Extruded LCP rods and profiles

Large-diameter rods extruded from LCP materials are used to replace steel wire. Many advantages are also gained in using LCP rods as 

Like many oriented structures, LCP rods have very small or even negative coefficients of thermal expansion, which reduce stresses caused by temperature variations. Other favourable properties are their good chemical resistance and almost zero water uptake. 

Melt-extruded members are also used as support for optical fibre cables, and are produced in different geometries to give different types of support for the optical fibre bundles. The polymers used have a modulus in the range of 60 GPa, a tensile strength of 700 MPa and an elongation at break of 1-5% in the longitudinal direction.
