Features
Excellent compatibility to olefinic resins.
UP Grade's polypropylene-based purging compound is a match for those olefinic-based agents in injection molding and extrusion.
Easily displaced by olefinic resins.
UP Grade features high-level purging to and from polypropylene-based resins within the processing temperature range.

Usage Information
| Temperature Range | 170°C to 300°C (340°F to 570°F) |
| Minimum Clearance | 0.5 mm (.020") clearance for hot runner gates and extrusion dies; works best with screen packs removed. If screen pack removal is not possible, use the max 100 mesh size. |
| 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 & compounding |
| Types of Resin | Purging to and from polyethylene-based resins within the processing temperature range |
Tips
- For maximum performance, Asaclean® UP Grade should not be diluted with other materials.
- Asaclean® UP Grade does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge.
- Asaclean® UP 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.
