Custom Compounds

We apply the same level of quality and expertise to the manufacture of custom compounds as we do to colour and additive masterbatches. Investments in modern extrusion technology enable us to manufacture large lot compounds with precision and efficiency. Integration of our high-quality masterbatches provides complete colour control and a huge range of polymers can be processed thanks to underwater pelletising.

Broadway’s precision compounds

From our 90,000 ft² facility, we produce consistent, high-performance plastic compounds with the efficiency and scale to meet high-volume demand with short lead times. Plastic compounds are often the preferred choice for moulders when colour and additive precision are critical, or when processing highly filled materials. Using pre-compounded materials can improve consistency, reduce dosing errors, and streamline production – especially useful in demanding or tightly controlled applications or where maintaining compliance is a must. We support the needs of specialist industries with tailored, high-performance compound solutions.

We compound a wide variety of polymers; polyolefins, polyesters, amorphous and styrenes. These include: PPCO, PPHO, HDPE, LDPE, LLDPE, MDPE, PET, PETG, PBT, ABS, SAN, HIPS, GPPS, PA6, PA66, TPE, TPU, PLA, EVA, PMMA, ASA, PC, PC/ABS and various biopolymers

Precision Compounding

Advanced feed integration supports the precise handling of multiple constituents. This allows complex formulations to be produced accurately and efficiently – with the inclusion of high concentrations of colours, + performance additives, and fillers.

As a plastic colouring specialist, we maintain complete colour control in house – ensuring accuracy, efficiency and repeatability in colouring your custom compounds. High throughput production lines enable large lot orders to be manufactured at speed, while retaining the flexibility to offer smaller lots too.

Underwater Pelletising

Underwater pelletising delivers consistent pellet quality and enables the efficient handling of difficult-to-process polymers and filled materials.

Unlike with traditional strand pelletising, material is cut directly at the die face, so a strand doesn’t need to be formed. This means soft and brittle polymers and filled materials (which are typically difficult or impossible to stand) can be efficiently processed and pelletised with consistency guaranteed. This technology has broadened the range of polymers we’re able to compound.

bio-sourced filler material

Bio-fillers, Biopolymers and PCR

We offer bio-filled compounds, bio-based polymers, and recycled grades to support evolving sustainability requirements. Bio-filled plastic compounds reduce reliance on oil-derived polymers by incorporating a significant percentage of sustainable, natural fillers. Many of the fillers we use are by-products of other industries, providing a use for material that would otherwise just become waste. We also offer compounds made from bio-polymers or high levels of recycled plastic content.

Toll Compounding

We provide comprehensive toll compounding services. We are equipped to handle a wide range of compound requirements with consistent quality and repeatability. If you currently free-issue your constituent materials for compounding, we’d be happy to offer a comparative quote for toll compounding your formulation.

We collaborate with leading material innovators to support the development of novel formulations. We assist with upscaling from lab-scale batches to industrial production. Whether you’re refining an existing compound or pioneering a new material, we’ll prove to be a reliable compounding partner.

Colour matching equipment

Extensive Testing Facilities

We offer comprehensive in-house testing with an extensive range of mechanical, material, and weathering test equipment – programmable to ISO/ASTM test settings. Through academic partnerships, we access a range of advanced testing services, enabling deeper insights.

We offer comparative analysis of our materials against those from other suppliers, including evaluation of UV protection performance through accelerated weathering studies. Our testing capabilities are particularly valuable for compounds, which often constitute the full composition of your moulded parts.

Contact us today to discuss your material requirements with our expert team.

Colour Masterbatch

We’ve worked with many customers to deliver custom compounds for specific requirements. Our Special Project Team reviews niche enquiries and works with our technicians and production team to engineer solutions. Continual investments in our R&D facility enable the efficient development of new additive compounds. We always take a flexible approach and provide a tailored service to best suit your needs.

Our stocked masterbatch range offers 122 colours and the flexibility of a universal carrier system, so if you need a colour compound quickly, we can compound these colours into your chosen polymer. Please call our friendly team for more information on compatibility and pricing.

When purchasing compounds from Broadway, our customers can expect the same efficiency, value, material accuracy and support services that we’ve provided to our masterbatch customers since 1997.

Which polymers can Broadway compound?

Broadway can compound many different polymers; polyolefins, polyesters amorphous and styrene polymers. These include: PPCO, PPHO, HDPE, LDPE, LLDPE, MDPE, PET, ABS, SAN, HIPS, PBT, GPPS, PA6, PA66, PETG, TPE, TPU, PLA, EVA, PMMA, ASA, PC and PC/ABS, Biopolymers (various). We can run compounds with virgin material or with high levels of PCR/PIR (recycled polymer). Broadway are able to source the required polymer, or compound with customer supplied materials.

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.

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.

How long will it take for me to get a sample?

A colour sample from our universal range can often be delivered on a next day service. If you request a sample for a custom colour match then this will typically be dispatched within 5-7 working days of receipt of that request, along with your sample plaques.

What are the minimum order quantities for Broadway’s materials?

Universal Masterbatch: 1kg Custom Masterbatch: 5kg Custom Compounds: 25kg Universal Roto powders: Small lots available in multiples of 20kg Custom Roto powders: 1,000kg

How long will it take for my order to be dispatched?

Universal Masterbatch: From one working day (dependent on current stock availability) Custom Masterbatch: From five working days (dependent on current production schedules) Custom Compounds: From five working days (dependent on current production schedules) Universal Roto powders: From one working day (dependent on current stock availability) Custom Roto powders: From three weeks (dependent on current production schedules) Please remember to allow time for delivery. Broadway deliveries are reliant on external courier services.

Can I combine stand-alone effects with my existing colours?

Stand-alone effects can be supplied and combined with your existing colours, but this might not achieve the optimum result. Not all colours and effects are compatible. If you advise our team of your requirements we can advise on a case-by-case basis. Often it’s best for us to formulate a colour and effect masterbatch for you, as opposed to you dosing effects into your existing masterbatches.
