PE (Polyester) and PVDF (Polyvinylidene Fluoride) aluminum coils are widely used in construction and manufacturing for cladding, roofing, and other applications. Here’s a comparison based on various factors:
PE Coils (Polyester Coating):
Coated with a polyester resin, providing a glossy finish and decent durability.
Economical option.Basic resistance to UV rays, weather, and corrosion.
PVDF Coils (Polyvinylidene Fluoride Coating):
Coated with PVDF, which includes a blend of fluoropolymer resin and other compounds.
Superior weather and UV resistance.
Long-lasting durability in harsh environments.
PE:
Suitable for applications with moderate environmental exposure. Lifespan ranges from 5–10 years, depending on the environment.
PVDF:
Exceptional durability in extreme weather and industrial environments. Lifespan often exceeds 20 years.
PE:
Available in a wide variety of colors and finishes, including glossy, matte, and metallic.
PVDF:
Offers fewer color options than PE but provides a consistently smooth and high-quality finish.
PE:
More affordable due to simpler production processes and lower material costs.
PVDF:
More expensive, reflecting its higher performance and longevity.
PE:
Moderate resistance to UV, heat, and chemical exposure. Better suited for interior or less demanding exterior applications.
PVDF:
Exceptional resistance to UV rays, acids, alkalis, and harsh weather conditions, making it ideal for industrial or marine environments.
PE:
PVDF:
PE:
Requires more frequent cleaning and maintenance to maintain appearance and integrity.
PVDF:
Low maintenance due to its resistance to dirt, fading, and chalking.
