Everything about Masterbatches, in one place
A complete, sales-floor-ready FAQ resource on masterbatch fundamentals, lab testing, PP & PE polymer grades, customer objection handling, and application-wise use cases — with a linked video for every single question.
Masterbatch Basics
The foundation questions every trainee, buyer, or new hire in the plastics industry asks first.
Filler, Additive & Other Masterbatch Types
Understanding the difference between filler masterbatch, additive masterbatch, color masterbatch, white/black masterbatch and specialty batches.
Lab Testing & MFI (Melt Flow Index)
What quality checks a masterbatch plant runs before dispatch, and how to read the test report.
Polymers Used with Masterbatch: PP & PE (LDPE / LLDPE / HDPE)
Since almost every masterbatch is dosed into a carrier resin, understanding PP and the PE family is essential for both production and sales conversations.
| Polymer | Density (g/cm³) | Typical MFI range | Key traits | Common uses |
|---|---|---|---|---|
| PP (Polypropylene) | 0.90–0.91 | 2–35 g/10min | High stiffness, good clarity in homopolymer, high melting point (~160°C) | Woven sacks, BOPP film, injection parts, nonwoven fabric, raffia |
| LDPE (Low Density PE) | 0.915–0.935 | 0.3–20 g/10min | High branching, flexible, good clarity & sealability | Film, lamination, extrusion coating, squeeze bottles |
| LLDPE (Linear Low Density PE) | 0.918–0.940 | 0.5–6 g/10min | Linear chain with short branches, higher tensile & puncture resistance than LDPE | Stretch film, liner bags, blown film, mulch film |
| HDPE (High Density PE) | 0.941–0.965 | 0.05–25 g/10min (grade dependent) | Highly linear, high crystallinity, strong & rigid, low permeability | Blow moulded bottles, pipes, crates, woven sacks, carry bags |
