Polycarbonate Tubing for Medical Applications
Polycarbonate tubing is commonly used in medical tubing applications that require excellent optical clarity, high impact resistance, and high light transmission (88%). It is also suitable for electrical applications thanks to its high heat resistance and dielectric constant of 2.9.
Properties of Polycarbonate Tubing
Polycarbonate tubing is rigid, with good toughness. It can undergo large plastic deformations without cracking or breaking. It is comparable to acrylic tubing for its optical clarity, but is far less brittle. Polycarbonate tubing can also be compared to PETG (polyethylene terephalate glycol), also known as polyester. Both materials have similar optical clarity and light transmission.
Extruded polycarbonate tubing is suitable for many secondary processes, such as pad printing, forming, machining, overmolding, and adhesive or solvent bonding.
Polycarbonate is a lightweight, amorphous polymer that does not have a defined melting point, but rather a softening zone that beings at 297°F (147°C). Polycarbonate tubing is USP Class VI, as well as ISO 10993 compliant, and may be sterilized by steam.
DUKE Extrusion’s Polycarbonate Tubing
DUKE Extrusion offers polycarbonate tubing that is extruded to our customers’ specifications, with a typical lead time of 7-9 business days for single lumen extrusions and 2-3 weeks for custom multi-lumen extrusions. We manufacture polycarbonate tubing in a range of sizes, with outer diameters from 0.010” to 0.500”.
