Kuraray Co., Ltd. has developed and initiated sales of two new VECSTAR liquid crystalline polymer products: CT-Z film with excellent heat resistance and FB film with superior optical reflectivity.

VECSTAR is a liquid crystalline polymer film developed by Kuraray using its proprietary film-forming technology. VECSTAR has superior electrical and high-frequency properties and heat-resistance as well as dimensional stability. Moreover, because of its low-moisture absorbency, it was primary developed as an insulating film for use in printed circuit boards (PCBs), especially high-speed PCBs. Recently, PCB development has advanced to higher frequencies, which enable high-capacity and high-speed processing owing to increases in the transmission speed of electronic data in areas such as PCs and digital cameras.

These two newly developed VECSTAR products offer higher frequency capabilities and also provide higher heat resistance and optical reflectivity than existing products.

CT-Z Film
CT-Z film has the highest level of heat resistance among commercially available liquid crystalline polymer films. Because this new film features high-frequency electrical properties, it is the material best-suited for insulating flexible PCBs and multilayered PCBs. In addition, the excellent heat resistance of CT-Z film enables the hand soldering of PCBs using high-temperature soldering iron, a capability that has been difficult for existing products to achieve, and is expected open the way for additional applications.

FB Film
FB film has superior optical reflectivity. While possessing a heat resistance compatible with auto-soldering processes that utilize lead-free solder, it also provides the highest level of optical reflectivity among commercially available liquid crystalline polymer films. Moreover, since FB film's optical reflectivity deterioration due to heat is miniscule, Kuraray will market it as a material best suited for white LED PCB applications.
