Features
General purpose meets cost-effective
C Grade’s styrenic-based cleaning power is suitable for simple changeovers and as part of a preventative Purge Program. C Grade is a cost-effective option for jobs where residue and severe contamination aren’t a concern.
Purges most commodity and engineering resins.
C Grade has a wide service temperature range encompassing most commodity & engineering resins.
C Grade purging compound is also safe for hot runner cleaning, as well as sealing and shutting down machines to prevent carbon on start-ups.

Usage Information
| Temperature Range | 180°C to 330°C (355°F to 625°F)* |
| Minimum Clearance | 0.5mm (0.020") for hot runner gates and extrusion dies; for extrusion screen packs, nothing finer than 100-mesh screen packs may be used. |
| Amount of Purge | Typically 1-2 system capacities (actual amount depends on degree of contamination) |
| Applications | Injection Molding - includes hot runners Extrusion - profile, sheet, cast film & compounding |
| Types of Resin | Most commodity and engineering resins within the processing temperature range |
Tips
-
For maximum performance, Asaclean® C Grade should not be diluted with other materials.
-
Asaclean® C Grade does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge.
-
Asaclean® C 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.
