William Blythe is one of the oldest inorganic chemical manufacturers in the UK. The core of our current chemistry is based around copper, tin and iodine compounds. Originally, the business manufactured chemicals for the local textile industry, since then the company has transformed itself and its products numerous times. This culture of adaptability and continual innovation remains core to the business philosophy to this day.

We have world class research facilities and a team of highly skilled scientists ready to provide inorganic material solutions for the challenges of tomorrow. We have a strong track record of taking new innovations from lab scale to industrial manufacturing.

Manufacturing

We have developed a vast amount of experience and knowledge in the production of inorganic materials. Underpinning everything we do is operation at the highest standards of quality control. This runs through both product, quality performance and service that we offer our customers. Our core capability is the manufacture of rigorously defined, high purity functional inorganic chemicals. This is achieved through a range of chemical processing routes including bi-tri metallic precipitation, redox chemistry and hydrothermal synthesis. Once the target chemical is manufactured, we have a toolkit of purification techniques that we can employ to produce high purities to specification. We also utilise post processing techniques such as blending, granulation and masterbatch production.

Chemical Development

Our R&D team have extensive knowledge of bi-metallic and tri-metallic precipitation reactions, continuous flow reactors, hydrothermal synthesis, redox chemistry, electrochemistry, calcination and purification. We’ve worked with blue-chips, start-ups and academia in developing scalable manufacturing routes to new inorganic materials.

Characterisation

Control of the physical and chemical properties of inorganic chemicals is our core capability. We have a suite of materials characterisation techniques to ensure product quality throughout scale up including SEM, XRD, XRF, ICP-OES, TGA/DSC, surface area, particle size and metal assay.

Process Scale up

When working on innovation projects for customers, we can take new process routes from gram to kilo to hundreds of kilogram quantities in our R&D laboratories. In 2022 we installed a new scale-up facility designed to take new processes to industrially relevant reactors, allowing us to supply new materials at 100’s kg quantities for pilot scale processes. 

Pilot Manufacturing

It is crucial to have flexible pilot scale manufacturing assets to transfer lab processes and demonstrate scalability. Our R&D team work hand in hand with our chemical engineers and analytical chemists to ensure that new processes are effectively and safely transferred to pilot scale manufacturing.

Application Testing

We have capabilities for lab scale testing across a range of industries including polymer processing, fire testing, gas absorbent capacity and batteries.

Quality Control

We aim to ensure the highest levels of quality in everything we do. Our Quality Management System is ISO 9001 accredited and our team strives to exceed customer expectations in quality control and customer service. Our quality control laboratory is equipped with advanced analytical techniques, enabling us to characterise the chemical and physical properties of every batch manufactured at William Blythe.

Bespoke & Custom Product 

Our multi-purpose production facility can also be employed to offer greater synthetic flexibility where smaller volumes of material are required. If your current requirements are not met by the products on our product pages, please do get in touch. Our team is keen to tackle any challenge you may have.

FLAMTARD 

Antimony-Free Flame Retardants

William Blythe is a global leader in the manufacture of antimony-free, flame retardant synergists for polymers under our brand: Flamtard TM.

Based on zinc, tin and mixed metal oxide technology (eg. zinc hydroxystannate and zinc stannate) the Flamtard TM products are synergists that offer flame retardant and smoke suppressant properties in a range of polymer systems, including PVC, polyamides, elastomers and thermosets. The Flamtard products are commonly used to replace ATO (antimony trioxide) in polymer applications such as wire and cables, roofing membranes and artificial leather.

All Flamtard TM products are non-hazardous, environmentally benign and registered globally.

Flamtard TM product benefits:

Flame retardant synergist and smoke suppressant

 

Non-hazardous technology

 

Cost-effective replacement for antimony-based flame retardant additives (eg. ATO)
