Putting vitrimers (resin possessing dynamic covalent bonds with associative bond exchange mechanism)into practical use for electronic materialsNew high-heat resistant, eco-friendly adhesive sheet is solvent-free; can be distributed at ambient temperatures
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.
