When comparing PE (Poliéster) vs. PVDF (Fluoruro de polivinilideno) láminas de aluminio recubiertas, la “mejor” option depends on your specific needs for durability, ambiente, presupuesto, y estética.
PE vs PVDF Coated Aluminum Sheets
educación física (Poliéster) Hojas de aluminio revestidas
Tipo: A standard, widely used thermosetting polymer coating.
Durability/Lifespan: Moderate. Typically offers a shorter service life compared to PVDF, especially in harsh environments.
Weather Resistance (Uva, Rain, Temperatura): Good, but susceptible to degradation over time from prolonged UV exposure. Can fade and chalk (develop a powdery surface) more quickly than PVDF, particularly with darker colors in sunny climates.
Color Retention: Fair to Good. Colors can fade noticeably over 5-10 años, depending on the environment and color intensity.
Chalking Resistance: Fair. More prone to chalking than PVDF.
Gloss Retention: Fair to Good. Gloss level can diminish over time due to weathering.
Resistencia química: Moderate.
Flexibility/Formability: Generally good, allowing for bending and shaping without cracking the coating (within limits).
Hardness/Scratch Resistance: Moderate.
Costo: Lower. Esta es su principal ventaja. Significantly cheaper than PVDF.
Typical Warranty: Often in the range of 5-15 años (highly variable by manufacturer and specific product).
Aplicaciones típicas:
Interior decoration (ceilings, wall panels)
Señalización
Short-to-medium term exterior applications
Areas with moderate weather conditions
Budget-sensitive projects
Rain gutters, downpipes (where aesthetics might be less critical long-term)
PVDF Coated Aluminum Sheets
Tipo: A premium, high-performance fluoropolymer coating. Often uses resins like Kynar 500® or Hylar 5000® (typically requiring a minimum of 70% PVDF resin for optimal performance).
