Teflon is commonly know as PTFE, it is a kind of plastic with extremely high corrosion resistance ability. Bellows expansion joints which made from PTFE or Teflon are usually known as PTFE bellows expansion joint or Teflon bellows expansion joint. Lanphan PTFE bellows expansion joint has the same product structure with metal expansion joints, the only difference is material. Metal expansion joints always use stainless steel or carbon steel to manufacture, while PTFE bellows expansion joint is made from Teflon.

You can find the PTFE bellows expansion joints in industries of chemical engineering, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and space navigation. Teflon bellows expansion joint has following characteristics:

Light weight, good flexibility: Teflon is light in weight, so the teflon bellows expansion joint is much lighter than metal expansion joint, which is convenient to install and operate.

Resistant to high and low temperature, high pressure and corrosion: teflon expansion joint has the capacity to bear high temperature of 250íŠ under pressure of 3kg/cm2, and meanwhile skin temperature not exceed 60íŠ, which ensured operation safety. Even if the temperature dropped to -196 íŠ, it can also maintain the elongation of 5%.

Non-toxic: it has a physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.

Weather-proof: service life is the longest among plastic.

Inadhesion: The smallest surface tension in solid material, don't adhere to any material, the lowest friction coefficient in solid materials.

High lubrication: the lowest friction coefficient in solid materials.
