U Grade Purging Compound

U Grade is a versatile, HIGH-PERFORMANCE purging compound especially suited for color and material changes for thermoplastic injection molding and extrusion machines. U Grade has a wide service temperature range encompassing most commodity, engineering, and super-engineering resins, making it unnecessary for multiple grades. U Grade is also recommended for hot runner cleaning as well as sealing and shutting down machines to prevent carbon on start-ups.

	High Performance General Purpose		Styrenic-Based
	Resins Purged: Most commodity and engineering resins within the processing temperature range.
	U Grade's cleaning power approaches that of our strongest scrubber, EX Grade, but without the glass filler. It is ideal for applications that require higher detergency while maintaining lower residue.

	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.

"The U grade not ony keeps the tips and screws clean, but eliminates the need to pull the screw for anything but regular preventative maintenance.

"This has been a major cost savings for us.

"I estimate that for this particular product line, U grade reduced restart time by 60 percent, and eliminated unscheduled screw pulls (possibly 12 per year.

"The U grade has raised the bar for all purging compounds "
