Q

PEI Medical Sterilization Discoloration

A

The thousand-cycle-level sterilization tolerance of PEI medical parts is an advantage; method differences must be verified separately; cycle records support life management.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Production & Quality PEI;medical;sterilization;color;cycle;verification

Q

Poor PEI Colorability

A

PEI coloring limitations are determined by the material's natural color; the dark color route is a pragmatic choice; color expectation management is communicated in advance.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PEI;coloring;amber;light color;color;base color

Q

PEI Chlorinated Solvent Corrosion

A

The chlorinated solvent taboo of PEI chemical resistance is a clear knowledge point; solvent management in medical scenarios is a quality link; compatibility verification cannot be omitted.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recu...
