Liquid Crystal Polymers

What are Liquid Crystal Polymers?When melted, conventional semicrystalline polymers have a random structure, which, as they cool, form highly ordered crystalline regions surrounded by an amorphous matrix. LCPs take this order to another level. LCP molecules remain well-ordered even in the melt and slide past each other easily under shear. The result is very low melt viscosity making it easy to fill extremely thin walls and to replicate intricate features. They exhibit little or no shrinkage in the flow direction and require very little time to set up or solidify. Quick fills and shorter cycle times mean increased productivity. Injection-moldable liquid crystal polymer products have proven successful in a variety of applications, including connectors, antennas, CPU sockets, compact camera modules, sensors, small e-motors, medical devices, dental tools and surgical instruments. Unfilled polymers can be extruded for film or sheet, co-extruded for barrier packaging or melt spun for applications needing high-performance fibers or yarn.

Featured LCP Grades Vectra | Zenite LCP is a family of halogen-free, high-performance polymers that provide high-temperature performance in eco-friendly applications with exceptionally precise and stable dimensions. To meet future connectivity requirements, we’ve expanded our Vectra and Zenite LCP to offer tailored dielectric constant (Dk) and dissipation factor (Df) value, consistent Dk/Df value across wide range frequency or harsh condition and platability. Zenite liquid crystal polymer (LCP) Three new featured LCP grades: Zenite LCP 350LDS, LCP 450 LDS, and LCP 451P have been added to the LCP portfolio. The key features of LCP in all three grades are heat resistance, low moisture absorption, superior flow and intrinsic flame retardance. Zenite LCP 350 LDS: This grade is designed for miniaturization of antenna, sensor and connector. It can be used in thin wall, and with injection molded antenna application, and is LDS capable, SMT solder capable, V-0 flammability, and low warp capabilities. Key features include: High mechanical strength and high HDT Consistent Dk/Df in wide range of temperature and frequency Low dielectric constant and low dissipation factor Enable design freedom and miniaturization Low dissipation factor, reduce power consumption and heat

Zenite LCP 450 LDS: A high-performance liquid crystal polymer with excellent bonding strength.It is an injection moldable LDS capable LCP designed suitable for thin wall antenna. Key features include: 2-3X bonding strength over Vectra LCP E845i LDS Superior mechanical strength Excellent surface Maintain UL94 V0 SMT Capability Low Warpage

Zenite LCP 451P: A high performance injection moldable LCP designed for miniaturization of antenna, sensor, and connector. This grade offers excellent surface appearance without compromising mechanical strength. Zenite LCP 451P features include: Consistent plating High weldline strength High thermal conductivity and high HDT Maintain UL94 V0 Enable broadband mmWave antenna
