What Electra Polymers does

Electra Polymers Limited is a privately held UK specialty chemicals company founded in 1984 in Kent, England, focused on advanced polymer-based resists, inks, and coatings for the global electronics manufacturing industry. The company serves three primary verticals: printed circuit board (PCB) manufacturing, printed electronics, and wafer-level packaging (WLP). Its core technology spans UV-curable acrylates and urethanes, thermal-cure epoxies and acrylics, polyimides, and photoimageable polymers, with notable proprietary platforms including the EMP110 aqueous photoimageable soldermask series (in production since 1987), the Durashield V42 thermal-cure epoxy family, the Ronascreen UV-curable product line, the ELECTRAJET inkjet material family developed in conjunction with Agfa, and the ED-series conductive carbon, silver, and dielectric pastes serving printed/flexible electronics applications.

The company's product portfolio is organized across roughly twelve PCB material categories (soldermasks, etch and plate resists, legend inks, filling and plugging materials, peelable resists, flexible coverlays, and inkjet materials), five printed-electronics categories (carbon/silver pastes, dielectric pastes, ITO replacement materials, etch/plate resists, cleaners), and a wafer-level packaging line (photodielectrics, passivation resists, developers) with bespoke contract R&D. Manufacturing is anchored at the purpose-built Roughway Mill facility in Kent (up to 2,000 tonnes per annum high-volume capacity plus 10 tonnes per annum specialty capacity), with a regional sales and technical-support office in Bangalore, India (the largest supplier of inks and coatings to the Indian PCB industry) and additional staff in Thailand. Approximately 90% of output is exported through a distributor network spanning over 40 countries.

Electra operates a primarily product-sale model with quote-based B2B pricing on standard off-the-shelf lines (e.g., EMP110, Durashield, Ronascreen, ED-series) layered with bespoke contract R&D and joint development agreements for customers requiring customized chemistries, often under multi-year NDAs. The company is founder-controlled, with three of the original founders (Nick Heesom, Chris Wall, Clive Landells) still active in the business, and holds ISO 9001:2015 (25+ years continuous), ISO 14001:2015 (zero non-conformances), ISO 45001:2018, UL 94V-0, REACH, and RoHS certifications. It received the Queen's Award for Exports in 1997.
