Carbon black noodles: carrier-free black concentrate, 50–60 % carbon
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 | |
|---|---|---|
| Carrier resin | None | Fixed polymer carrier |
| Carbon content | 50–60 % | Typically 25–40 % |
| 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 |
