Stress Cracking of PEEK

Although PEEK has excellent chemical resistance, the superposition of stress and media can still cause cracking; annealing is a reliable post-treatment for eliminating internal stress; eliminating stress concentration through structural design is the fundamental measure.

Rapid Decay of Corona Treatment on PE Film

PE corona is extremely 'time-sensitive': printing right after treatment is an iron rule, and slip agent exudation is an invisible killer; the dyne value should be managed as a dynamic indicator that decays over time.

HDPE Large-Diameter Pipe Sag

HDPE large-diameter pipe sag is a system problem of 'material + cooling + process': low-Sag bimodal material is fundamental, strong cooling is the key, and die pre-offset is only a compensation means; if the wrong grade is selected, no adjustment afterwards can meet the standard.
