PTFE Tubing

Get to Know Techyours™ PTFE Tubing

The unique properties of Techyours™ PTFE tubing cover an impressive range. These include high use temperature compared to other polymers, almost universal chemical resistance, excellent electrical properties at high voltage and high signal frequencies, non-stick characteristics, usefulness under extreme low temperatures (cryogenic conditions), and UV resistance. However, mechanical strength and wear resistance are not criteria for which PTFE is recommended, which is one reason for the development of FEP tubing, PFA tubing and ETFE tubing.

Techyours™ PTFE tubing's high viscosity in the gel state (it does not truly melt) prevents it from being processed conventionally in extruders or injection molding. Techyours™ PTFE tubing is therefore dry molded or extruded in hydraulic extruders with (paste extrusion) or without (ram extrusion) lubricants. Paste extrusion of PTFE yields flexible tubing. However, it occurs in a batch process and thus long continuous lengths are limited to the batch size, unlike the melt-processible fluoropolymers FEP, PFA and ETFE.

Techyours™ PTFE Tubing Offers:

● Non-stick properties
● Temperature resistance up to 260º C (500º F)
● Aging resistance
● Can be steam or chemically sterilized in-line
● Superior chemical resistivity and low coefficient of friction

Techyours™ PTFE Tubing In the World

Materials Overview

PTFE

The unique properties of PTFE have made it the polymer of choice for many applications since it was discovered in the late 1930s. With the lowest coefficient of friction of any polymer we offer and an extremely broad working temperature range, PTFE is ideal for use in products such as catheters for delivery channels for medical devices and wire and cable insulation for aircraft. Because of its unparalleled chemical resistance, PTFE has become an ideal polymer for the chemical and analytical sciences.
