Features
General purpose meets high performance.
NCR Grade is arguably the best Chemical Purging Compound on the market. It excels in extrusion, hot runners, and other low flow / low pressure environments and offers excellent cleaning power without residue.
Purges most commodity and engineering resins.
NCR Grade easily purges most production resins across a wide processing temperature range. NCR quickly removes contamination, facilitates easier changeovers, and is easily displaced by your next resin.
Benefits
- High-performance, general purpose grade
- Designed for color & material changes
- Strong cleaning action in extrusion
- Ideal for applications involving low flow or low pressure environments where foaming action is critical
- Heat-activated
- Polyethylene-based purge
- Effective when used for shutdown and sealing to prevent buildup
- Short soak for maximum effectiveness
Applications
- Color Changeovers
- Material Changeovers
- Color/Carbon Contamination
- Shutdown and Sealing
- Hot Runner Cleaning
- Preventative Purging
- Clear/ Low Reside Applications
- High Temperature Applications
- Low Temperature Applications
- Screw Pulls
Usage Information
| Temperature Range | 175°C to 360°C (345°F to 680°F) |
| Minimum Clearance | No minimum hot runner gate clearance requirement nor extrusion die or mesh clearance requirement. |
| Amount of Purge | Typically 1-2 system capacities (actual amount depends on degree of contamination) |
| Applications | Extrusion - profile, sheet, cast film & compounding Injection Molding - including hot runners |
| Types of Resin | Most commodity and engineering grade resins within the processing temperature range |
Tips
- Purge at shutdown on Friday for a trouble-free startup on Monday.
- Soak 10-30 minutes, depending on specific application.
- Maximum cleaning achieved at 260°C to 315°C (500°F to 600°F) within the processing temperature range.
