Fluoropolymer slide bearing material
TOMBO™ No. 9017
NAFLON™ SLIDING PAD
Various slide bearing pads (sliding pads) are used to absorb the expansion and contraction that occurs in structures such as bridges or corridors between buildings.
NAFLON™ Sliding Pad, which uses filler-filled fluororesin (PTFE), is superior to conventional rubber pads, metal plates, roller bearings, etc. in many aspects such as low friction, high weather resistance and chemical resistance.
PTFE has the lowest friction coefficient of any solid. In addition, slipping is smooth without the stick-slipping caused by metal, thanks to its excellent static and dynamic friction behavior.
PTFE is self-lubricating and requires neither refueling nor maintenance.
Excellent weather resistance
PTFE, which has excellent weather resistance, can cope with a wide range of temperature and humidity. In particular, as it does not absorb water, it can also maintain its stable performance for long periods without being affected by anything even under conditions where freezing may occur.
Excellent chemical resistance
PTFE can be used without being affected by anything even in an atmosphere that corrodes metals and can also be used in chemical plants or areas close to the sea without any problems.
Note, however, that it reacts with the following substances:
Alkali metals (e.g. sodium, potassium, lithium) Extremely strong oxidants
(e.g. fluorine gas (F2) at high temperatures)
Special compounds that emit active fluorine gas at high temperatures (chlorine trifluoride, bromine trifluoride, iodine pentafluoride, OF2)
