LDPE Anti-UV Modification
Problem Phenomenon
Outdoor LDPE products age quickly
Cause Analysis
LDPE has poor weather resistance and ages rapidly outdoors; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
Select carbon black or anti-UV grades; manage outdoor applications by service life; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate the effective measure
Key Takeaway
Outdoor LDPE must be anti-UV modified; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
