Custom Colours

When our laboratory receives a colour match request, our experienced colourists will select appropriate pigments or dyestuffs to formulate your colour, considering your specific requirements. A ‘labshot’ is then created using a compatible base resin. The components of the formulation are mixed and moulded to produce a colour plaque. If necessary, this process is repeated with adjustments being made until the optimum result is achieved.

A masterbatch formula is then calculated based on the customers requested addition rate (let down %). A sample is manufactured under production conditions and moulded into colour plaques which are mailed for customer approval. Once approved, these plaques form the ‘master standard’ to which all future production is referred.

Plastic seats with UV absorber additive

Performance Additives

Additive masterbatches are commonly used in plastic manufacturing to alter the physical properties of the material. The performance of plastics can be enhanced with various additives – each changing the polymer in a different way, for a different purpose. For example, a UV absorber additive is frequently used to improve the colour fastness and slow the degradation of plastic items designed for outdoor use.

Our range of performance additives can improve processing or enhance the performance of your end component. We can supply additives as a stand-alone additive masterbatch or compound, or more commonly we’ll incorporate additives into your custom coloured masterbatches. Our expert team can tailor the addition rate of the additive for your specific manufacturing conditions and end-use requirements.

Sparkle special effect masterbatch

Special effects

We offer an impressive range of special effects for plastics. These are achieved using a select group of effect pigments, used in place of or alongside regular pigments and dyestuffs. Special effects are increasingly favoured in the design of modern plastic components. In response to ever-changing market demands, our expert technical team continues to expand our effects portfolio. See our Special Effects page to find out more.

Household brands such as Nescafe, Glade, V05 and Sensodyne have utilised our special effects for plastics. If you’re seeking visual distinction for your packaging or product, then our effect masterbatches can offer you the edge over your competitors. Combined with our custom colours, the possibilities are almost limitless.

Compatibility with your polymer of choice

Our custom masterbatches are polymer specific. This means they’re formulated for high performance when dosed into your chosen material. We can manufacture masterbatches for use with all the polymers outlined below, amongst others. If you’re running a material not listed here, please do get in contact with our expert technical team to see if we can meet your requirements.


LDPE - Carrier Bags

Low-Density Polyethylene – Slightly clearer than HDPE and far more flexible, mostly used for flexible packaging, carrier bags, flexible tubes, film applications etc. Like HDPE it has restricted transparent properties. It possesses excellent chemical resistance to alcohols, acids and alkalis. Limited resistance to hydrocarbon solvents and mineral oils. It will start to degrade when exposed to UV radiation for extended periods.


HDPE – Milk Bottles

High-Density Polyethylene – Slightly opaque white appearance used extensively in rigid bottle packaging, injection moulded caps and closures, crates etc. Its inherent whiteness can restrict the level of transparency achievable. HDPE possess better chemical and solvent resistance than LDPE.


Bottle Caps

Polypropylene (Homopolymer, Block Copolymer, Random Copolymer)
PPCO Random & PPHO – Fairly clear polymer used in caps and closures. Also used to manufacture houseware products, buckets toys and storage boxes. Polypropylene is flexible with no real restrictions to colour or effects. Random copolymer is clearer than homopolymer and more suitable for translucent colours.
PPCO Block – PPCO but modified for greater impact strength. The additive turns the polymer white giving it a high level of opacity. This can restrict the transparency achievable.


PET Bottles

Polyethylene-terephthalate – Polyesters are mechanically very strong and have good chemical resistance and barrier properties. PET is commonly used for making carbonated drink bottles. In addition, polyester can be spun and used to make textiles for clothes. PET is very clear which makes it good for translucent packaging, although a slight ‘yellowness’ can affect very light tints.


Electrical Insulation

Polybutylene terephthalate – a thermoplastic crystalline engineering polymer that is often used as an insulator in electronics industries. It is a type of polyester with an excellent balance of properties and processing characteristics.


Coloured CD cases

General Purpose Polystyrene – Glass clear but with very little impact strength it is most commonly used in CD cases. Its high level of clarity makes it good for translucent colours although an occasional violet tint can be visible.


Coloured Toy Bricks – Anti Microbial

High Impact Polystyrene – GPPS with the addition of an impact modifier to give greater impact strength. This additive turns the polymer white, various grades give different levels of opacity. Generally used for games pieces, toys etc. Its high level of whiteness makes translucent colours difficult to achieve. Specialist versions such as K-Resin and Styrolux are available on the market to give the same translucency as GPPS.


Drill Housing made from ABS

Acrylonitrile Butadiene Styrene – A tougher version of HIPS used in components with a higher added value. ABS is more durable than components manufactured in HIPS although it shares its difficulties in matching translucent colours. Like HIPS specialist translucent grades are available. Due to its durability, ABS is utilised in the manufacture of casings for power tools.

