Gland Packing
PTFE Split-yarn Braided Packing
Braided from PTFE split yarn and impregnated with PTFE emulsion. With low friction, high lubricity, high strength and non-contamination, it is stable against strongly corrosive media such as acid, alkali and solvent, used for corrosive pump and valve sealing, especially where hygiene grades are required. Suitable for all media except fuming sulfuric acid, fuming nitric acid, aqua regia, fluorine and other strong oxidizers; the preferred packing for food, pharmaceutical and hygiene industries.
