PTFE Dispersion Resin F-206
(for paste extrusion)

1.Molecular formula:

[CF2--CF2]n

2.Properties and Applications

In addtion to all excellent properties of PTFE material, F-206, the PTFE suspension resin has outstanding performance in paste extrusion to manufacture sealing tape, etc..The resin are processed by mixing them with some organic solvents, 100# aero kerosene for example, to obtain paste which are made into coherent, smooth and flat semifinished products after ram extrusion.Druing this progression the extruding pressure remains steady.The semifinished products are further processed to produce unsintered tape by calendering, enlongating and removing solvent with heat.
Normally 4 diameters are set for F-206 extruded straps: 5.0mm, 4.5mm, 3.2mm, 2.8mm.

4.Specifications:

Note: The specification above is negotiable to fit customers special requirements.

The PTFE plate is ideal for many machined parts.It can be cut into blocks or strips for fabricating into casings, housings or components for the electrical, chemical processing and various mechanical fabrication industries.PTFE is impervious to virtually all corrosives, its dielectric properties are extraordinarily high, and it has an extremely low coefficient of friction.PTFE will perform in environments from -350 degrees F to over 500 degrees F.Virgin PTFE is FDA approved for use in food processing equipment.
Virtually all processing equipment that conveys parts or assemblies through high heat zones uses PTFE.PTFE costs less than some metals, and will perform better with less maintenance and downtime when special fillers are added.
Plate is available in thickness from 4 mm to 30mm, and in standard square sizes (120, 160, 200, 250, 300, 400 and 450 mm square). Special sizes can be made to order, up to 100mm thick.Large diameter (520-1350mm) circular plates can be made. PTFE can be filled with materials like ekonol, glass fiber, molybdenum disulfide, carbon and bronze to increase hardness and change its properties for applications like bridge slides, brake linings and bearing pads.

Three main types of PTFE plates include:

＊ Molded PTFE Rectangular Plate I (Standard Size)
＊ Molded PTFE Rectangular Plate II (Large Size)
＊ Molded PTFE Circular Plate