PA66 / PA6

Electrical Connectors made from PA6 / PA66

Polyamide (6, 66) – Nylon is a general-purpose grade which is widely used for mechanical construction and maintenance. This is due to its optimal combination of mechanical strength, stiffness and mechanical damping properties, together with a good electrical insulating ability. This is why electrical housing is made from nylon. PA66 is commonly used as a replacement for metal in various applications, the chemical and physical properties of PA6 are very similar to PA66. PA6 has better impact resistance and solubility resistance than PA66, but its moisture absorption is also stronger.


High Gloss Packaging

Styrene acrylonitrile copolymer – Transparent and with excellent chemical resistance, heat resistance and gloss, SAN also has good rigidity, tensile and flexural strength. Due to its high gloss appearance, SAN tends to be used in cosmetic packaging applications. SAN can cause problems when colouring in light tints due to the violet dyestuffs present in it. These are used to visually ‘clean it up’ when manufactured.


Blister Pack

Polyethylene terephthalate Glycol – PET with glycol added. The Glycol is added to give better flow properties but decreases the strength. PETG can be extruded to form bottles and into sheets to make ‘blister’ type packaging.


Product made of TPE/TPU

Thermoplastic Elastomer/Thermoplastic polyurethane – TPU has many applications including automotive instrument panels, caster wheels, power tools, medical devices, and a variety of extruded film, sheet, and profile applications. TPEs are used in a variety of applications in the automotive, medical, construction, electrical, appliance, packaging, and industrial markets.

What is masterbatch?

Masterbatch is used to add colour or enhanced properties to plastic components. It’s a concentrated formula of colourants and/or effects and/or additives, combined with fillers, encapsulated within a carrier plastic resin. Masterbatch is supplied in pellet form to be dosed into raw polymer for use in plastic manufacturing. Masterbatch can be used with virgin polymer or used with recycled plastic. We encourage customers to consider using PCR (post-consumer recycled) resins wherever possible. Want to know more? Check out our detailed article for a deeper explanation of masterbatch and its incredible role in enhancing product colours. Click here to learn more!  

Why do I need masterbatch?

Anyone creating a coloured plastic item will tend to require a coloured masterbatch. Broadway can develop and supply plastic colourants in the form of masterbatches, for plastic moulders to use in production. Masterbatch is almost always the preferred choice for colouring plastics. Most coloured plastic components we encounter in our daily lives will be coloured with masterbatch. As the pigments or dyes are encapsulated within a pellet, masterbatch ensures a much cleaner process than would otherwise be experienced by using liquid colours in plastic manufacturing. This can minimise waste and significantly reduce downtime in production. It also allows very accurate control of colour dosing and distribution. It’s not just about colour though, masterbatches can also be used to achieve a number of special finishes within plastics. Additive masterbatches can improve processing and enhance the properties of end components.

Which polymers do Broadway manufacture masterbatches for?

Broadway provide polymer specific masterbatches for use in HDPE, LDPE, PPCO, PPHO, PET, PBT, GPPS, HIPS, ABS, PA66/PA6, SAN, PETG and TPE/TPU. Our Universal Colour Range is designed for use in a variety of polymers.

What let down rate should I use?

The let down you use may be dependent on the way you dose or mix your colour. Using high quality gravimetric dosing equipment it may be possible to dose as low as 1%. This means one pellet of masterbatch to every 99 (equally-sized) pellets of your raw polymer. This tends to work more effectively when moulding high volumes of components, where you have the opportunity to optimise the process at the start of a long production run. With volumetric dosing or premixing, a higher let down is desirable to achieve a consistent colour in your end components. The higher the let down you use, the greater your colour stability will be. This is especially relevant for translucent colours and can be beneficial for highly colour critical applications. Although in such instances a compounded material might be more appropriate. High let down rates (a greater proportion of masterbatch to raw polymer) will increase your overall raw material costs, as masterbatch will cost significantly more than your raw polymer. An optimal let down rate will result in lower costs, without having a negative impact on the colour consistency of your end components. A masterbatch designed for a low let down rate will tend to be ‘highly loaded’. This means the formulation will contain a greater percentage of colourant to the amount of filler or carrier resin. As pigments and dyes are expensive components in the formulation, a masterbatch formulated for a low let down rate will tend to have an increased cost per kilo, compared to a masterbatch formulated for a high let down rate. But overall savings can still be achieved as less masterbatch will be needed in production. Our Universal Colour Range is formulated for a 1% let down rate, but it can be dosed at a higher rate if required.

What is the cost of Broadway’s colour matching service?

A colour match will usually be free, we’ll do the match and post sample plaques free of charge. On rare occasions where specialist constituents are needed to complete the match then Broadway will be in touch to discuss any associated costs before we start work.

How long will it take to get a colour match?

It will usually take our team 3-5 working days to dispatch a colour match sample following receipt of a new colour match request. Our team process several matches every day, if we have an exceptionally high volume of matches to produce then leadtimes may be longer. We advise all customers to request matches as soon as they can, in order to avoid any delays.

Can I get a free sample?

In many cases, small samples can be obtained free of charge. Please call us to discuss your requirements. Postage costs for samples will be dependant on location.
