Process: Injection Moulding; Injection Blow Moulding; Extrusion Blow Moulding; Extrusion Profile; Extrusion Sheet; shut down; start up

Resin: ABS, HDPE, PE, PP, PVC-Flexible; PVC-Rigid, TPE’s, TPO’s

Equipment: Hot runners, Cold Runners, Check Valves, Nozzles, Accumulators, Melt Pumps, Extrusion Dies

PURGEXTM 457: –

Created for more challenging colour and/or material changes. PurgexTM 457 Plus works particularly well in removing the low to mid-range material as well as glass filled resins. This grade is safely processed through hot runner gates as small as 0.75mm.

Temperature Range: 190ºC – 290ºC

Process: Injection Moulding; Injection Blow Moulding; Extrusion Compounding; Extrusion Blow Moulding; Extrusion Profile; Extrusion Sheet

Resin: ABS, HDPE, Nylon, PBT, PC/ABS, PE, POM, PP, PU, PVC-Flexible, PVC-Rigid, TPE’s, TPO’s, PET, PC, PPO, PS, SAN, PMMA

Equipment: Hot Runners, Cold Runners, Check Valves, Nozzles, Accumulators, Melt Pumps, Extrusion Dies

PURGEXTM 459: –

This grade is ideal for use with Engineering Polymers and has extra strength over PurgexTM 457 Plus. Created for more challenging colour and/or material changes. PurgexTM 459 Plus works particularly well in removing the low to mid-range material as well as glass filled resins. This grade is safely processed through hot runner gates as small as 0.75mm.

Temperature Range: 190ºC – 290ºC

Process: Injection Moulding; Injection Blow Moulding; Extrusion Compounding; Extrusion Blow Moulding; Extrusion Profile; Extrusion Sheet

Resin: ABS, HDPE, Nylon, PBT, PC/ABS, PE, POM, PP, PU, PVC-Flexible, PVC-Rigid, TPE’s, TPO’s

Equipment: Hot Runners, Cold Runners, Check Valves, Nozzles, Accumulators, Melt Pumps, Extrusion Dies

PURGEXTM 461: –

Designed for blown film applications, PurgexTM 461 cleans the extruder, screen pack housing and die/manifold, removing all types of contamination and improving overall film appearance.

Temperature Range: 120ºC – 230ºC

Process: Monolayer Film, Extrusion Sheet, ECM

Resin: LDPE, LLDPE, MDPE, HDPE, PP and Compostibles

Equipment: Blown Film and ECM Multi Caivty Moulds, extruder, screen pack housing and die/mainfold. 

PURGEXTM 602: –

Specifically designed for clear resins, PurgexTM602 Plus efficiently removes residual contamination from the screw and barrel in injection moulding machines and extruders and effectively cleans hot runner systems.

PurgexTM 602 Plus performs fast and efficient colour and material changes with PC and PS resins and their copolymers. It greatly reduces the haze that is often left after purging with polyolefin-based purging compounds.

The active ingredients in PurgexTM 602 Plus help prevent degradation of the polystyrene carrier.

Temperature Range: 190ºC – 290ºC

Process: Injection Moulding

Resin: ABS, PC, PS

Equipment: Hot Runners, Cold Runners, Check Valves, Mixing Nozzles

PurgexTM can be used in production facilities that are manufacturing food contact components. All 6 active ingredients in Purgex concentrate are Food & Drug Administration (FDA) Code of Federal Regulations (CFR) Title 21 approved for human consumption.
