Q-FLEX® is the registered trade name for a variety of elastomeric compounds designed
by Flexan for the hearing aid industry. It can be processed as a molding or extruding compound in a number
of colors and hardnesses. This compound has excellent acoustical dampening properties in the mid-range frequencies.

Typical properties of the basic molding compound are:
| Durometer | 45 |
| Tensile | 1000 psi |
| Elongation | 700% |
| Tear | 80 pli |
Compression Set (22 hrs\125 °C): 32%, Solid
Heat Resistance (22 hrs\150 °C):
| Durometer | -2 |
| Tensile | -10.2% |
| Elongation | -8.4% |
Oil Resistance: (70 hrs\125 °C):
| ASTM Type | #1 | #3 |
| Durometer | -8 | -15 |
| Tensile | -13.0% | -32.8% |
| Elongation | -11.6% | -19.6% |
