Details

PTFE Aqueous Dispersion SFN-1

Description:
SFN-1 is an aqueous dispersion of PTFE for general purposes with properties as below
 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 oC ~ +250 oC for long time.
 Excellent electric insulation property,which is not affected by temperature and frequency.
 Adhesiveless.
 No absorption of water.
 Flame-retardation,etc.
Applications:
 Be Directly used in impregnating porous materials,such as asbestos, glass fiber,metal,ceramics and electric carbon as anti-corrosion, sealing,anti-friction and lubricating materials.
 Be used to make protection layer by spraying or brushing on many kinds of metal or non-metal base substances, with presence of primers.
 Be directly used for PTFE spinning.
