Epichem founded by Barry Leese, Managing Director, and Graham Williams, Engineering Director in 1983, has become the global leader in the supply of high purity specialty chemicals and gases for the electronics and pharmaceutical industries. The major products include trimethylaluminum, trimethylgallium, trimethylindium, silane, boron trichloride, and precursors for high k dielectrics & barrier layers. Epichem is a multifunctional company that incorporates customisable product supply, technical support, safety training, asset management, and joint projects for research and development.

Epichem employs an extensive research and development program by partnering with various companies and universities worldwide. These close alliances allow Epichem to improve our products and provide cutting edge technology solutions above and beyond standard product supply.

An expanding worldwide marketplace has led Epichem to take a global view of sales, marketing and production. Epichem originated with sales, production and research facilities located in Bromborough, Merseyside, UK. Customer and market demand influenced Epichem to establish an administrative office in Allentown, Pennsylvania, US, and a manufacturing facility in Haverhill, Massachusetts, US, which together form Epichem Inc.

In February 2000, Epichem acquired Inorgtech Limited (now Epichem Oxides & Nitrides) based in Mildenhall, UK. Epichem Oxides & Nitrides specialises in Oxide and Nitride precursors for barrier layers, high K dielectric, and ferroelectric materials used in the new generation of Silicon semiconductors.

Epichem continues to expand globally, increasing production and customer satisfaction, with the introduction of our newest facility, Epichem Asia, located in Kaohsiung, Taiwan.

Epichem is now established as a major supplier of high purity specialty chemicals and gases worldwide to the electronics and pharmaceutical industries. This success can be attributed to the development of tonnage capacity for all major products, world-class lowest detection limit analytical capabilities, and the most experienced people in the business. Epichem employs state-of-the art automated SS plants and delivery systems for the production of pyrophoric materials. The critical processes are now carried out in clean rooms by Epichem chemists and technicians.
