PMMA Weathering Application
Sorun Belirtisi
Material selection for outdoor transparent parts is a dilemma; PC parts yellow after two years while PMMA parts remain clear
Neden Analizi
PMMA has excellent weather resistance; outdoors for many years it hardly loses impact strength and appearance, and light transmittance can be guaranteed for 30 years; PC needs a UV layer to compare; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
①Prefer PMMA for outdoor transparent parts; ②choose PC for scenarios with high impact resistance requirements and accept the cost of UV protection; ③include weathering warranty clauses in procurement; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Weather resistance is PMMA's core advantage over PC; PMMA is the default answer for outdoor transparent applications; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
