ProcessingInjection MouldingDelivery formPelletsAdditivesRelease agentSpecial characteristicsLaser MarkableProduct TextCelanex 3300-2LM is a 30% glass-filled PBT that is enhanced for improved laser marking graphics. It contains an internal lubricant for enhanced mold release. It is a lasermarkable grade available in a black color to mark white, The grade is specially formulated to yield crisp marks when subjected to a Nd:YAG laser or equivalent operated at 1064nm or 532nm. Lasers operating in the UV region (355nm) may yield different results
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 4 hours.
Processing
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
