The viscosity of
Fuel Car decreases significantly when the temperature increases. Increasing the temperature of PSABS is also beneficial to reducing the viscosity during molding.
The influence of shear speed: effectively increasing the shear speed of
New Car plastics can reduce the viscosity of New Car plastics, but there are exceptions for some New Car plastics, such as PC, whose viscosity is almost unaffected by the screw speed.
The influence of pressure: The influence of New Car pressure on viscosity is relatively complex. Generally, the viscosity of PP&PE is not greatly affected by pressure, but the influence on PS is quite significant. In actual production, on machines with more complete equipment, attention should be paid to the role of high-speed injection, that is, high shear speed, and the pressure should not be increased blindly.
