Since starting out in 2002 as a distribution company specifically for the motorsport industry, we’ve grown significantly. Today we manufacture a wide range of epoxy, polyurethane and novel tooling materials and ancillary products, and a range of specialist low-density subsea buoyancy materials.
Based in the UK, our tooling boards and buoyancy materials are used by customers globally.
Our UK and European distribution hubs offer fast access to our tooling boards and ancillary products, and our special projects team provide bespoke support for those custom projects.
