PESU Flame Retardant Performance
Problem Phenomenon
PESU is inherently flame retardant UL94 V-0, but product defects affect performance.
Cause Analysis
PESU is inherently flame retardant without additives; V-0 rating at 1.5mm or 0.8mm glass fiber reinforced; product bubbles and impurities influence; thickness influence; test standards.
Solution
①Product internal quality assurance; ②thickness according to standards; ③flame retardancy testing; ④grade selection.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PESU's inherent flame retardancy is a safety advantage; product quality determines performance; testing verifies the rating.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
