PTFE filled with 5% to 10% mica 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® is a proprietary mixture 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, dimensional stability, 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.
FLUOROSINT GRADES
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’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). The combination of good mechanical performance and its inherent outstanding chemical and hydrolysis resistance, Fluorosint® 207 opens numerous application possibilities in food, pharmaceutical, and medical industries.
