Material Notes:
Celanex 3226 is a non-exuding, 20% glass-filled, flame retarded polybutylene terephthalate (PBT) which has an excellent balance of mechanical properties and processability. It is well suited for electrical connectors and maintains its UL ratings with up tTo avoid hydrolytic degradation during processing, CELANEX resins have to be dried to a moisture level equal to or less than 0.02%. Drying should be done in a dehumidifying hopper dryer capable of dewpoints
