Q

PP Melt Temperature 200-280

A

PP melt temperature 200-280°C is the standard range; the 300°C red line is the safety boundary; actual measurement prevents display errors.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PP; melt temperature; 200-280°C; 300°C; grade; actual measurement

Q

PPS Wear-Resistant Grades

A

PPS wear resistance is achieved through modification; PTFE and carbon fiber are two mature low-friction routes; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PPS; wear resistance; PTFE; carbon fiber; PV value

Q

PPS Inherent Flame Retardancy Advantage

A

Inherent flame retardancy is PPS's core competitiveness; being flame-retardant-free means purer performance and less precipitation; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PPS; flame retardant; UL94 V-0; self-extinguishing; low smoke

Q

PPS Full Regrind Feasibility

A

PPS's regrind tolerance stands out among engineering plastics; the 85% retention rate gives large reuse room for internal parts; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PPS; full regrind; 85%; thermal stability; recycling

Q

PPS Regrind Usage Ratio

A

PPS regrind management has clear ratio discipline; the 25-30% upper limit plus drying verification, stricter for UL parts; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PPS; regrind; 25-30%; UL; drying

Q

PPS brittleness and toughening

A

Brittleness is the first shortcoming of pure PPS; toughening modification is the necessary path for application expansion, PPA system is the mainstream route; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PPS; brittleness; toughening; PPA; impact

Q

PPO Material Modification Directions

A

PPO has a rich modification menu, and selecting the direction according to the shortcoming is the key; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting ...
