Ticona has extended the operating temperature and flow properties of its Vectra liquid-crystal polymer.
Aimed at demanding electronics applications such as connectors and lead-free surface mounts, Vectra LCP S135 has a heat-distortion temperature under load of 635° F. The Florence, Ky., firm also said the new grade has better weld-line strength and reduced viscosity to fill walls as thin as 0.008 inch.
Ticona claims the new LCP's polymer structure allows processing at temperatures lower than other high-heat LCPs. It also can be molded at tool temperatures below 200° F, allowing use of water-cooled molds for faster cycles than in oil-cooled molds.
