The ULTEM® Signal Whistle features our popular Mk2 style pineapple pattern for sure grip in just about any weather conditions, rain or shine. ULTEM® stands out from other high-performance polymers because it is uniquely designed to remain mechanically stable under extreme conditions. It can withstand temperatures upwards of 217°C for extended periods of time and remain dimensionally stable in fluctuating temperatures. It is inherently flame resistant.

ULTEM® was created for use in the aerospace industry and designed to remain mechanically stable under extreme conditions. It resists stress cracking under when coming into contact with fats and oils from food, alcohols, acids, fluids used for servicing cars and aircrafts, and other aqueous solutions. ULTEM® it is also resistant to ultraviolet rays and gamma radiation (so, you know, just incase you were ever exposed).
