to any other Asaclean® scrubbing grades' to ensure maximum cleaning with minimum residue.


    • Designed for residue-sensitive and low-temperature resins
    • Styrenic-based mechanical purge
    • Ideal for clear applications
    • Low residue purge
    • No chemical reaction
    • No soak time required


    Usage Information

    Temperature Range 160°C to 300°C (320°F to 570°F)
    Minimum Clearance No minimum hot runner gate clearance requirement nor extrusion die or mesh clearance requirement.
    Amount of Purge Typically 1-2 system capacities (actual amount depends on degree of contamination)
    Applications Injection Molding - including hot runners
    Extrusion - profile, sheet & cast film
    Types of Resin Most commodity & engineering resins within the processing temperature range, particularly clear and low-temperature resins


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