EX Grade Purging Compound
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. |
 |
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 |

Processing temperature: 390°F to 680°F (200°C to 360°C) Please speak to a Technical Sales representative for further information on hot runner gate and extrusion die clearances. 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. |
