AT515 Thepacking is braided from Kevlar fibers with PTFE impregnation andlubricant additives. It has extremely high intensity, chemical resistantproperty, high elasticity, low heat expansion, good lubricity and heatconductivity. Suggestion: the surface hardness of the shaft or shaft lagshould reach 40-60HRc in order to avoid the surface abrasion.
Suitableto be used in the abrasive mediums with solid granules. Suggested to beused in high temperature steam, solvent, liquefiable steam, syrup, andother abrasive liquids. It can be used separately, or combined withother packing such as installing in partition, or as an end ring.
