Q

Metallocene linear low-density polyethylene MLLDPE high extrusion torque/high energy consumption (variant: mass production scenario)

A

MLLDPE high energy consumption is caused by narrow molecular weight distribution and high melt viscosity and needs to be solved by optimizing screw design, increasing temperature and adding processing aids. In different production scenarios, targeted preventive measures need to be taken.
