General name
Liquid crystal polymer film
Sales format

Vecstar™ is the world’s first liquid crystal polymer (LCP) film, developed based on Kuraray’s unique film forming technology. Its excellent electrical properties make it suitable for high-speed circuits and high-frequency electronic devices, and it is widely used as a circuit board substrate material. Kuraray has developed a broad range of applications by exploiting the superior characteristics of LCP (low water absorption, heat resistance, dimensional stability, flame retardance and gas barrier properties, and processability).
