Liquid Crystal Polymer Tubing

Precision Extrusion's capabilities include Liquid Crystal Polymer extrusion. By using a patented rotating extrusion die, a biaxial orientation of the polymer occurs, overcoming the structural limitations of conventionally extruded LCP tubing. We extrude Liquid Crystal Polymer (LCP) tubing in a variety of sizes.

The grade of LCP used and the wall thickness determine the strength range of the tubing. Further manipulation of the process, will effect the stiffness, compressive strength, or other properties needed for a particular application. These special Liquid Crystal Polymer tubes typically have twice the crush resistance of today's conventional plastic tubing.

LCP tubes are a unique product that can provide significant cost and performance advantages for medical devices. Liquid Crystal Polymer tubing can be three times thinner than that formed from polycarbonate with equivalent stiffness. LCP tubing typically costs between 30 and 60% less than fiber-reinforced composite tubes with similar properties. Some applications of LCP extrusion include: endoscopic, laproscopic, and urological instruments.

LCP's advantages include the following: USP Class VI approval High melt (>500°F) and use (>400°F) temperatures Repeatedly sterilizable by autoclave, chemical, ETO, or radiation Equal or higher tensile strength (>20,000 psi) and stiffness (2.0 million psi flexural modulus) than any competing plastic Superior dielectric strength (1,100 volts/mil.)
