PLANIFLON PT2105

Composition

Middle rings and Top & Bottom rings: Modified PTFE

Characteristics

Key characteristics of the Planiflon PT2105 include a specific gravity of 2.15 g/cm3, tensile strength of at least 28 N/mm2, and elongation at break of at least 350%. The tensile modulus is at least 600 N/mm2. Shrinkage is 3%, while deformation under load is 15%. The material is classified as V-0 for flammability and has a dielectric strength of 2.5 kV/mil. The service temperature range (general service) is from -200°C to 260°C. It is BAM approved for oxygen service.

Applications

The Planiflon PT2105 is a Chevron-configured seals particularly suitable for applications requiring reliable sealing of stems and seats of industrial valves in sectors such as chemical, petroleum, and pharmaceutical. Suitable for high-pressure and extreme temperature applications.
