Universal White Color Masterbatch for PE/PP
70% TiO2 white masterbatch for PE and PP injection molding. 25 kg bag bulk export with 50 kg MOQ. Brightness L* value 96.5 on polypropylene test plaques.
Highlights
- 70% TiO2 loading — 2-4% let-down ratio for injection molded parts, lower cost per piece than 50-60% masterbatches.
- Single masterbatch works across PE and PP lines, reducing inventory SKUs for multi-resin molders.
- Brightness L* value 96.5 on PP test plaques, yellow index below 2.0 — clean white without grey cast.
- Formulated for injection and blow molding shear conditions, not a repurposed film-grade product.
- Process stable up to 230°C with no streaking or plate-out on mold surfaces.
- Supplied in 25 kg kraft bags with PE liner, palletized and stretch-wrapped for container shipping.
- MOQ 50 kg with 5-15 day lead time. FOB Shenzhen or CIF to Southeast Asia and Europe.
- COA provided per batch with TiO2 content, MFI, moisture, and colorimetric data.

Product Detail
UNIVERSAL WHITE COLOR MASTERBATCH · 70% TiO2 · PE/PP CARRIER
Color Masterbatch for Plastics in a 70% TiO2 white concentrate, carried in a PE/PE-wax blend. This batch is built for injection molding and blow molding of polyethylene and polypropylene parts - not a film-grade product repurposed for thick-wall applications. On PP test plaques, brightness L* reaches 96.5 and yellow index stays below 2.0.
The reason 70% loading matters is let-down ratio. At 2–4% addition rate, injection molded parts reach full opacity. A 50–60% TiO2 masterbatch typically needs 4–6% to achieve the same coverage. Less masterbatch per part means lower material cost and less carrier resin diluting the base polymer. MFI is 18–22 g/10 min (190°C, 2.16 kg), which covers most injection molding machines running PE or PP.
One batch works across HDPE, LDPE, LLDPE, and PP. For a molder running bottle caps in HDPE and household containers in PP on the same floor, that means one white SKU instead of two. For buyers sourcing a Color Masterbatch for Plastics manufacturer, the practical question is whether the dispersant package holds up under injection molding shear. This batch is tuned for higher shear and thicker wall sections - it disperses evenly in the screw zone up to 230°C without streaking or plate-out on mold surfaces.

Why Buyers Choose This Color Masterbatch for Plastics
70% TiO2 at 2–4% Let-down
Full opacity at 2–4% addition rate. Compared to 50–60% TiO2 masterbatches requiring 4–6%, you use less material per part and introduce less carrier resin into the base polymer.
One SKU Across PE and PP
Works on HDPE, LDPE, LLDPE, and PP. Molders running multiple resin families on the same floor stock one white masterbatch instead of maintaining separate SKUs for each polymer.
Built for Injection Molding Shear
Dispersant package tuned for thicker walls and higher screw shear. No streaking or plate-out on mold surfaces up to 230°C - the failure mode that repurposed film-grade whites hit in injection molding.
COA with Every Batch
Each batch ships with a certificate of analysis covering TiO2 content, MFI, moisture, and colorimetric L*a*b* values. A 500 g retain sample is kept for 24 months for traceability.
Applications
Bottle Caps & Closures
HDPE and PP caps requiring clean white appearance with no grey cast. Brightness L* 96.5 at standard let-down.
Household Containers
PP storage containers, bins, and kitchenware where consistent whiteness across production lots matters for retail shelf appearance.
Blow-Molded Bottles
HDPE and PP bottles for personal care and household products. 70% TiO2 provides opacity at lower addition rates, reducing carrier resin dilution.
Injection-Molded Parts
Housings, fittings, and components where streak-free white finish and dimensional stability are required after molding.
For Color Masterbatch for Plastics OEM buyers, we coordinate let-down ratio, resin carrier, dispersion reports, and sample plaque approval before mass production. If you need custom color matching beyond standard white, our Pantone matching for 3D filament guide explains the color development workflow from target chip to production batch.
