WR 650 from Greene Tweed

Greene Tweed, based in Kulpsville, PA, has announced the introduction of WR 650, the latest thermoplastic composite in its wear-resistant portfolio.

WR 650 is reinforced with a 3D carbon-fibre architecture, offering enhanced performance over the leading PFA-based material, while maximising equipment reliability.

It is said to offer superior dry run capability, excellent chemical resistance, and an operating temperature up to 260°C (500°F). Its higher fibre content provides a harder material over a wide range of operating temperatures.

The significant competitive advantages of WR 650, include:

A 2.5 times higher PV limit in dry run conditions over the leading PFA-based material.

It remains effective during testing conditions, particularly during dry runs, increasing the time between repairs.

A coefficient of thermal expansion four times lower in the axial direction than the leading PFA-based material.

A single, reliable material that covers both high temperature and corrosion.

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 request.
