It is a braided packing made of PTFE yarn containing graphite particles and anti-corrosive lubricant. It is recommended for shafts for almost all chemicals. Stability and long service lift are achieved by low friction coefficient. It has great tear strength and high thermal conductivity. This self-lubricating packing does not score the shaft and minimizes sleeve replacement cost. It can be used to seal alkalis, solvents, water, steam, acids except strong oxidizing acids(aqua regia, fuming nitric acid, fuming sulfuric acid, etc.) forcentrifugal pumps, autoclaves agitators, mixers, etc.
