News Release

Toyobo Co., Ltd. and Toyobo MC Corporation have jointly developed an eco-friendly, highheat-resistant polyester adhesive sheet for electronic materials by applying a new class of cross-linked resins called “vitrimers”. This adhesive sheet is solvent-free, and can be transported and stored at ambient temperatures.

Vitrimers are a new class of cross-linked resins, which possess dynamic covalent bonds with associative bond exchange mechanism. The new product was developed by taking advantage of vitrimers’ property to respond to pressure and heat — just like thermoplastic resins — while maintaining the cross-linked state of polymers.

Toyobo MC Corporation plans to start providing samples, manufacturing and selling the product to electronic material makers soon.
