Note: PTFE is the generic chemical name for what is commonly referred to as Teflon庐.
The term Teflon庐 refers to a PTFE manufactured only by DuPont.
Fluorogold庐 is a glass fiber reinforced PTFE or Teflon庐 that provides added strength and durability to withstand higher loads and more demanding environments.
Teflon庐 Slide Bearings
The most common Teflon庐 application in Structural 亚博系列全平台入口 fabricating is the Slide Bearing. Shown to the right, it has an upper and lower element and allows for expansion and contraction of steel members due to changes in temperature, wind shear, seismic activity, etc. Slide Bearings can be manufactured to any dimensions. If necessary the Slide Bearing can be formed on a radius for use in Pipelines and Ducts.
Teflon庐 Thermal Breaks
A secondary benefit Teflon庐 provides is its ability to restrict energy transfer. In short, when heat (energy) attempts to transfer through any steel connection a Teflon庐 bearing pad will block the transfer. This creates an energy savings over the life of the building.
Washers, Separators and Bearings
Teflon庐 is also used as a Washer or Separator between rotating members. This can be something as small as 1鈥� O.D. gate hinge or any larger size up to 24鈥� O.D. as a single piece, or sectional for any size larger as shown below.
One recent project required Teflon庐 Washers 5鈥� O.D. x 4-1/16鈥� I.D. x 1/8鈥� thick. (left) The design was for large, heavy panels that would pivot on a 4鈥� O.D. round tube. The panel flange would rest on a collar that was welded to the tube. (right)
For sizes larger than 24鈥� The 亚博系列全平台入口 Supply Company would produce the desired item in sections. The crescent shaped sections are then pieced together and bonded to a steel backing plate. This is done to accommodate the size of the PTFE sheets and also to limit the drop.
Using evenly distributed pressure and prolonged, consistent heat a very strong bond can be achieved that will withstand significant pressure, torsion and harsh environments.
