Q
Random copolymer polypropylene extruded products mechanical properties substandard
Q
Random copolymer polypropylene extruded products excessive gel/gel particles
Q
Random copolymer polypropylene extruded pipe bending deformation
A
Pipe bending is caused by non-uniform cooling or haul-off eccentricity, and needs to be solved from cooling uniformity and equipment alignment.
