Automated Shrinkage Measurement System

 

Polyester-based polymer substrates offer new fields of applications in the area of electronics, such as flexible OLED (organic light emitting diode) displays or flexible lightning technologies.

 

During the development of polyester substrates engineers have to face the challenge that the thermal shrinkage behaviour of the substrate films has to be optimized. To meet the requirements concerning high accuracy and reproducibility and short testing times Brückner developed an automated offline measurement system for the determination of the thermal shrinkage.
