What are the building membrane materials

Classification by Material

Polyester Film (PET)
Characteristics: High strength, tear resistance, chemical corrosion resistance, adjustable light transmission (from transparent to translucent), and surface coating compatibility.
Applications: Commonly used in architectural window films (e.g., heat insulation films, explosion-proof films), sunshade substrate materials, and decorative films.

Polyvinyl Chloride Film (PVC)
Characteristics: Excellent flexibility, strong weather resistance, adjustable hardness via plasticizers, and printable surfaces.
Applications: Widely used in tensile membrane structures (e.g., stadium roofs), advertising lightboxes, and temporary architectural sunshades.

Polytetrafluoroethylene Film (PTFE, Teflon)
Characteristics: High temperature resistance, corrosion resistance, self-cleaning properties, high light transmission (up to 85% or higher), and a lifespan exceeding 25 years.
Applications: High-end architectural membrane structures (e.g., airport terminals, large stadium roofs) and skylight systems.

Ethylene Tetrafluoroethylene Copolymer Film (ETFE)
Characteristics: Lightweight and transparent (only 1% the density of glass), UV resistance, self-cleaning properties, and recyclability.
Applications: Large-scale public buildings (e.g., the "Water Cube" National Aquatics Center), greenhouses, and landscape canopies.
