WR® 650 is reinforced with a three-dimensional carbon-fiber
architecture, offering enhanced performance over the leading PFA-based
material, while maximizing equipment reliability.

WR® 650 offers superior dry run capability, excellent
chemical resistance, and an operating temperature up to 260°C (500°F).
Its higher fiber content provides a harder material over a wide range of
operating temperatures.

WR® 650 offers significant competitive advantages, including:

  • 2.5 times higher PV limit in dry run conditions over the leading
    PFA-based material
  • Maintains production during upset conditions, particularly during dry
    runs, increasing MTBR (mean time between repair)
  • A CTE (coefficient of thermal expansion) four times lower in the axial
    direction than the leading PFA-based material
  • A single, reliable material that covers all applications – high
    temperature, corrosion
  • Rapid product delivery ensures material availability during pump

Many of the world's leading refineries, chemical plants, power
generation plants, pipelines, and water treatment plants choose Greene
Tweed's composites for their ability to withstand the most challenging
applications in the harshest environments. Available in a broad
range of stock shapes, WR® 650 customers are able to machine
parts to their exact specifications. Finished parts are available upon
