|Molecular formula: [CF2--CF2]n
Properties and Applications
In addtion to all excellent properties of PTFE material, CGF-206 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 CGF-206 extruded straps : 5.0mm, 4.5mm, 3.2mm, 2.8mm.
Processing of the oil-free unsintered tape
PTFE CGF-218 for broad width tape (no less than 250mm)
