PESU Aircraft Interior Low-Smoke Application
Problem Phenomenon
【Problem Phenomenon】Aircraft interior parts have stringent flame-retardant and low-smoke requirements, and conventional materials fail smoke density standards
Cause Analysis
PESU is inherently flame retardant with low smoke release, UL94 V-0 without flame retardants, low smoke and low toxicity when burning; meets aviation interior flame retardancy requirements and can be used in electronics and aerospace
Solution
Choose PESU inherently flame-retardant grades for aviation interior parts; verify according to aviation smoke density standards; the flame-retardant-free characteristic avoids precipitation risk; after adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PESU is flame-retardant-free V-0 low smoke, the chosen material for aviation interiors; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
