The application scenarios of PTFE and PVC tensioned membranes are distinguished

PTFE Tensioned Membrane System Applications

1. Mega-Scale Sports Complexes
Implementation Case: Beijing Olympic "Bird's Nest" National Stadium

• Structural Advantage: Utilizes PTFE's ultralong span capacity (>250m unsupported)
• Material Performance: 0.3-1.2mm membrane thickness with 90%+ UV resistance (per ASTM G154)
• Engineering Benefit: Enables column-free roofing (120,000㎡ coverage) maintaining 25% light transmission

2. Permanent Exhibition Architectures
Representative Project: Shanghai World Expo Pavilions

• Optical Efficiency: 12-18% visible light transmission with 92 CRI color rendering
• Maintenance Advantage: TiO₂-coated surface achieves Class A self-cleaning (ISO 27447)
• Durability: 30+ year service life with ≤0.5% annual tensile strength loss

3. Premium Commercial Structures
Typical Installations:

• Airport Terminals: Seamless spans up to 150m (FAA wind load compliant)
• Luxury Retail Complexes: 500-800g/㎡ fabric weight options
• Performance Metric: 1.5kN/m tear strength (EN ISO 1421)

4. Cultural Facilities Enhancement
Lighting Performance:

• Diffuse illumination: 200-500 lux uniformity (CIE 117:1995)
• Thermal Regulation: U-value 0.8W/m²·K (EN 673)

PVC Tensioned Membrane System Applications

1. Community Sports Facilities
Cost-Effective Solution:

• Budget Compliance: $80-120/㎡ installed cost
• Rapid Deployment: 3-5 day installation cycle for 1,000㎡ projects

2. Temporary Event Infrastructure
Operational Advantage:

• Modular Design: 15m×30m standard bay configuration
• Mobility Feature: Complete dismantling <8 hours

3. Landscape Architecture Elements
Aesthetic Flexibility:

• Color Options: RAL/Toyo 200+ chromatic choices
• Formability: 6-8m minimum curvature radius

4. Agricultural Applications
Agro-Technical Specifications:

• PAR Transmission: 55-70% (400-700nm spectrum)
• Thermal Retention: 4-6°C temperature differential maintenance
• Chemical Resistance: pH 3-11 tolerance (DIN 53378)
