Q

PPO Steam-Resistant Part Failure

A

PPO's steam resistance advantage must be exerted within design limits; processing quality determines whether the advantage can be realized; long-term verification data guides application boundaries.; After confirming effectiveness, fix the parameters and practices into the work instruction to pre...

Q

Secondary deformation of PP products after packaging

A

PP 'packing hot parts = a source of secondary deformation': write 'cool thoroughly before packing' into the SOP and optimize the liner to distribute the load; many 'mold deformation' complaints are actually caused by the packaging and logistics links.

Q

PP Part Low-temperature Drop Fracture

A

For PP low-temperature drop fracture, first modify the structure (fillets, reinforcing ribs, weld line avoidance), then change the grade (impact copolymer); passing at room temperature does not mean passing at low temperature—verification must simulate real use temperature.
