Expanded PTFE gaskets are designed for use in chemical, pulp and paper, food and beverage, and other general industrial applications where process piping and equipment are required to be resistant to highly aggressive chemicals.

The expanded PTFE gasket material is suitable for irregular surfaces of steel flanges and flanges.

The expanded PTFE gasket material is made of pure PTFE resin only. It applies to steel flanges and flanges that require highly compressible gaskets. Also applies to the irregular surface of the sealing flange. There will be no cold flow problems associated with the original PTFE or some other filler PTFE product hardness problems. It has excellent sealing, easy to cut, and after use with the flange clean separation.

When the temperature and pressure are listed in the maximum value, never recommend the use of expanded PTFE gasket. The properties and applications shown are typical. Person who does not have an independent study and assesses suitability shall not make any application. Do not use multiple washers in a flange fitting, do not reuse the gasket. Improper use or gasket selection may result in property damage and / or serious personal injury.

This is a sealant made of 100% pure expanded PTFE. It is usually produced in the form of tape and is not suitable for cord, plate and other forms. Expanded PTFE includes all the special operating parameters of PTFE and additional features obtained during the expansion process. Due to its excellent flexibility and ductility, it is very easy to maintain the shape of the sealing surface, and the tape can make the fitting fast. In addition to the flange seal, it can be used in other static sealed cases, as long as the operating parameters to reach the range of PTFE value.
