It is a lasermarkable grade available in an anthrazite color to mark light-colored / white. The grade is specially formulated to yield crisp marks when subjected to a Nd:YAG laser or equivalent lasers operated at 1064nm or 532nm. Lasers operating in the UV region (355nm) may yield different results.Product information

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 <-30掳F (-34掳C) at 250掳F (121掳C) for min. 4 hours.

Mold Temperature 150-200 (65-93) deg F (deg C)
Back Pressure 0-50 psi
Screw Speed Medium
Injection Speed Fast
Injection speed, injection pressure and holding pressure have to be optimized to the individual article geometry. To avoid material degradation during processing low back pressure and minimum screw speed have to be used. Overheating of the material has to be avoided, in particular for flame retardant grades. Up to 25% clean and dry regrind may be used.
Processing NotesPre-Drying
To avoid hydrolytic degradation during processing, CELANEX PBT 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掳F (-40掳C) at 250掳F (121掳C) for min. 4 hours.
Storage
For subsequent storage of the material in the dryer until processed (<= 60 h) it is necessary to lower the temperature to 100掳 C.
