ProcessingInjection MouldingAdditivesRelease agentSpecial characteristicsLaser MarkableProduct TextCelanex 3202-2LM is a 20% glass-fiber PBT that is enhanced for improved laser marking graphics. It also has has an excellent balance of mechanical properties and processability. It contains an internal lubricant for mold release.
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.
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.
Storage
For subsequent storage of the material in the dryer untill processed (<= 60 h) it is necessary to lower the temperature to 100 oC.
