PEI Aviation Interior Part Flame Retardancy
Sorun Belirtisi
PEI aviation interior parts have batch fluctuations in flame retardancy tests; although naturally flame retardant, product quality affects performance.
Neden Analizi
PEI has excellent natural flame retardancy, with an oxygen index of 47% and UL94 V-0 without adding flame retardants; but internal product defects such as bubbles affect flame retardant performance; thin-wall and thick-wall differences; processing degradation reduces performance.
Çözüm
①Non-destructive testing of product internal quality; ②control processing heat history; ③uniform wall thickness design; ④batch verification of flame retardant performance.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
PEI's natural flame retardancy is a material advantage; product quality determines the realization of the advantage; batch verification ensures aviation safety.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
