British Chemical Manufacturing Since 1920
Synthite has manufactured chemicals since 1920, starting from our original site in West Bromwich before relocating to Mold, North Wales in 1950. From our Mold site, we have built the scale, technical capability and product portfolio needed to support key industrial markets across the UK, Ireland and Europe.
We are the UK’s only independent producer of formaldehyde, with a manufacturing capacity of over 100,000 tonnes spread across three production plants at our Mold site. We are also a major supplier of bulk methanol, importing over 100,000 tonnes annually and supplying more than 40,000 tonnes to the wider UK market each year.
Alongside our core product range, we offer flexible toll manufacturing from our North Wales site, specialist chemical haulage via our in-house ADR-certified fleet, and a range of oilfield and speciality chemicals under the Syncide® brand.
Scale, Capability and Responsiveness
What distinguishes Synthite is the combination of internationally connected supply networks with the responsiveness of a locally managed UK operation. When specifications evolve, schedules change or technical challenges arise, we provide solutions without the delays that come from remote decision-making.
Recent multi-million-pound investment in a new formaldehyde production unit reflects a long-term commitment to UK manufacturing, reinforcing supply security and environmental performance for customers who depend on us.

Synthite Products and Services
Our core range covers formaldehyde, paraformaldehyde, bulk methanol and Syncide® speciality chemicals, complemented by toll manufacturing and bulk chemical haulage services.
An Upper-Tier COMAH Site: Safety and Compliance
Synthite’s Mold site holds upper-tier COMAH designation, reflecting the scale and nature of hazardous materials handled in our manufacturing operations. This designation means our safety management systems, emergency planning and regulatory reporting are subject to ongoing independent scrutiny by the HSE and Natural Resources Wales.

Our Operating Approach
Synthite’s operating approach is defined by safety, customer focus and resilience. This underpins the confidence placed in Synthite by industries that depend on secure and uninterrupted chemical supply.
Our long-term commitment to British manufacturing is demonstrated through ongoing investment in our facilities, our people, and the collaborative partnerships with our customers and suppliers.
Customers deal directly with the people who make and move their chemicals. When specifications evolve, schedules change or technical challenges arise, decisions are made quickly, by people who know the site and the product.
This approach has shaped our position not only as a supplier, but as a manufacturing partner.
