TiO2 for Plastic Masterbatch Producers
Masterbatch producers run high-load TiO2 compounds (50–70%). Thermal stability and clean extrusion are top priorities.
Typical volume
500–10,000 t/year per masterbatch producer
Qualification cycle
4–8 weeks for commodity MB; 8–12 weeks for engineering plastics
Business context
Plastic masterbatch producers — Ampacet, Clariant Masterbatches, Avient, RTP Company — supply concentrated white pigment to plastic converters globally. The masterbatch typically contains 50–70% TiO2 in polyolefin carrier, formulated for downstream let-down at 1–5% in finished plastic parts.
Procurement challenges
- 01Twin-screw extruder throughput at 60%+ TiO2 loading
- 02Volatiles control (< 0.30%) to prevent downstream defects
- 03Compatibility with slip/antiblock additive packages
- 04Engineering plastic thermal stability (300°C for ABS, PC compounds)

Common questions
Can SEMITI 996 run 70% loading in PE masterbatch?+
Yes — qualified in customer trials at 65–70% loading on Coperion and Berstorff twin-screw extruders. Dispersant package (calcium stearate + PE wax) is essential at high loading.
