Perlast® G75B

Perlast® G75B is a black, high temperature, perfluoroelastomer compound. It provides a unique combination of excellent chemical resistance, mechanical properties and high temperature stability.

Perlast® G75B exhibits low permeability and is less prone to swelling, leading to extended in-service performance in valves, pumps, and mechanical seals.

A high modulus makes Perlast® G75B resistant to extrusion, making it ideal for use in medium-high pressure applications. In addition, the low cumulative compression set results in longer periods between maintenance cycles in hot chemically aggressive environments.

Perlast® G75B is suitable for both dynamic and static applications and can be moulded into O-rings (any size up to 2m/6.5ft diameter) and custom shapes.

 

Key attributes:

  • High temperature performance up to +325°C (+617°F).
  • Outstanding physical properties.
  • Excellent chemical resistance.
  • Good steam resistance (ASME BPE 2000) .
  • Long-term sealing effeciency at high temperature .
  • Low permeability ideal for vacuum applications.
  • Low swell in Jet Oil.
