InstaPurge™ Commodity-Grade Cleaning Compound from NOVACHEM is a mechanical purging agent that dislodges the residues of previous production colors and resins that remain on cylinder walls and screws after the barrel is run empty. It permits these residues to be quickly removed from the machine and is then readily purged from the barrel by the next production color or resin. The machine is back to producing good parts with minimum downtime.
InstaPurge™ gains its purging effectiveness from three factors:
- The proprietary formulation works in combination with a high level of agitation during the purging process to dislodge contaminants.
- The formula includes resins and other ingredients that are effective in providing mechanical "push" over a wide temperature range.
- An exclusive ingredient in InstaPurge™ Cleaning Compound causes it to be much less tenacious than other resins of similar viscosity in its adhesion to metal surfaces.
NOVACHEM recommends InstaPurge™ for use in conventional reciprocating screw injection molding systems. It may also be used in conventional screw-type extruders. The product is intended for use with thermoplastic resins processed between 350°F and 630°F (175°C - 332°C), a range that includes all commodity resins and many engineering materials.
InstaPurge™ Cleaning Compound cleans processing equipment thoroughly, providing quick, trouble-free changeovers that allow molding shops to operate at peak efficiency. Here's how:
- Pelletized InstaPurge™ handles and feeds easily, like production material. No mixing = No mess.
- InstaPurge™ Cleaning Compound is stiff enough to displace production resins effectively at normal operating temperatures. No waiting around for heats to come up.
- InstaPurge™ does its job in a straightforward way. Just run it through as described in the simple instructions. No complicated multi-step procedures; no soak period required.
- When the job is done, all residues of InstaPurge™ Cleaning Compound are flushed from the system quickly by the following production resins. Thanks to its unique formulation the compound doesn't adhere to screw flites and barrel walls.
In sum, if you are a plastics processor that does not work with "exotic" resins or operate very large or highly complex equipment then you probably do not need (and should not pay for) a "high performance" purging compound. You need a hard-working "commodity-grade" purging material - InstaPurge™ is that material.
InstaPurge™ Filled grade gives the product additional "scrubbing" effectiveness for difficult changeovers, but extensive use over a long period may cause wear in soft metal finishes.
NOVACHEM does NOT recommend the use of the filled grade for hot manifolds.
NOVACHEM does NOT recommend use of the filled grade for extrusion equipment unless the die is removed (along with andy screens or filters).
