Q
Gel particles/gel particles in low density polyethylene film
Q
Ovality of low density polyethylene pipes exceeding standard
Q
Bending deformation of low density polyethylene extruded pipes
A
Pipe bending is caused by non-uniform cooling or haul-off eccentricity; it needs to be solved from cooling uniformity and equipment alignment.
