Match heat to resin
Processing temperatures vary widely by polymer, so specify a pigment heat rating that covers your hottest resin and residence time.

Pigments for Plastic Injection Moulding
Pigment recommendations for plastic injection moulding with technical checks and export enquiry support.
Injection moulding colours a huge range of polymers, so organic pigment selection depends heavily on the resin, its processing temperature and part geometry. Pigments must be heat stable for the melt, must not migrate or bloom in the finished part, and critically must not cause warpage or distortion in semi-crystalline polymers. Buyers should confirm the pigment's heat rating against the resin's processing window, its dispersion behaviour at short residence times, and whether a masterbatch or dry-blend delivery gives more consistent colour than powder in a fast cycle.
At a glance
What Pigments for Plastic Injection Moulding covers
Warpage-safe grades
In semi-crystalline resins, some pigments nucleate crystallisation and distort parts; choose non-warping grades for dimensionally critical mouldings.
Migration control
Confirm pigments resist blooming and plate-out so moulded surfaces stay clean and adjacent parts are not stained in service.
Masterbatch versus powder
Pre-dispersed masterbatch usually gives more uniform colour at fast cycles than dry powder, reducing streaking and specking in thin sections.

Answers
Pigments for Plastic Injection Moulding — frequently asked questions
Why does the polymer matter more than the pigment alone?
Each resin has its own processing temperature, crystallinity and chemistry, which dictate whether a pigment is heat stable, migration free and warp safe in that system. The same pigment can be ideal in one polymer and unusable in another, so selection always starts from the specific resin.
How do I avoid warped or distorted mouldings?
In semi-crystalline polymers like polyolefins and nylon, certain organic pigments act as nucleating agents, changing shrinkage and causing warpage. Specify grades tested as non-warping in your resin, especially for flat, thin or dimensionally tight parts, and validate on production tooling.
Is masterbatch better than powder for injection moulding?
Often yes. Masterbatch pre-disperses pigment in a carrier, giving consistent colour, less dust and fewer specks at short injection cycles. Powder and dry-blend can work for large batches and cost savings, but demand good mixing and screw design to avoid streaking.
What is plate-out and why does it matter?
Plate-out is pigment or additive depositing on mould surfaces and screws over a run, causing gloss defects and colour drift. Migration-prone pigments worsen it. Choosing low-migration grades and correct dispersion reduces mould cleaning downtime and keeps colour consistent across a long production run.
