General Description:  

General Description : The reinforcement of PBT with glass fiber results in large increases in strength, stiffness and heat distortion temperatures without loss of impact strength. The normal color is off-white.

Applications include those for unfilled PBT together with high power lighting components, ignition rotors, distributor caps etc.
