A: Vocal problems, like polyps, are not restricted to singers. While singers require peak performance of their voice, other voice professionals, such as teachers, lawyers, clergy, salespeople and receptionists, are also at higher risk for many vocal cord problems.
The permissible operating temperature range of nitrile rubber is â40 to +100 Â°C (â40 to +210 Â°F). For brief periods, temperatures of up to 120 Â°C (250 Â°F) can be tolerated. SKF also offers a special nitrile rubber compound with a temperature range between â55 and +110 Â°C (â65 and +230 Â°F).
The closer that your material is to the limit of your rubber temperature range, the faster the material will degrade. Also, notice that Silicone has high rubber temperature resistance and also great low rubber temperature resistance.
