New PCD-PPG Block-Copolyether Polyol for CASE Formulations

A newly synthesized PCD-PPG block copolyether polyol can be applied to coating applications that require flexibility, in solvent-free urethane compositions that require low viscosity, and in various other CASE applications.

A new polyol (PCD-b-PPG) has been synthesized that has a low viscosity of around 800-3,000 mPa·s (at 25˚C, liquid state) and is transparent due to the use of PCD as an initiator, even after storing for a long duration. The new PCD-b-PPG polyol can be applied to coating applications where transparency is required. In addition, it may contribute to other CASE applications and solvent-free urethane compositions that can take advantage of its low viscosity.

Moisture-Permeable Polyurethane Pressure-Sensitive Adhesive Addresses Needs of Wearable Devices

It is difficult to simultaneously achieve both moderate adhesion to the skin and strong adhesion to a wearable device, but a new polyurethane pressure-sensitive adhesive is providing a solution.

Wearable devices are used in medicine to continuously monitor signals such as electrocardiograms and electroencephalograms. They can also be used to monitor physical conditions during exercise. To improve the accuracy of the analysis, many studies have been conducted by directly attaching wearable devices to the skin using a pressure-sensitive adhesive (PSA) sheet.
