TPU and thermoplastic masterbatch

The solid-carrier format, for a process that melts. Pelletized concentrate that meters with the natural resin at the throat and disperses in the melt.

Home Products P.A.T. Products TPU and thermoplastic masterbatch

A process that melts its resin takes a solid colorant. Masterbatch is pigment concentrated on a carrier resin and pelletized, so it meters alongside the natural pellets at the throat and disperses in the melt as the screw does its work.

The carrier resin is the compatibility question, and it is the one worth settling first. A masterbatch carried on a resin that does not belong in your polymer shows up as poor dispersion, streaking, or a mechanical property you did not intend to change. Tell us the polymer and the grade family and the carrier follows.

The same shade is matched across both formats. A part run as a molded thermoplastic and a companion part cast in urethane can be held to the same standard, which is what a customer with a mixed assembly actually needs.

This lane is straightforward on the supply side because masterbatch is a format PAT sources and matches independently of the liquid dispersion book.

Typical properties

PropertyTypical value
FormPelletized solid concentrate
CarrierA resin selected for compatibility with the polymer being colored
Color toleranceΔE 1.0 or better, CIELAB against the approved standard, D65 illuminant, 10 degree observer
Let-down ratioSet by pigment loading and the opacity wanted, confirmed at the sample stage
ProcessesInjection molding, extrusion, blow molding and compounding
Match turnaroundAbout a week on a new match
Cross-format matchingThe same shade held across masterbatch and liquid dispersion

Dosage: Set by the concentrate loading and the opacity you need, and confirmed at the sample stage against your polymer and your process. A higher-loaded concentrate lets down further and costs less to run, but it asks more of the screw.

Typical values from the manufacturer's technical data sheet. They describe the product, they are not a specification. We will send the current TDS and the batch documentation your qualification needs.

Applications

TPU extrusion

Hose, tube, profile, film and sheet, where the color often identifies the grade.

Injection molded TPU and thermoplastic parts

Molded-in color on a part that never sees paint.

Compounding

Color added at the compounding step alongside the other additives.

Footwear components

Soles, uppers and midsoles, including the coyote and black defense shades.

Wire, cable and jacketing

Color-coded by circuit, rating or customer convention.

Mixed assemblies

A molded part and a cast part held to one shade across two very different processes.

It is specified where the formulation needs the right format for a process that melts its resin, carrier resin selected for the polymer rather than assumed, the same shade held across masterbatch and liquid dispersion, no liquid handling on a line that is not set up for it, ΔE 1.0 or better with the reading on the certificate, and free samples and no minimum to trial one.

Handling and dispersion

Meter the concentrate with the natural pellets at the throat, or through a gravimetric feeder where the line has one. Dispersion is done by the screw, so screw design and residence time both matter to the result.

Settle the carrier resin before anything else. Compatibility with your polymer is what decides whether the color disperses or streaks, and it is not a detail that can be fixed later by turning the loading up.

Dry the concentrate on the same terms you dry the natural resin. A moisture-sensitive polymer does not stop being moisture sensitive because the pellet is colored.

Judge the shade on a molded or extruded part from your own tool at your own melt temperature. Thickness, gate and cooling all change how a thermoplastic reads.

Packaging, storage, and regulatory status

Package sizes: Bags, boxes and larger packs. Tell us the volume and the pack and we will confirm.

Storage: Store dry in the original sealed container. Treat it with the same moisture discipline as the natural resin it will run with.

Made in the United States and supplied as Berry Amendment, REACH, RoHS and California Proposition 65 compliant, which makes it usable as a Berry-compliant component for military and government footwear and textile work. Name the requirement and we will confirm the documentation.

Frequently asked questions

Masterbatch or liquid color?

The process decides. A system that melts its resin, so extrusion, injection molding or compounding, takes a solid concentrate. A system that is liquid until it cures, so cast urethane, plastisol, foam or spray, takes a liquid dispersion. The comparison is worked through on the masterbatch page.

What carrier resin will it be on?

One chosen for compatibility with the polymer you are running. That is the question to settle first, because a carrier that does not belong in your polymer shows up as poor dispersion or streaking and cannot be fixed by raising the loading.

Can you hold the same shade across a molded part and a cast part?

Yes, and it is a normal request from anyone with a mixed assembly. The standard is the same and the tolerance is the same; the formulation differs because the format does.

What let-down should I plan for?

It depends on the concentrate loading and the opacity you need, and we set it at the sample stage against your polymer and your process. A higher-loaded concentrate lets down further and costs less per part but asks more of the screw.

Is it Berry Amendment compliant?

Yes, made in the United States, and that is why it is usable on military and government footwear and textile work. The statement ships with the documentation.

Can I get the TDS and SDS for TPU and thermoplastic masterbatch?

Yes. We send the Technical Data Sheet (TDS), Safety Data Sheet (SDS), Certificate of Analysis, Berry Amendment statement, Proposition 65 statement, and REACH and RoHS statement on request, in the current revision. Use Request TDS or SDS above and tell us what your qualification review needs.
