PTFE, an acronym for polytetrafluoroethylene, is a braided and coated glass fiber membrane with great mechanical strength.
The diameter of the glass fiber that forms the substrate of the fabric of the PTFE membrane material is between 3.30 and 4.05 μm and its weight is greater than 150 g/m.
A wide range of PTFE material types are available, including PTFE-coated glass fiber of different thickness and strength and PTFE glass fiber mesh.
The main characteristic of PTFE is its ability to be extremely durable and tolerant to even the most extreme weather conditions: PTFE fiberglass membranes can be installed in climates ranging from Arctic cold to scorching desert heat with a very long life expectancy.
Properties of PTFE
- Resistance: PTFE-coated covers are chemically inert and capable of withstanding temperatures from -80°C to +260°C
- Lightness: its weight can be defined as a small fraction of traditional building materials
- Strength: the average thickness of a PTFE membrane is only 0.8 mm, but its tensile strength is equal to that of steel
- Modelability: its elastic modulus is low, favoring the possibility of modeling complex curved surfaces
- Weldability: each PTFE membrane can be welded to another, up to form large surfaces
- Self-cleaning: the low surface of the material is cleaned by rainwater
- Shading: the light transmission of PTFE membranes is very high, but without the passage of UV rays, preventing fading of materials and decorations
- Reduced consumption: by using PTFE-coated glass fibers energy savings can be realized, and in addition, the high reflection performance ensures excellent lighting effect even in the dark, reducing consumption.
Use of PTFE membranes
PTFE architectural membranes are widely used for the construction of roofing systems for stadiums, swimming pools and sports fields, tensile structures, airport pavilions, exhibition centres, platforms, facades, canopies, roofs.
Canobbio Textile has made numerous PTFE designs for different types of covers, including the tensile structure of the velodrome Abuja Nigeria, consisting of 36 panels in PTFE highly durable trapezoidal shape, for a capacity of 6,000 spectators, and the marquee at the archaeological area of Caposoprano in Gela, protecting the famous Thymoleon walls, ancient Greek fortifications that constitute a very important archaeological record of the defensive system that surrounded the hill on which the ancient city stood.
