PTFE & GRAPHITE FIBER PACKING
Material:It is a braided packing made of PTFEyarns coated with graphite. It is recommended for shafts for all most all chemicals.Stability and long service lift are achieved by low firiction coefficient.
Characteristics:It has great tear strength and high thermal conductivity. This self-lubricated packing doesn’t score the shaft and minimizes the sleeve replacement cost.
Application:It can be used to seal alkalis,solvents,water, steam,acids except strong oxidizing acids (aqua regia, fuming nitric acid, fuming sulfuric acid, etc.) for centrifugal pumps, autoclaes, agitators, mixers, etc.
