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 t
To 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 <-40°F (-40°C) at 250°F (121°C) for 4 hours.
For subsequent storage of the material in the dryer until processed (<= 60 h) it is necessary to lower the temperature to 100° C.Information provided by Celanese Corporation. |
