Two Ticona polymers for complex components

Unique polymers combination of liquid crystal polymer-polyphenylene sulfide alloy blends from Ticona for use in electrical and electronic components and other products.

Ticona, the engineering polymers business of Celanese Corporation, is offering two liquid crystal polymer–polyphenylene sulfide (LCP-PPS) alloy blends that combine the properties of both materials to meet the needs of complex electrical, electronic and industrial components.

The new grades, Vectra* V140 and Vectra* V143XL, improve on PPS by nearly eliminating flash, providing better flow at relatively low injection pressures, and giving high strength in thin walls. They also have mold temperatures of 80° to 120°C, versus the 135°C typical of PPS. Compared to LCP, the new grades offer higher weld line strength and less warpage in many geometries.

Uses for the new grades include connectors, bobbins, housings, switches, breakers, sensors and other high-tolerance, thin-walled parts. The grades are compatible with lead-free solder in surface-mount and other applications. In one case, a connector manufacturer adopted Vectra V140 alloy blend to meet demanding flatness specifications in products having exceedingly complex geometries and high pin counts.

The new alloys retain the physical and mechanical properties of LCP and PPS. For instance, Vectra V140 has a tensile stress at break of 1450 MPa, a flexural strength of 230 MPa and a compressive modulus of 16,000 MPa.
