EX Grade is our strongest-cleaning purging compound for thermoplastic injection molding and extrusion machines. EX Grade is glass-filled to provide excellent scrubbing of carbon and / or color deposits while especially designed to leave less purging compound residue behind. EX Grade is suitable for purging a wide range of commodity, engineering, and super-engineering resins. EX is especially recommended for helping prevent machine overhauls or for facilitating screw-pulls if they are mandatory.
Resins Purged:
- Most commodity and engineering resins within the processing temperature range.
Tips for purging with ASACLEAN EX Grade:
- EX Grade is ideal for hard to purge resins requiring maximum deposit removal
- Generally NOT recommended for hot runner cleaning and sealing due to its glass content
- For Extrusion, screen packs (mesh) should be removed when purging
- EX Grade should not be left idle in a machine, at any temperature, for longer than 30 minutes
Applications:
- Carbon/Color Contamination
Processing temperature:
- 390 to 680°F (200 to 360°C)
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.
