A: The fundamental reasons lie in chemical composition and durability. PE is a thermoplastic prone to aging, chalking, and fading under UV, moisture, and pollution. PVDF (Polyvinylidene Fluoride) is a super-stable fluorocarbon polymer with extremely strong molecular bonds, offering unmatched UV resistance, chemical corrosion resistance, anti-pollution, and self-cleaning properties. It ensures the facade’s color and physical integrity remain stable for 15-25 years even in harsh climates.
