Where are they found.
Teflon roof structure.
Tacky materials may stick temporarily but almost all substances release easily.
As a result the low surface adhesion properties in the ptfe structures easily cleaned by rainwater and immune to uv radiation.
This makes it ideal for large scale roof and tensile membrane structures.
A range of ptfe material types is available that include ptfe coated glass fiber ptfe glass mesh and silicone coated glass fiber.
The roof steel structure in the terminal 2 building of yancheng nanyang airport has a large span and a considerably difficult construction.
Ptfe has been in commercial use since the 1940s.
The structure supports 190 000 sf of polytetraflouroethylene ptfe fabric a teflon coated membrane installed by birdair that is light in weight yet incredibly durable in keeping out the elements especially the sun.
Teflon industrial coatings are desirable for use across many applications based on the following properties.
The article focuses mainly on birdair s contributions to the development of the technology.
Known by such trademarks as teflon fluon hostaflon and polyflon ptfe is distinguished by its slippery surface high melting point and resistance to attack by most chemicals.
This tensile fabric roof material has a life span of over 25 years and is manufactured in.
What are teflon and pfoa.
Ptfe coating is chemically inert and capable of withstanding a wide range of temperatures and any climate.

Few solid substances adhere permanently to a teflon industrial coating.
According to the project characteristics the construction scheme of the roof steel structure follows the principle of subareas and substeps with the truss lifting in segmentation.
Polytetrafluoroethylene ptfe a strong tough waxy nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene.
Polytetrafluoroethylene ptfe is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications.
Building codes and roofs.
Another popular brand name of ptfe is syncolon by synco chemical corporation.
Ptfe is used world wide as the preferred material for large scale permanent tensile structures or structures requiring long life and with specific construction code compliance requirements ptfe has excellent weather temperature and chemical resistance in addition to its durability and strength.
Teflon is a brand name used for a group of man made chemicals the most common of which is polytetrafluoroethylene ptfe.
Ptfe or polytetrafluoroethylene is a teflon coated woven fiberglass membrane that is extremely durable and tolerant of even the most extreme weather elements.
It has a wide variety of uses because it is extremely stable it doesn t react with other chemicals and can provide an almost frictionless surface.
A short history of the use of teflon fabric in the construction industry is available on nasa s technology transfer program s website.
Chemours was a spin off from dupont which originally discovered the compound in 1938.
