Q

PPSU flame retardant performance

A

PPSU inherent flame retardancy is a safety advantage; product quality determines performance; test verifies grade.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PPSU; flame retardant; V-0; inherent; thickness; test

Q

PPSU food contact compliance

A

PPSU food contact is an advantageous application; grade and certification match; archive management handles audits.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Production & Quality PPSU; food contact; FDA; transparent; compliance; certification

Q

PPSU demolding angle

A

The 1~2° angle and large-area ejection of PPSU demolding are standard; high-temperature challenges need management; protection prevents damage.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Injection Molding PPSU; demolding angle; ejection; area; high temperature; protection

Q

PPSU nozzle selection

A

The open design of PPSU nozzles is recommended; matching is the key to quality; inspection prevents failure.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Injection Molding PPSU; nozzle; open; matching; drooling; cold slug

Q

PPSU screw design

A

The universality of PPSU screws is processing convenience; check valve design is the key detail; maintenance ensures long-term stability.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PPSU; screw; check valve; ring type; dead spot; wear

Q

PPSU injection speed fast

A

PPSU fast injection is the official recommendation; multi-stage management prevents side effects; monitoring ensures quality.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Injection Molding PPSU; injection speed; fast; multi-stage; shear; air trap

Q

PPSU mold temperature

A

The 149~163℃ mold temperature of PPSU is the supplier standard; uniformity ensures consistency; balanced optimization is based on verification.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling PPSU; mold temperature; 149℃; stress; surface; uniform

Q

PPSU melt temperature management

A

The 385℃ upper limit of PPSU is the degradation red line; transparent parts are managed more strictly; actual measurement prevents display errors.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PPSU; melt temperature; 385℃; degradation; discoloration; calibration

Q

PPSU drying temperature lower limit

A

The 135℃ lower limit of PPSU drying is an efficiency guarantee; inability to over-dry is a material characteristic; environmental humidity must be compensated.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying PPSU; drying temperature; 135℃; efficiency; hopper; humidity

Q

PPSU insufficient drying surface streaks

A

PPSU drying is the prerequisite for appearance quality; 500ppm/100ppm are different standards for '2079851475616104452/extrusion; reusability is a material economic advantage.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying PPSU; drying; streaks; 500ppm; hydrolysis stability; reuse
