TECADUR® MT TR Rod

TECADUR® MT TR is a transparent medical grade copolyester (PCT-G) based on Tritan™ copolyester chemistry, and it is BPA-free. It is one of the few glass-clear stock shapes that combines high toughness with outstanding hydrolytic stability. Tensile strength at yield is 6,900 psi with 160 percent elongation at break and 10,500 psi flexural strength, notched Izod impact strength is 3.7 ft-lb/in, and Rockwell hardness is R118. Moisture absorption is 0.06 percent in 24 hours. Heat deflection temperature is 210°F at 66 psi and 171°F at 264 psi. The material is color stable through ETO, e-beam and gamma sterilization.

It is specified for single-use bioprocess components, pharmaceutical fluid handling, sight glasses and flow-visible manifolds, filter and sensor housings, diagnostic device bodies and clear surgical instrument components. Biocompatibility is established to ISO 10993 for blood and tissue contact, BPOG protocol extractables testing has been completed, and USP Class VI information is available for the raw material. Stock shapes machine and polish to optical clarity; use sharp tooling and flood coolant to avoid heat haze at the cut. The limits are thermal and chemical: it is not a steam autoclave material, and strong ketones and chlorinated solvents will attack it.
