About PB-5903

PB-5903 process characteristics: K material low water absorption, no need for drying before processing, if K is expected for a long time in high humidity environments open storage, you need to drying (65 ℃ less), and good fluidity, easy processing, the processing of a wide temperature range, typically between 170 ~ 250 ℃, non-crystalline, low shrinkage (0.4 ~ 0.7%). K material above 260 ℃, if the melt residence time in the barrel length ( more than 20 minutes), will lead to thermal degradation, affecting its transparency, and even color brittle. appropriate "low, medium, medium temperature" condition molding, mold temperature should be between 20 ~ 60 ℃, thicker products, After removing the cooling water can be placed to obtain a uniform cooling to avoid cavitation.
PB-5903 Application: cups, lids, bottles, hinge-type boxes, clothes hangers, toys, PVC alternative feed products, food packaging and pharmaceutical packaging supplies.
