Compressed fiber gaskets Planiflex™ PF65

Composition

Inorganic synthetic fiber and glass, inert filler and NBR binder

Characteristics

The compressed fiber gasketing sheets Planiflex™ PF65 are a material with an excellent parameter of relaxation stress and perfect for steam applications. Suitable with oils, gas, fuels and weak inorganic acids.

Applications

Planiflex™ PF65 can be applied in the temperature range -40°C÷330°C and in the pressure ranges up to ratings 300 lbs and PN25 for RF flanges. These gaskets show chemical compatibility in the pH range typical of that of nitrile rubbers.
