Blown film & mulch film
Black film for agricultural mulch, construction membrane and packaging. Dispersion matters most here — agglomerates show up as pinholes and specks on a thin gauge.

Product range
Match the masterbatch to the resin, not the other way round
The carrier decides compatibility and let-down behaviour. Start from the resin you already run, then pick the black grade for the jetness and UV protection the application needs.
01 — LDPE / LLDPE / HDPE
PE Carbon Black Masterbatch
General-purpose black masterbatch for blown film, mulch film, pipe and geomembrane. Balanced jetness and dispersion at economical loading.
N330N550N660 20–50%
02 — PP homopolymer / copolymer PP Carbon Black Masterbatch
For injection molding, woven bags, non-woven and automotive interior parts where heat stability and low odor matter.
N330N550 20–50%
03 — PS, ABS, SAN PS / ABS Carbon Black Masterbatch
High jetness grades for consumer electronics housings, appliance parts and sheet extrusion, with tight color consistency.
N220N330 20–50%
04 — PE / PP Conductive Carbon Black Masterbatch
Conductive and anti-static grades for cable sheathing, IC packaging trays and ESD-safe parts.
Acetylene blackConductive grade 30–50%
Applications
Where the black ends up
Different processes fail in different ways. A grade that runs clean on a pipe line can speck a 15-micron film. We quote against your process, not a generic catalogue number.
Pipe, conduit & geomembrane
HDPE and PP pipe where carbon black provides UV protection. Loading is specified by the pipe standard, so consistency of the black content is the whole game.
Injection molding
Household goods, crates, caps and technical parts. Fast colour development and low odour matter more than ultimate jetness.
Cable & wire
Sheathing and semi-conductive layers, including conductive grades where surface resistivity is specified.
Non-woven & geotextile
Fine denier fibre needs low filter pressure value. Oversized particles break filaments, so we screen for it.
Automotive & appliance
Interior trim and housings in PP, ABS and PS, where jetness and batch-to-batch colour consistency drive the specification.
Why buyers switch
Four things that decide whether a masterbatch supplier survives a second order
Price gets you the first container. Dispersion, consistency and paperwork get you the next ten.
How we control quality- 01
Dispersion you can actually verify
We report filter pressure value and run microscopy on request. If a batch will not disperse on your equipment, you find out from a test report — not from a customer complaint three months later.
- 02
Same carrier, same black source
Colour drift usually comes from switching carbon black feedstock or carrier resin between batches. We lock both for a running order and document the batch numbers on the COA.
- 03
Export paperwork that clears customs
COA, TDS, MSDS and REACH/RoHS statements issued as standard documents rather than favours. Non-woven and food-contact inquiries get the additional declarations they need.
- 04
Advice from someone who has run the line
We will tell you when a cheaper grade is good enough, and when the extra 5% loading will cost you more in scrap than it saves in freight.
How an order starts
From your spec to a running order in four steps
- 01
Send the application
Resin, process, let-down ratio, target black content, and the standard you must meet.
- 02
Get a grade recommendation
We come back with a carrier, black grade and loading — plus the trade-offs, in writing.
- 03
Run a trial
A trial quantity on your own line, with COA. This is where most supplier decisions actually get made.
- 04
Lock the specification
Frozen carrier and black source, agreed packaging, and a documented batch range for repeat orders.
Questions buyers ask
Before you send an inquiry
If your question is not here, ask it directly — it is faster than guessing from a catalogue.
Ask a technical questionWhat carrier resins can you match?
PE (LDPE, LLDPE, HDPE), PP homopolymer and copolymer, PS, ABS and EVA. If your process runs a blended or recycled carrier, tell us the melt flow index and we will adjust the masterbatch carrier accordingly.
What carbon black content should I choose?
Most film, pipe and molding applications run 20–50% carbon black loading. Higher loading lowers freight cost per tonne of black but demands better dispersion; lower loading is easier to let down but moves more compound. We recommend based on your let-down ratio and dispersion equipment.
Can you send a sample before I place an order?
Yes. Send the carrier resin, target loading and application, and we will ship a trial quantity for your line. Sample freight is normally at the buyer’s cost and credited against the first production order.
Which documents come with a shipment?
Certificate of Analysis for the production batch, technical data sheet, and safety data sheet. REACH and RoHS statements are issued on request. If you need third-party testing (SGS, Intertek), say so at inquiry stage.
What are your packaging and lead time options?
Standard packaging is 25 kg paper-plastic composite bags on pallets, with 500 kg or 1000 kg jumbo bags available. Lead time depends on grade and quantity; confirm at quotation stage so we can commit to a date rather than an estimate.
