Q
Ovality of linear low-density polyethylene pipes exceeding standard
Q
Mechanical properties of linear low-density polyethylene extruded products not meeting standards
Q
Excessive gel/gel particles in linear low-density polyethylene extruded products
Q
Bending deformation of linear low-density polyethylene extruded pipes
A
Pipe bending is caused by non-uniform cooling or haul-off eccentricity and needs to be solved from cooling uniformity and equipment alignment.

Q
Wrinkles appearing in linear low-density polyethylene blown film
Q
Die marks/lines appearing on linear low-density polyethylene extruded products
A
Die marks are caused by die inner wall damage or impurities; the die condition needs to be regularly cleaned and inspected.
