PCABS Flame-Retardant Processing
Problem Phenomenon
The processing temperature of PC/ABS flame-retardant materials is reduced to protect sensitive flame retardants.
Cause Analysis
The processing temperature of PC/ABS flame-retardant materials is usually reduced to 230-260°C; sensitive flame retardants thermally degrade; viscosity modifiers improve flow; lubricants reduce shear; stabilizers protect; drying at 90-110°C for 2-4 hours.
Solution
①Processing temperature 230-260°C; ②viscosity modifier; ③lubricant; ④stabilizer; ⑤drying at 90-110°C×2-4h.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
The low temperature and additives in PCABS flame-retardant processing are protection strategies; the drying standard remains unchanged; balance ensures performance and processing.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
