Q

PBT Surface Peeling

A

The number one suspect of PBT surface peeling is contamination; regrind management and barrel cleanliness are the defense line; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBT; surface peeling; contamination; regrind; plasticization

Q

PBAT fiber spinning

A

PBAT fiber is a differentiated application; process optimization improves performance; testing verifies quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; fiber; spinning; strength; drawing; test

Q

PBAT 3D printing application

A

PBAT 3D printing is an emerging application; process parameters require fine management; verification ensures quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; 3D printing; interlayer; temperature; dimension; support

Q

PBAT static electricity problem

A

PBAT static management is the norm in film processing; antistatic and elimination are equally important; environmental control is auxiliary.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; static electricity; dust; antistatic; humidity; elimination

Q

PBAT lamination strength

A

Interlayer bonding of PBV lamination is structural performance; compatibility and process are equally important; testing verifies strength.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; lamination; strength; peeling; compatibility; adhesive

Q

PBAT printing adhesion

A

Surface treatment is the key to PBAT printing; corona is the standard method; ink matching affects quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; printing; adhesion; corona; ink; surface

Q

PBAT lubricant application

A

PBAT lubricant is a double-edged sword as a processing aid; the minimum effective amount is the principle; test and evaluate side effects.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; lubricant; migration; heat seal; printing; dispersion

Q

PBAT anti-blocking agent selection

A

Selection and dosage of PBAT anti-blocking agent is formulation technology; migration risk must be evaluated; dispersion quality affects the effect.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; anti-blocking agent; selection; addition amount; migration; dispersion

Q

PBAT melt index too low and processing difficult

A

Temperature and shear adjustment are the main means for PBAT melt index too low; lubricant is auxiliary; grade selection is fundamental.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; melt index; too low; plasticization; shear; lubricant

Q

PBAT melt index too high and blown film unstable

A

PBAT melt index management is the prerequisite for blown film stability; chain extender is the adjustment means; degradation prevention starts from the source.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PBAT; melt index; too high; film bubble; molecular weight; chain extender
