Mineral Fiber Packing

Mineral Fiber Packing
PA 2500 Arcylic Fiber Packing with PTFE

Braided from high strength arcylic synthetic fiber pre-impregnated with PTFE, and re-impregnated during square braiding. It has excellent properties of sealing, lubricating and resistance to chemicals.
2500G is acrylic fiber packing with oil and few PTFE
2500SC is Arcrylic fiber packing with silicon core
 

PA 2500G Arcylic Fiber Packing Treated with Graphite

Braided of high strength Arcylic synthetic fiber, treated with graphite.
The packing is then re-impregnated during braiding consisting of graphite mixed with special lubrications. Much of graphite filler increases the service temperature and the density of the packing.
APPLICATION:

2540 Kynol Fiber Packing`

 
Braided from high-performance Kynol (also named novoloid or phenolic) fiber impregnated with special PTFE lubricant, it has very good mechanical properties combining softness and strength. The packing has natural golden sheen. Compared to ordinary aramid and PTFE, it has more benefits as follows:
 
★    Thermal stability, low heat expansion;
★    High dimensional stability and superior pressure resistance even at elevated temperature;
★              Good process-ability, easy to cut and fit;
★              Outstanding chemical resistance particularly in acidic media;
★              Excellent resistance to organic solvents, oil and fuel...
 
APPLICATION:
 
A high performance packing that is well suited to applications where graphite impregnation may not be acceptable. Suitable for abrasive media, and where contamination is not permitted. It has multiple uses in chemical plants and pulp and paper mills, and is regularly used in rotating and reciprocating pumps, washer journals, liquor pumps, refiners and digesters.

Glass fiber is standout among the different organic and inorganic fibers as ideal replacement of asbestos. All of Aiflon glass products are made of good quality E-glass fiber, it has many excellent capabilities of high strength and high temperature resistance, low density and low thermal conductivity, better insulation and incombustible etc.

2600 Glass fiber packing

Braided from E-glass fibers without any impregnation, untreated, will not shrink or swell in service. May be ordered square or with a rectangular cross section.
It can be reinforced by nickel wire, stainless steel etc. on request----Style 2600I
2600G Glass fiber packing with graphite impregnation
Square braided from E-glass fiber impregnated with graphite. It also can be reinforced by nickel wire etc. on request------Style 2600IG

2600P Glass fiber packing with PTFE impregnation

Square braided from E-glass fiber impregnated with PTFE, that largely prevents solids from entering the seal and maintains its elasticity.

2602 Twisted Glass fiber rope

A dry, flexible rope.

2604 Round braided Glass fiber rope

Stronger and more stable, also can be reinforced by nickel wire and so on-----Style 2604I
2606 Braided Glass fiber lagging rope
APPLICATION:
As a static seal for vessels, heaters, manhole, lids, covers, thermal insulation and fire-proof of pipes etc. Suited for chemically neutral and resistant to water, steam, hot air, oils and so on.
