PPSU flame retardant performance
Problem Phenomenon
PPSU inherent flame retardancy UL94 V-0, but product defects affect performance.
Cause Analysis
PPSU inherent flame retardancy needs no additives; V-0 grade; product bubbles and impurities affect; thickness affects; test standards.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Product internal quality assurance; ②thickness according to standards; ③flame retardant test; ④grade selection.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPSU inherent flame retardancy is a safety advantage; product quality determines performance; test verifies grade.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
