PBT outdoor weathering application
Problem Phenomenon
Performance decay of outdoor products.
Cause Analysis
PBT weather resistance is good but long-term ultraviolet exposure still requires a stabilization system; ordinary grades have limited outdoor life.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Select UV-stabilized grades for outdoor use; ②add light stabilizer; ③conduct aging tests; ④verify according to life requirements.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBT weather resistance is its advantage but requires a supporting stabilization system.; 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
