Abstract
Methods for extrusion of polyolefins () that control specific energy input to the extruder () for gel reduction. Disclosed herein is an example method for forming plastic products () with reduced gels, comprising: melting a polyolefin resin () in extruder () to form a melt; adjusting specific energy input in the extruder () to reduce gels in the melt; and forming the melt into a polyolefin product (). Disclosed herein is also an example method for forming plastic products () with reduced gels, comprising: melting a polyolefin resin in extruder () to form a melt; selecting a throttle valve () position for gel reduction; setting the throttle valve () at the selected throttle valve () position to restrict flow of the melt out of the extruder (); and forming the melt into a polyolefin product ().
