Nuances régulières
With a huge color masterbatch library and our top of the line high-tech color lab matching system, you are assured you will get exactly the color you need, when you need it.
Tons de pastel
Light colors with heavy white content, generally opaque.
Couleurs fluorescentes
Very bright hues, popular in toy applications.
Couleurs mouchetées
Popular in light grays and tans providing a contrasting speckled color, usually black specks or fiber. This effect can be done practically on any base colors however light colors lend themselves to more dramatic effects as they contrast more noticeably against the usually darker speckles.
Couleurs métalliques
Gold, bronze, copper, aluminum and sivel effects
Couleurs de Pearlescent
Providing wonderful sheens and effects much like mother of pearl.
Couleurs irisées
Colors and effects that appear different depending on the angle of reflection of light. Can be incorporated in many shades to yeld drammatic effects such as soap bubbles. second to none.
Couleurs thermalement réactives
When incorporated in plastics will affect a change in color when exposed to heat or cold. Usually used in novelties, however some very technical applications have been achieved using these unique colors. These can be designed so that specific colors are apparent at specific target temperatures. Ambient temperatures as well as target temperatures can also be dialed in to meet specific needs.
Couleurs transparentes
Tints from light to dark that are always transparent, these formulations are generally specifically used in clear polymers.
Couleurs phosphorescentes
Colors that cause plastics to glow in the dark.

Light Fast Pigments

Pigments not predisposed to fading when exposed over long periods of times to UV light. These pigments are generally used for outdoor applications. Not to be confused with UV stabilizers, Light Fast pigments must be selected if fading is to be avoided, whether or not the resin matrix has a UV additive in it (which protects against yellowing and/or polymer degradation when exposed to UV light) Pigments, which are light fast, retain their color despite their exposure, whereas non-light fast pigment will tend to dull and actually fade in terms of pigmentation when exposed

Heat Stable Pigments

Pigments that can withstand high processing temperatures. Pigments, which lack heat stability, will burn when processed in temperature ranges exceeding their temperature window. This burning of pigment manifests itself as darkening and dirtying of the desired color. Resins that are processed at high temperatures require pigments that are heat stable so that they not change colour

Food Approved Pigments

In applications where the plastic part manufactured has an intended use in which it comes in contact with food, formulations must contain only pigments which individually are food approved. Additionally the formula once established must be submitted to government regulatory bodies to establish their suitability in the intended application.

Heat Metals Pigments

Some yellow and orange pigments known as either Lead Chromates or Cadmium pigments. These pigments are economical to use, however there is some concern with their use in certain applications due to their heavy metal content. Clients can request heavy metal free formulations.

Thermally Reactive Pigments

Pigments, which by design, will change from one color to another when exposed to heat or cold. Generally used in novelty items


Materials we incorporate into concentrate form to enhance the functionality of a particular resin in one form or another. UV stabilizers enhance performance by extending the life expectancy of a plastic product when exposed to UV light. Antistatic agents will dissipate static charges either on simple levels in a product or on higher levels, to enable the usage of the intended product in high-end electronic packaging applications. Antiblocking agents, slip agents, foaming agents, nucleating agents, antimicrobial are other additives that can be used in one form or another to achieve certain desired effects.

Composite Concentrates

Master Batches formulated to yield more than one single function. Unicolour designs composite concentrates that include multi-additive packages or a colour coupled with an additive. Speak with your Unicolour sales representative to best design a product best suited for your own unique application.

Universal Concentrates

A Master Batch, which can be utilized with a wide variety of different resins. The term is a misnomer of sorts; a more accurate way of calling such a product would be Multi Polymer Concentrate or Master Batch. True universality does not exist, however certain resins even if not of the same family as the target resin, can exhibit acceptable compatibility in low usage ratios, with little or no detriment to the ultimate product or process. It is always the responsibility of the client to determine the true suitability of a “Universal Concentrate” in any given application. They are practical in as much as their use can eliminate double inventorying of coloring media in a project where more than one resin is being used on two or more separate parts. One must be conscious of the fact that a given Universal concentrate used with one resin may yield a different appearance when used with another resin. This difference is caused by the different natural color of the base resin, which ultimately contributes to the appearance of the final product.


The phenomenon of a colour differing in appearance under different light sources.

Resin Color Contribution

Many resins have a natural color of their own. Some, for example Acrylic (PMMA), Polycarbonate, or Crystal Styrene (GPPS), are clear and colorless, while others, such as Polyolefin, High Impact Polystyrene, ABS and most other resins, have their own natural color, which affect any pigment formula. This can cause shifts in color if the same formulation is used with different base resins. This color shift can even occur if a processor changes their resin source. In cases in which a color is very sensitive, it is advisable to provide Unicolor with a sample of the new resin to be processed so that we can make the appropriate corrections or modifications if required. In certain cases resin color contribution can cause the impossibility of achieving certain shades. For example certain colors may require a formula that is 100% void of any white influence. High Impact Styrene through its rubber content has considerable white content, which would make such a formula impossible to attain.

Processing Aids

Enhances processibility of your product.


Non pigment which though addition will add opacity to your product.

UV Stabilizers

For chemical modification enhancing a polymer resistance to UV light. Such products depending on selection will prevent yellowing as well as protect the polymer from degradation due to UV exposure. Used in products designed for outdoor use.


Protects polymers against demage caused by process heat, and oxidation.

Antistatic Agents

By virtue of incompatibilty with the target resin, these products migrate to the surface of the product depositing a fine layer of moisture facilitating dissipation of static charges. Used in products where static buildup is to be prevented such as electronic packaging media.

Slip Agents

Modifies the linear coefficient of friction such that films slip with little friction against each other.

Antislip Agents

Modifies the linear coefficient of friction such that films do not slip against each other.

Antiblocking Agents

Reduces blocking of films through their addiction.
