High Resilience Kevlar Gland packing Low Cold Flow Chemical resistance
Descriptions:
Kevlar packing is braided from Kevlar which is dipped in emulsion and treated with lubricant.Normally used at dynamic sealing and static sealing location for particle crystal medium.the Kevlar fiber features super high strength and perfect wear and tear resistance. Normally used as stop ring at medium end (where a lot particle crystal are existed)and used together with other kind of packing.
Kevlar Packings is a high quality aramid fiber impregnated PTFE and lubricant additive. Good chemical resistance, high elasticity, low cold flow. Nature has excellent high speed, high modulus (called artificial metal line)
The high quality DU PONT Aramid Fiber dips PTFE emulsion and lubricating additives. The most outstanding performance is high strength, meanwhile a relatively good chemical resistance,higt resilience,low cold flow. Althoug it is quite wearing resistant, used improperly, it will wear out the pump shaft, so we recommend the surface hardness pf the pump shaft and the protection sleeve reaching 60HRC. This packing is inner dipped the mixture mainly silicone oil, it si easy to assemby-disassembly fast and conveniently. It is a universal type packing, which is widely used in various industry areas, chemical, refinery, medical, food, sugar making, paper making and electric power,etc. This packing is durable, suitable for wear medium containing solid particles, recommended using for overheat steam, solvent, alcohol vapor, syrup and other wear fluid. It can be used for 160°C hot water under coolant-free circumstance. It can be singly used, or combine with other packing, put in the two ends, as an extrusion-proof ring.

Applications
Widely used in various industrial fields, such as chemical industry, oil refining, pharmaceutical, food, sugar, paper and power industries; pump, valve and mixer is often used for rotating equipment.
Although mainly designed as a rotary pump packing, Kevlar packing is also suited for valves and piston pumps, mixers and reactors in the following industries: pulp and paper, pharmaceutical, food, sugar, chemical and petro-chemical, power stations, steel mills and many more. Also ideal as anti-extrusion rings in combination with softer packing.
