Super Engineering PlasticsManufacture and Sales of Engineering Plastics including LCP, PES, E101, Epoxy, Sumiploy® and IGETABOND™

Sumika Electronic Materials is part of Sumitomo Chemical’s global network of compound semiconductor manufacturing facilities including: production facilities in Chiba, Japan and research and development in Tsukuba, Japan.

The facility serves as the base of US operations and customer support for Sumitomo Chemical’s engineering plastics business. This includes a full line of Liquid Crystal Polymer (LCP) and Polyethersulfone (PES) resins.

Super engineering plastics are high-performance resins that have excellent heat resistance, strength, chemical resistance, and processability. 

As materials that meet the needs for lighter and finer articles, super engineering plastics include liquid crystalline polymer, which is used in the manufacture of electrical and electronic products and is expanding into applications in the industry and automobile areas, and polyethersulfone, which in addition to electrical and electronics applications is also being used as a carbon fiber composite in aircraft, as a high-performance separation membrane material, and as a heat resistant coating.

Polyethersulfone (PESU)

SUMIPLOY® series are functional polymer compounds which are noted for the highest level of sliding property as well as for high thermal resistance among thermotropic polymers.


Wholly aromatic polyester resins in SUMIKASUPER E101 Series have excellent abrasion resistance, self-lubrication properties, chemical resistance and heat resistance. When added to solid lubricants such as polytetrafluoroethylene (PTFE) resins and graphite, SUMIKASUPER E101 makes them resistant to abrasion and compression creep and improves their sliding properties.


SUMI-EPOXY ELM is special polyfunctional epoxy resins characterized by excellent heat resistance. They deliver high performance as matrix resins for sealing materials of electric and electronic parts, heat-resistant paints and carbon fiber composites (CFRP).
