What's PTFE membrane?
PTFE Architecture Membrane is made by coating a non-chemically reactive PTFE resin on an ultrafine glass fiber cloth. PTFE Membrane structure is a brand-new form of building structure.
Features of PTFE Coated Architecture Membrane
- Super Anti-UV characters: For outdoor application, it would last 25-35 years without damage
- High strength, the tensile strength of PTFE membrane reaches the level of steel; and the lower modulus of elasticity is beneficial to the complex surface shape of the membrane
- Unique optical properties, and the incident light becomes natural warm light during the day, preventing glare, no shadow, and even light distribution; almost no ultraviolet light is transmitted, preventing the fading of interior decoration materials and equipment; night high reflection performance makes the room It has excellent lighting effect, reduces power consumption, and can bring out the brilliance of buildings in the night sky
- Self-cleaning, rainwater can wash away the attachments on the surface
- Having high light transmittance, a light transmittance of 13%, a thermal energy reflectance of 73%, and a small heat absorption amount
- Stable sizes: With fiberglass fabric, it never shrinks or elongation.
