Cyanate Ester (CE)
Stiff material with high temperature resistance
With a 231°C heat deflection temperature, strength, and stiffness, CE 221 is perfect for applications that need long term thermal stability. CE is comparable to glass-filled nylon.
Sample Uses:
Under-the-Hood Parts
Electrical Components
Heat Dissipation or Transfer
Autoclave Sterilized Parts
