Definition & positioning
What jobs fits UB
UB is a mechanical purging compound for PE blow molding, including injection and extrusion running PE-based resins. Fits color change, material change, carbon cleaning and shutdown and sealing preparation
- Process
- PE blow molding; injection including Hot Runner; extrusion profile, sheet, blown film and compounding
- Resin
- PE-based resins; TDS states PP use possible
- Temperature
- 170–320°C
- Objectives
- Color change, material change, carbon residue and shutdown and sealing
- Hot Runner
- Usable with minimum 0.5 mm passage
- Glass Fiber / Additives
- TDS notes inorganic additives below 20%, type unstated
- Soak
- Not required
- Residence / Screen
- Max 30 min residence above 280°C; screen packs no finer than 100 mesh
Limits before use
Never over 320°C; verify Hot Runner and die passage, and never use screen packs finer than 100 mesh
Check on site: Real PE grade, temperature, system capacity, clearance, screen mesh and residence time
Basic operation
Basic usage
- Confirm resins before and after purging are PE-based resins and temperature sits within 170–320°C
- Verify passage of at least 0.5 mm and screen packs no finer than 100 mesh
- Feed UB per trial plan; TDS states no soak
- Chase UB out with PE and check color or residue before production
