The core characteristics of PTFE membrane materials

Exceptional Durability:

Designed service life ≥ 25 years; many early PTFE buildings have been in good condition for over 40 years.

UV Resistance: Completely immune to UV degradation.

High and Low Temperature Resistance: Adaptable to extreme temperature ranges from -70℃ to +250℃.

Chemical Corrosion Resistance: Resistant to virtually all strong acids, strong alkalis, and organic solvents.

Ultimate Fire Safety:

Material grade A non-combustible (Chinese standard). Both the base fabric (glass fiber) and coating (PTFE) are non-combustible. When exposed to fire, they only melt and shrink, without dripping or producing toxic fumes, making it a membrane material with very high life safety performance.

Superior Self-Cleaning Properties:

After an initial "self-cleaning period," the surface is extremely smooth, hydrophobic, and oleophobic. Dust and contaminants cannot adhere, and rainwater can clean it, reducing maintenance and cleaning costs.

Excellent Optical and Thermal Properties:

Light Transmittance: Approximately 10%-20% natural light transmittance, creating soft, uniform diffused light without glare, eliminating shadows, making it ideal for sports stadium lighting.

Heat Reflectivity: High reflectivity and low absorption of solar heat radiation (infrared rays), providing excellent thermal insulation and keeping building interiors cooler.

High Strength and Stability:

Extremely high strength-to-weight ratio, high tensile strength, and minimal creep relaxation. This means minimal prestress loss after tensioning, maintaining shape stability for decades.
