PTFE seals are designed for dynamic, high pressure and high temperature environments where a rubber seal or gasket would fail. Polytetrafluoroethylene (PTFE) maintains a low coefficient of friction and a high chemical resistance for the most aggressive applications.
TLBP-01: PTFE bearing pads feature small friction coefficient. PTFE bearing pad , also called Teflon bearing pads, is an important material in bridge construction. The dimpled PTFE sheet bonded to the laminated bearing pad for structure friction coefficient reduction and displacement capacity improvement.

the lowest effective coefficient of friction of the four rolling devices tested. For turned pipe rollers it was found that the equivalent coefficient of friction is a function of the amount of horizontal movement from the centerline. A geomet­ ric explanation was devised, and excellent agreement between predicted and measured results was achieved.
Low coefficient of friction between pipe and resilient coated pipe roller. How to size: If the roll is to support bare pipe, select the size directly from nominal pipe size. If used with pipe covering protection saddle, see Figs. 160 – 166A submittals for size of pipe roll. Ordering: Specify pipe roll size, figure number, name and finish. Be ...

Internally lubricated Nitrile (reduced friction) FDA compounds (Food and Drug applications) NSF compounds (Food and potable water applications) Fluorocarbon. Probably best known by the trade name Viton®, fluorocarbon or fluoroelastomer compounds exhibit excellent chemical resistance to chemicals, oils, and extreme temperatures (-15° to +400° F).
Teflon silicone laminate used in applications where cushioning and very low coefficient of surface friction are desired such as dynamic sealing applications. Thermally conductive silicones are used in applications where the transfer of heat away from a structure and sealing are required from the same material.

Neoprene Coated Fig. 200 U-Type Upthrust Constant Spring Supports. A total of 40 constant and variable spring supports were fabricated as replacements. Each support was sealed with a neoprene coating over a hot-dip galvanized finish instead of stainless steel. This type of finish will ensure a much longer life-span.
FluoroKote#1® possesses a low coefficient of friction which reduces torque requirements. When FluoroKote#1® coated fasteners are used, galling and seizing become problems of the past. Due to the absence of nut locking oxides after extensive exposure to corrosive environments, fasteners coated with our process do not need to be removed by ...
