UP Grade Purging Compound

UP Grade is an olefinic-based purging compound designed for polypropylene and polyethylene color and resin changes for thermoplastic injection molding and extrusion machines. UP Grade is especially suited for fast and effective purging of hot runner systems.

arrow Polypropylene-Based arrow Excellent compatibility with olefinic resins
arrow Easily displaced by olefinic resins
arrow Resins Purged: Purging to and from polypropylene-based resins within the processing temperature range.

Processing temperature: 340°F to 570°F (170°C to 300°C)
UP Grade requires 0.020″ (0.5 mm) clearance for hot runner gates and extrusion dies; works best if screen packs are removed, however, if not possible use the maximum 100 mesh size.

Tips when using ASACLEAN:

arrow ASACLEAN does not work by chemical reaction.
arrow No soak time or hold-up time is required for an effective purge
arrow For maximum performance, ASACLEAN should not be diluted with other materials.
arrow ASACLEAN works best with maximum agitation. Use the maximum safe screw speed and for injection molding also use maximum safe back pressure with the screw in the most forward position.
