PurgeX
Description
PurgeX® is a mechanical purging agent that enables the safe, effective and efficient cleaning of plastics processing equipment.
- Metal surfaces are cleaned using a unique scrubbing effect. The material is not abrasive to screw, barrel, die etc.
- Particularly useful when changing colour, polymer, or when screw and barrel are carbonized. Enables rapid purging of the previous colour and/or polymer, so that machine downtime and loss of expensive polymer is minimized.
- Suitable for injection moulding, extrusion and blow moulding processes.
- Cost effective, as only a small amount is required, usually at 20% add rate to the polymer.
How PurgeX® works
PurgeX® is a granular material that is blended in with a small amount of the polymer that you are using and fed into a starved screw/barrel.
The blended material is processed through your equipment at similar temperatures and revs to typical run conditions for the carrier polymer.
The PurgeX® material softens slightly, but does not melt, and thoroughly loosens carbonized and degraded resin, allowing the polymer to flush out the system.
This makes it particularly useful for:
- Cleaning colour from your equipment
- Cleaning polymer from your equipment
- Removing carbon build-up and black specks
- Regular preventative maintenance
- Before manual cleaning
- PurgeX® T for injection moulding (except where openings are less than 1.5mm)
- PurgeX® S for extrusion, blow moulding, and injection moulding with openings less than 1.5mm
- PurgeX® R for hot runner systems with a minimum clearance of 0.75mm
PurgeX® A provides a gentle scrubbing effect to the screw and barrel and removes build up of carbonised material.
PurgeX® A softens but does not melt, therefore it provides a scrubbing effect – it does not scratch or wear the screw or barrel.
- Adjust temperature if necessary. Suggested temperature range for purging is 240-260°C.
- Starve screw and barrel of current material.
- Add PurgeX® A in slow, continuous manner into hopper.
- Flush out PurgeX® A with next material to be processed.
