Q-Flex® Tubing and Hearing Aid Materials

Q-FLEX® is the registered trade name for a variety of elastomeric compounds designed by Flexan for the hearing aid industry. Q-Flex tubing and hearing aid materials can be processed as a molding or extruding compound in a number of colors and hardnesses. Q-Flex tubing has excellent acoustical dampening properties in the mid-range frequencies. The elastomeric portion provides a degree of chemical resistance not found in other hearing aid formulations.

Typical properties of the basic Q-Flex molding compound are:

Durometer	45
Tensile	1000 psi
Elongation	700%
Tear	80 pli

Compression Set (22 hrs\125 °C): 32%, Solid
