Polyimide material products

JFE Chemical is ready to answer

your inquiries relating to

polyimide materials.

We offer customized products

designed to meet your needs.

Polyimides have excellent heat resistance and are used for a variety of advanced-function materials in electrical and electronic applications, as well as other fields.
As a specialist in the manufacture of aromatic chemicals, JFE Chemical fully leverages the benefits of polyimides to provide its customers with optimized materials to satisfy their needs. We supply a selection of polyimide raw materials with specific characteristics, as well as customized varnish materials.


Polyimide varnishes

Our “JIV Series” of resin solutions was developed through the application of JFE Chemical’s technological strengths in the synthesis and refining of aromatic compounds.
By applying resin to a base material and then heat treating it, we can form an infusible and insoluble coating with excellent toughness and heat resistance. We supply high-quality polyimide products, produced in accordance with our own high-level raw material management system. We accept custom orders to suit specific needs for varnishes of various properties and functionality.


Polyimide monomers

JFE Chemical offers a variety of characteristic polyimide raw materials like only a specialist manufacturer of aromatic fine chemicals can.
