Benzoxazine

It is a new thermosetting resin that reacts with various resins.

Benzoxazine is a thermosetting monomer, and cured products with high heat resistance and good electrical properties can be obtained by itself or in combination with other resins. In addition, since no by-products are generated during curing, it is difficult for voids to occur, and cured products with good dimensional stability and adhesiveness can be obtained.

Benzoxazine

JBZseries

Benzoxazine “JBZ series” is a solid thermosetting resin that applies our specialty resin synthesis technology. A cured product that is tough and has excellent heat resistance can be obtained by thermally ring-opening polymerization of the oxazine ring in the molecule. It can be copolymerized with various resins and is ideal as a curing material for epoxy resins. JFE Chemical accepts customization of various physical properties and functionality according to customer’s wishes.
