Vespel®

Vespel is a frequently-used polyimide material, often found in use with valves. While often adequate for use in systems where the chemicals do not go out of the pH range of 1 to 10, Vespel is susceptible to alkaline attack. This means that ammonia, hydrazines, amines, and any solution that surpasses pH 10 should be avoided. Also, strong oxidizing agents should be avoided or at least used with caution.



Temperature Range up to 200° C
Thread Strength Excellent
Oxygen Permeability N/A
pH Range 1 - 10
Sterilization Techniques gamma irradiation
Autoclavable? Y
