PTFE wässrigen Dispersion

1.Molecular Structure: -(-CF2-CF2-)n- 2.Properties of the emulsion: With polymer solid content 60% (w/w), the mean particle size of the colloidal PTFE dispersion particles is 0.05 0. 5 micron. With high stability against coagulation. Nontoxic at room temperature. Excellent chemical inertness, outstanding resistance to chemical corrosion, such as strong acid, alkali, strong oxidant, etc. Outstanding resistance to heat, low temperature and abrasion. Can be used at temperature range from -200 +250 for long time. Excellent electric insulation property, which is not affected by temperature and frequency. Adhesiveless. No absorption of water. Flame-retardation, etc. 3.Main Application: Directly used in impregnating porous materials, such as asbestos, glass fiber, metal, ceramics and electric carbon as anti-corrosion, sealing, antifriction and lubricating materials. Can used as protection layer by spraying or brushing on many kinds of metal or non-metal matrixes. Can be directly used in PTFE spinning. Wildly applied in national defence industries,rubber and electrical industries, etc. PTFE SFN-1B is similar to the general-purpose PTFE SFN-1,except that it has a smaller particle size. This could offer advantage in spray coating processing.4.Specification: ItemPX-PADAppearanceMilky white emulsionSolid content60%S.S.G.2.15 2.27Viscosity7 14 mm2/s (25 )Melting point317 337Average Particle size0.16 0.32 micronSurfactant Content6%PH value7 9
