PCTFE (polychlorotrifluoroethylene), commonly referred to as Kel-F® or Neoflon®, is a fluoropolymer material with outstanding strength, stiffness, and dimensional stability.

LNG – Liquefied Natural Gas – is a mixture of hydrocarbons composed mainly of methane, but with varying levels of ethane, propane, butane and other gases present in natural gas. In general, LNG has a boiling temperature between -166°C and -57°C at atmospheric pressure.

 The PCTFE Seals or PCTFE seat is widely used in LNG or cryogenic applications. PCTFE's stability at low temperature makes it an ideal choice as a ball valve seat or butterfly valve seat material. 

We can design and manufacture PCTFEseals as per drawing or sample
