Fluorosint® Synthetic Mica Filled PTFE

MOST DIMENSIONALLY STABLE PTFE-BASED PRODUCT

Chemical resistance parallels PTFE		Compared to PTFE:
Continuous use temperatures to 500°F (260°C)		- higher load carrying capability - 1/9 of the deformation under load - lower coefficient of thermal expansion

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.

Fluorosint® 500 - has nine times greater resistance to deformation under load than unfilled PTFE. Its coefficient of linear thermal expansion approaches the expansion rate of aluminum, and is 1⁄5 that of PTFE - often eliminating fit and clearance problems. Fluorosint® 500 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 - has unmatched dimensional stability, excellent creep resistance and white color uniquely position this material to serve FDA regulated applications. Fluorosint® 207 is non-permeable in steam and complies with the FDA's regulation 21 CFR 175.300. Its relative wear rate is 1⁄20 the rate of PTFE below 300°F (150°C) making it an excellent choice for aggressive service bearings and bushings.

Proven applications include:

Labyrinth seals and shrouds for turbomachining
Dishwasher arm bearing
Transmission and power steering seal rings for automobiles
Valve seats

ENGINEERING NOTES

Due to its PTFE matrix, Fluorosint®'s physical strength characteristics are not as high as other advanced engineering plastics profiled in this guide (i.e., Ketron® PEEK, Torlon® PAI).
