Carbon black noodles: carrier-free black concentrate
Hyper, Double and Master grades for plastics compounders who granulate in-house. No carrier resin, broad polymer coverage and formulation control that stays with you. Made to order.
Two-stage use — check this first
Noodles need an in-house compounding step. Step 1: mix noodles with the base polymer (PP, HDPE, LDPE, ABS, PS…). Step 2: compound / granulate on an extruder to make black granules. Step 3: use the granules for pipe, film, sheet, injection or blow moulding. They are not intended for direct dosing into single-stage extruders.

Noodles vs black masterbatch
| Carbon black noodles | Black masterbatch | |
|---|---|---|
| Cost | In general about 30 % lower | Reference |
| Carrier resin | None | Fixed polymer carrier |
| Polymer coverage | Broad — one product, many polymers | Resin-specific |
| Formulation control | Stays with you | Set by the supplier |
| Process requirement | In-house compounding step | Direct use |
Noodles are built from different carbon blacks to suit the compound, so quality and price follow the black inside. Tell us the masterbatch you use now and the shade you need, and we match a noodle to it.
Will noodles fit your line?
Three taps: how you add black today, your polymer and your product. You get a clear fit or no-fit, and what changes against masterbatch.
Where noodles are used
- Water storage tanks
- HDPE pipes (via compounded granules)
- Injection moulding — household & industrial
- Automotive moulded components
- Packaging films — blown & cast
- Blow moulding — containers & drums
- Engineering plastics — nylon & ABS compounds
- Wire & cable jacketing compounds
Dosage, customisation and storage
- Dosage2–4 % by weight for a standard black; final dosage established by trial.
- Packing & storage25 kg bags, palletised on request. Store cool, dry and out of direct sun. Shelf life 24 months, sealed.
