ASA Flame Retardant Grade Application
Problem Phenomenon
【Problem Phenomenon】Outdoor electrical parts require both flame retardancy and weather resistance, material difficult to choose
Cause Analysis
ASA has UL94 V-0/V-2 flame retardant grades and maintains weather resistance; outdoor charging piles, photovoltaic junction boxes and other scenarios need dual performance; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solution
Choose ASA flame retardant grades for dual needs of flame retardancy and weather resistance; UL yellow card checks rating and thickness; re-test flame retardancy after outdoor aging; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA flame retardant grades bear both weather resistance and flame retardancy, yellow card checks the rating; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
