About VECSTAR™
What is Liquid Crystal Polymer (LCP)?
Liquid Crystal Polymer (LCP) is a class of thermoplastic synthetic resins characterized by highly ordered, linear molecular chains in the molten state. It is classified as a super engineering plastic.
LCP is widely used in a variety of applications, including base materials for printed circuits in electronic devices such as smartphones, tablets, and PCs, as well as automotive components. It is also used for precision injection-molded parts, including connectors and sockets.
Key Properties of LCP
LCP exhibits the following properties derived from its unique molecular structure:
- High flowability
- Excellent dimensional stability
- High rigidity
- Low coefficient of linear expansion
- Superior gas barrier performance
- Low water absorption
- Good vibration damping
What is VECSTAR™?
VECSTAR™ is Kuraray’s liquid crystal polymer (LCP) film, engineered using proprietary film-forming technology. It combines the inherent advantages of LCP with film-specific performance, making it particularly suitable for high-frequency electronic applications and advanced printed circuit materials.
Structure and Features of LCP
The exceptional performance of LCP is attributed to its molecular structure, in which rigid, rod-like polymer chains align in an ordered manner even in the molten state. This unique structure enables a combination of high mechanical strength, thermal stability, and excellent electrical performance, making LCP an ideal material for demanding applications.
