Rotational Moulding Powders

We’ve manufactured rotational moulding powders for over a decade. Our expertise in colouring plastics allows us to offer the highest accuracy and consistency with custom colours for rotational moulding. Our products have been said to surpass anything else on the market.

Rotationally Moulded Kayak

Our high-quality roto powders offer accurate custom colours with competitive prices and fast lead times. We’re proud of our industry-leading colour control measures. Our entire process is managed in-house, so we have complete colour control over all materials we manufacture. Our colourists have successfully developed over 1,000 custom colours for our rotational moulding customers. As well as creating custom colours, we also have a standard range of over 20 rotational moulding powders including mottle effects for millstone, sandstone, white marble, and green marble.

Free samples of our powders are available on request. We can also supply moulded samples of our roto colours as a plaque chain, hex bin or rotationally moulded cube. Our rotationally moulded 3D sample cube is unique in the market.

Roto moulded Boats


We manufacture materials for a range of specialities including:
– Supra Linear – for kayaks, dinghies and canoes
– Tank grades
– Flame retardants
– Foams
– Anti Microbials

All our powders are ground to 500 microns so they’re suitable for many different applications including complex mouldings. We supply a variety of melt flows and density specifications to meet a range of specific requirements.

Testing Equipment


We have extensive in-house testing facilities to help ensure your products meet the needs of their end applications. These include a Xenon ARC UV tester, an accelerated weather testing station and an impact tester, built to ARM standards. In addition, we can offer an FTIR test – this allows us to test supplied components to ensure your previous materials are on spec. Unlike some of our competitors, we also have a rotational moulding machine. This allows us to test the moulding performance of materials in-house, under the correct production conditions.

Quantities & Lead Times

We have a minimum order quantity of 1200kg on custom powders. Smaller lots (in multiples of 20kg) are available in our standard colour range. Free samples are available for line trials on request. Typically, our minimum lead time for custom powders will be three weeks. Powders from our universal roto range may be available within 1-2 working days, depending on stock availability at the time. Please call or email us for current information on product availability and lead times.

We can colour a range of natural grades to cover different applications. General purpose grades offer a balance of stiffness and toughness – properties which make them well-suited to the manufacture of small to medium parts. Larger mouldings will benefit from stiffer materials, which allows some reduction in shot weight. Copolymer type makes little difference to intrinsic values such as tensile yield stress, flexural modulus and impact strength. Applications where the material may be susceptible to stress-cracking will benefit from the enhanced ESCR properties of lower MFI hexene-1 copolymers. All grades are UV-stabilised and are suitable for outdoor applications. Our testing apparatus allows us to provide further detail on UV resistance and weatherability upon request.

We monitor polymer prices regularly and have established relationships with multiple suppliers. This helps ensure our pricing is competitive, whilst also offering a flexible supply chain solution in the event of shortages. Turnaround times can vary depending on our production schedule. Please call or email us for the latest details on current lead times, our team will always be happy to provide a reliable and honest update.
