Rosehill team with Flexilon-coated pipeline

35+ Years Polymer Chemistry

Developing advanced polyurethane systems since 1988. Deep formulation expertise refined over decades of subsea application.

UK Manufacturing at Scale

500+ tonnes monthly capacity from our West Yorkshire facility. Reactors from 4 to 60 tonnes for any project scale.

140°C Service Temperature

Flexilon 3604 delivers industry-leading high-temperature performance for HP/HT subsea applications.

A Materials Supplier, Not an Applicator

We supply bespoke polymer systems engineered to your project specification, for application by you or your chosen coating house. A trusted supply partner — never a competitor for your work.
