PE Masterbatch
Direct Answer
PE masterbatch is pigment or additive concentrated in a polyethylene carrier. The carrier must match your resin class: HDPE, LDPE and LLDPE lines each need their own carrier grade, not a generic "PE" one.
Start here if you are comparing families across polyethylene. Go straight to the resin page if your line is fixed:
- HDPE Masterbatch — blow moulding, pipe, drums, jerry cans.
- LDPE Masterbatch — soft film, shrink, coating.
- LLDPE Masterbatch — stretch and heavy-duty film.
A HDPE-carrier masterbatch let down into an LDPE film line is the classic cause of gels and unmelts, so declare density class and MFI on the enquiry.
What Is PE Masterbatch?
PE Masterbatch is a concentrate — pigment or functional additive dispersed in a Polyethylene carrier resin — used to color or modify PE parts during processing.
Typical Processing Methods for PE
Blown Film, Cast Film, Injection Molding, Blow Molding, Extrusion (pipe, cable), Rotomolding.
Grade & Concentration Notes
- Melt-flow matching. PE covers a wide density and MFI range (LDPE/LLDPE/HDPE). Specify density class and MFI so the carrier matches — a HDPE carrier in an LDPE film line causes gels.
'PE Masterbatch' is a family; for tighter matching use the specific pages: HDPE, LDPE, or LLDPE Masterbatch.
Typical Applications
Films (shopping, agricultural, shrink), bottles, drums, jerry cans, pipe, cable jacketing, rotomolded tanks, closures.
