NH Grade
Injection Molding Hot Runner Cleaning

NH Grade is a mechanical purging compound especially formulated for effective hot runner cleaning. NH grade is suited for color and material changes for thermoplastic injection molding and injection blow molding machines.


Processing Temperature Range:

180°C-330°C (355°F-625°F)

    Features

    NH works particularly well for:

    • Injection molding hot runner cleaning
    • Preferred injection blow molding - OEM endorsed
    • Clear resins

    Benefits

    • Ideal for injection blow molding
    • Injection molding hot runner cleaning
    • Non0abrasive, non-agglomerating polishing filler

    • Suitable for difficult color & material changes
    • No chemical reaction 
    • No soak time required

    Applications

    Usage Information

    Temperature Range 180°C-330°C (335°F-625°F)
    Minimum Clearance Requires a 0.75mm (0.030') clearance for hot runner gates and extrusion dies.
    Amount of Purge Typically 1-2 system capacities (actual amount depends on degree of contamination
    Applications

    Injection Molding - including hot runners

    Extrusion - profile, sheet. blow molding, cast film & compounding

    Types of Resin Most commodity and engineering grade resins within the processing temperature range

    Tips

    • For maximum performance, Asaclean® NH Grade should not be diluted with other materials.

    • Asaclean® NH Grade does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge. 

    • Asaclean® NH 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.
