Q

PE Film High Haze and Poor Transparency

A

PE film haze: 'adjust crystallization internally, adjust the surface externally': rapid cooling refines the grains to reduce internal haze, and eliminating melt fracture reduces external haze; for high-transparency requirements, go directly to metallocene grades, which is more effective than forc...

Q

PC sprue material cleanliness management

A

The value of regrind depends on cleanliness and heat history control; transparent and high-requirement parts should keep regrind out；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

PC Extruded Sheet Surface Gel Particles

A

PC gel particles are first divided into two categories: 'unplasticized and contamination': the former relies on plasticization and screens, the latter on cleaning and dead-corner treatment; optical sheets have extremely high requirements for melt uniformity.
