Black Masterbatch
Carbon black masterbatch for PE, PP, PET, Nylon, PC, ABS and 8 more polymers. A deep, even black with fine dispersion, and UV-stable grades for outdoor products.
What is black masterbatch?
Black masterbatch is carbon black pigment that has been fully dispersed in a carrier resin and cut into granules. You mix a small percentage into your polymer during moulding, extrusion or spinning to make the product black. Carbon black also absorbs UV light, so the same masterbatch protects outdoor products from sunlight.
Two things decide its quality: jetness, which is how deep and rich the black looks, and dispersion, which is how finely the carbon black is broken up. Poor dispersion shows up as specks, streaks, blocked filters and weak spots in the part.

Why our black masterbatch
What a good black does for your line and your product.
-
01
Deep, even jetness
A rich black with no grey or brown cast, the same across the whole part. High-loading grades reach full blackness at a low dosage, which keeps your cost per part down.
-
02
UV protection built in
Carbon black absorbs UV light at the surface, which is why black is the standard colour for outdoor pipe, mulch film and shade nets. We make UV-stable black grades for products that spend their life in the sun.
-
03
Fine carbon black dispersion
Carbon black is one of the hardest pigments to disperse. We break it down on twin-screw extruders, so there are no specks or streaks, fewer screen-pack changes on film and fibre lines, and no weak spots in the part.
Black masterbatch for every polymer
Each grade is made on a carrier that suits the polymer it goes into. These are the most common; tell us yours.
| Polymer | Typical products | What we focus on | Datasheet |
|---|---|---|---|
| PE & PP | Pipes, mulch and agri film, garbage bags, woven sacks, raffia, moulded parts | Jetness at a low dosage; UV protection outdoors | Ask for grades & TDS |
| PET | Fibre and yarn, sheet, bottles | Holds up at PET processing temperatures; even colour in fibre | Ask for grades & TDS |
| Nylon (PA6, PA66) | Yarn and fibre, automotive and engineering parts, cable ties | Deep black with fine dispersion, so parts keep their strength | Ask for grades & TDS |
| PC | Electrical housings, automotive and lighting parts | Glossy, deep black that holds at high temperatures | Ask for grades & TDS |
| ABS | Appliance and automotive interior parts, housings | High-gloss jet black for visible parts | Ask for grades & TDS |
| PBT & POM | Connectors, switches, gears and clips | Fine dispersion for precision parts | Ask for grades & TDS |
| HIPS & GPPS | Houseware, appliance parts, packaging | Even, streak-free black | Ask for grades & TDS |
| EVA, PLA, PBAT, PMMA | Footwear, compostable film and bags, acrylic sheet | Made to suit your grade and process | Ask for grades & TDS |

How to choose the right black masterbatch
Once we know your polymer, two choices decide the grade. Not sure? Tell us your product and we'll recommend one.
1. How much carbon black?
Higher loadings give the same blackness at a lower dosage, so you use fewer kilos per tonne. Lower loadings are more forgiving to dose. Our standard grades are 30% and 40%.
2. With or without filler?
Filled grades cost less per kg and suit thick moulded parts and general black products. Unfilled grades give the deepest, glossiest black and are the right choice for thin film, fibre and visible parts.
Processes

- Rotomoulding
Applications
Wherever a product needs to be black, opaque or protected from sunlight.
Frequently asked questions
What is black masterbatch used for?
To colour plastic products black and protect them from UV light. Common uses are pipes, mulch and agri film, shade nets, garbage bags, ropes and yarn, and automotive, appliance and electrical parts.
Which polymers can you make black masterbatch for?
PE, PP, PET, Nylon (PA), PC and ABS, plus EVA, GPPS, HIPS, PBT, PMMA, POM, PLA and PBAT. Each grade is made on a carrier that suits the polymer it goes into.
What dosage of black masterbatch should I use?
For colour, usually 0.5% to 2%. Products that need a set carbon black content for UV protection, such as pipes and outdoor film, take more. Tell us your polymer, product and requirement and we'll recommend a grade and dosage.
How much carbon black is in your black masterbatch?
Our standard grades have 30% or 40% carbon black, with or without filler. Other loadings are made to order.
What is jetness in black masterbatch?
Jetness is how deep and rich a black looks. It depends on the type of carbon black, how much of it is in the product and how well it is dispersed. Better dispersion gives a deeper black at the same dosage.
Do you make UV-stable or conductive black masterbatch?
Yes. We make UV-stable black grades for outdoor products such as pipes, agri film and shade nets, and conductive and antistatic grades for ESD and electronics applications.
What is the minimum order for black masterbatch?
There is no minimum order for standard grades. Custom grades start at 50 kg. Black masterbatch is packed in 25 kg bags.
Can you match my current supplier's black?
Yes. Send us a sample of the masterbatch or the finished part and we'll match its jetness and tone on your polymer. Trial samples are usually ready in 2 days.
