Teflon Roof Structure

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 roof structure.

Polytetrafluoroethylene ptfe a strong tough waxy nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. 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. Few solid substances adhere permanently to a teflon industrial coating. To ensure construction safety a construction monitoring scheme was.

This tensile fabric roof material has a life span of over 25 years and is manufactured in. The well known brand name of ptfe based formulas is teflon by chemours. The woven fiberglass gives ptfe coated glass fiber its mechanical strength and providing the membrane with maximum flexibility. A range of ptfe material types is available that include ptfe coated glass fiber ptfe glass mesh and silicone coated glass fiber.

A short history of the use of teflon fabric in the construction industry is available on nasa s technology transfer program s website. As a result the low surface adhesion properties in the ptfe structures easily cleaned by rainwater and immune to uv radiation. Ptfe or polytetrafluoroethylene is a teflon coated woven fiberglass membrane that is extremely durable and tolerant of even the most extreme weather elements. Teflon industrial coatings are desirable for use across many applications based on the following properties.

This makes it ideal for large scale roof and tensile membrane structures. Tacky materials may stick temporarily but almost all substances release easily. Ptfe has been in commercial use since the 1940s. 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.

Teflon is a brand name used for a group of man made chemicals the most common of which is polytetrafluoroethylene ptfe. What are teflon and pfoa. Ptfe coating is chemically inert and capable of withstanding a wide range of temperatures and any climate. 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.

Where are they found. Building codes and roofs. 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. The roof steel structure in the terminal 2 building of yancheng nanyang airport has a large span and a considerably difficult construction.

Chemours was a spin off from dupont which originally discovered the compound in 1938. Polytetrafluoroethylene ptfe is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications.
