DESCRIPTION

click to resize photo Fluorosint ® is a proprietary mixture in which synthetically manufactured mica is chemically linked to PolyTetraFluoroEthylene (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. Fluorosint ® is produced only by Quadrant DSM Engineering Plastic Products.

Fluorosint ® offers excellent chemical resistance and continuous use temperature of 500°F (260 °C). Compared with PTFE, it has higher load carrying capability, 1/9 of the deformation under load, and a lower coefficient of thermal expansion.

Quadrant developed the Fluorosint range of enhanced PTFE materials to fill the performance gaps where unfilled and low-tech filled PTFE based polymers typically underperform. Each Fluorosint material has been developed to excel in specific bearing and seal applications. While each of these materials possess the chemical resistance and compliance of PTFE, each material offers some special benefits that give the designer clear performance advantages.


FLUOROSINT GRADES

FLUOROSINT ® 500     Datasheet
Exceptional Dimensional Stability for Precise Tolerance Control

Fluorosint ® 500 has nine times greater resistance to deformation under load than unfilled PTFE. Its coefficient of linear thermal expansion (CLTE) approaches the expansion rate of aluminum and is 1/5 that of PTFE -- often eliminating fit and clearance problems. It is 1/3 harder than PTFE, has better wear characteristics, and maintains low frictional properties. Fluorosint ® 500 is also non-abrasive to most mating materials.

FLUOROSINT ® 207     Datasheet
Lowest Coefficient of Friction of Fluorosint Grades

Fluorosint ® 207's unmatched dimensional stability, excellent creep resistance and white color uniquely position this material to serve FDA regulated applications. It is non-permeable in steam and complies with FDA regulation 21 CFR 175.300. It's relative wear rate is 1/20 the rate of PTFE below 300°F (150°C).

FLUOROSINT ® HPV     Datasheet
Most Wear-Resistant Fluorosint Grade

Mica-filled PTFE provides a unique blend of strength and dimensional stability along with an excellent wear enhancing additive technology. This product provides excellent wear and stability in addition to FDA compliance.

FLUOROSINT ® MT-01     Datasheet
Ultra-High Performance Grade For Stability At Elevated Temperature

Fluorosint ® MT-01 is an extreme service grade developed specifically for applications where the benefits of PTFE-based materials also require strength, stiffness and stability. Fluorosint MT-01 delivers high mechanical performance at elevated temperature and as a result is often specified in seat, seal, and wear applications where extreme conditions are present.
