In the design of plastic straw black masterbatch formula, first of all, the raw materials, carbon black, additives are accord with the requirement of detection indicators of GB9688 a 88.
Because of the special pipe production technology fast linear velocity, products belong to the thin products, compatibility of black masterbatch dispersion, high requirements.

The cut surface of the suction side with Angle, hardness and toughness are required to achieve an equilibrium value.
So the carbon black content in black masterbatch is the key, should also consider the choice of carrier resin. The reason is PP crystallinity is higher.
