With vast experience and the latest pigments to hand, our expert colourists provide the highest possible accuracy and consistency with your colours. Their deep understanding of pigments, dyes and polymers, combined with modern colouring technology allows the delivery of accurate and cost effective masterbatch formulations. Our custom colours can be combined with special effects from our impressive portfolio and we can incorporate performance enhancing additives and processing aids.
We’ll ensure compliance with your required regulatory standards, whilst seeking to minimise costs with intelligent raw material choices. Not only accurate and cost-effective, but efficient too – custom colour requests can be matched within three to five working days and production orders are typically dispatched within just five working days of an approved sample. Our team have formulated over 50,000 custom colour matches, so you can be sure your request is in safe hands.
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.
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.
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.
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.
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.
PPHO / PPCO
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.
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.
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.
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.
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.
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
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.
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.
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.
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.
