Q

ASA Vicat softening 101°C

A

ASA 101°C Vicat is a heat resistance reference; boundary management ensures application; grade matches demand.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

ASA continuous temperature resistance exceeded

A

The temperature resistance boundary of ASA is at a medium level, and high-temperature applications require margin evaluation; creep is the invisible killer of long-term thermal load; measured working condition temperature is more reliable than theoretical values.

Q

ASA solvent resistance cracking

A

The chemical resistance boundary of ASA must be confirmed at the material selection stage; environmental stress cracking is the product of stress and medium; cleaning agent compliance is often overlooked on site.; After confirming effectiveness, solidify the parameters and practices into the work...

Q

ASA excessive back pressure shear degradation

A

The back pressure principle of ASA is: as low as sufficient; high shear tolerance does not mean unlimited; rubber phase integrity is most directly verified by impact strength.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

ABS environmental protection and sustainability

A

ABS environmental protection relies on recycling and compliance, bio-based is on the way; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar...

Production & Quality environmental protection RoHS bio-based sustainability

Q

ABS glass fiber reinforced processing

A

ABS glass fiber reinforcement is a trade-off between performance and appearance; floating fiber and surface are challenges; balance ensures application value.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Production & Quality ABS; glass fiber reinforcement; strength; transparency; toughness; floating fiber

Q

Narrow processing window of high heat resistant ABS

A

Special ABS must follow the grade's dedicated process: applying the general process to heat-resistant material results in either yellowing or brittleness; for narrow-window materials, temperature control precision and residence time must be managed even more strictly.

Q

ABS stress cracking (solvent induced)

A

ABS 'stress + solvent = cracking': reducing internal stress and avoiding solvents both work together; residual stress is a time bomb, the solvent is just the fuse, and high-stress parts must have the stress reduced from the process.

Q

ABAK automotive component application

A

ABAK automotive application is the main market; comprehensive performance matching is the value; verification ensures mass production quality.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Production & Quality ABAK；automotive；bumper；instrument panel；matte；verification

Q

Excessive porosity of sintered products

A

This problem needs to be comprehensively analyzed from multiple dimensions of material, process, equipment, and operation, and solved by systematically optimizing process parameters and the quality control system.
