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
