Latest additions can outperform competing PTFE materials up to 40 percent on bearing performance measures; present new material options to engineers for demanding oil and gas applications.

Quadrant’s range of enhanced PTFE materials available in full production sizes has been broadened with the addition of two new grades: Fluorosint HPV and Fluorosint MT-01. Fluorosint HPV, especially developed for highly demanding oil & gas applications, is a mica-filled high performance bearing grade that can deliver a pressure velocity (PV) performance improvement of more than 40 % over other PTFE materials according to in-house tests conducted by Quadrant.

Parts made of Fluorosint HPV can withstand higher load and velocity while delivering better wear resistance, enabling longer part life compared to existing PTFE-based materials. The product was especially developed to meet the demands of high performance bearing applications where other, low-tech PTFE formulations would exhibit premature wear or can not perform. These characteristics open up interesting new options for engineers and manufacturers.

Dr. Stephan Glander, Global Director Research & Market Development Quadrant EPP comments: “Simply put, parts machined from Fluorosint HPV last longer than those made from many of the alternative filled PTFE materials on the market today. Fluorosint HPV can replace bronze, steel and powdered metal parts and deliver performance gains in wear life and system performance. Typical applications include thrust washers, wear guides, valve bushings and seals.”

The second new grade addition, Fluorosint MT-01, is a unique material that combines exceptionally high temperature resistance with low deformation and low CLTE (Coefficient of Linear Thermal Expansion). “Engineers often need to balance compliance of PTFE, its ability to both deform and retain rigidity, with precise control, even at elevated temperatures. Fluorosint MT-01 is perfectly suited to perform under these conditions,” Dr. Glander adds.

Fluorosint MT-01 was developed for high temperature applications such as bearings, seals and wear surfaces where higher loads are present. Equipment exposed to elevated temperatures such as ovens, dryers and linear positioning equipment are all ideal applications for this ultra-performance grade.

Quadrant offers these materials in a wide range of rods, sheets and tubular shapes for machining. Design and manufacturing of finished parts is also available.

The Fluorosint range of enhanced PTFE materials, initially introduced in 2007, was specifically developed by Quadrant to meet the performance requirements that unfilled and low-tech, filled PTFE based polymers can not provide for high performance bearing applications. Fluorosint's unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to PTFE. This bonding results in properties not normally attainable in reinforced PTFE. Fluorosint grades offer an excellent combination of low frictional properties and dimensional stability.

Each Fluorosint material grade has been developed to excel in specific, highly demanding bearing and seal applications. While each of these materials possesses the chemical resistance and compliance of PTFE, they all offer particular benefits that give designer clear performance advantages.
