UP Grade is an olefinic-based purging compound designed for polyproylene 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.

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

	Color Changes		U, EX, E, SX, PX
	Material Changes		U, EX, E, SX, PX
	Hot Runner Cleaning		U, E
	Shutdown/Sealing		U, E
	Clear/Low Residue Applications		E, U
	High Temperature Resins		SX, EX, PX
	Low Temperature Resins		E
	Carbon/Color Contamination		EX ,U

Processing temperature: 340°F to 570°F (170°C to 300°C)
UP Grade requires a 0.020″ (0.5 mm) clearance for hot runner gates and extrusion dies; 100 mesh is required for extrusion screen packs.

Tips when using ASACLEAN:

	ASACLEAN does not work by chemical reaction.
	No soak time or hold-up time is required for an effective purge
	For maximum performance, ASACLEAN should not be diluted with other materials.
	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.
