Expanded graphite braided packing is
made from expanded pure graphite yarn, braided into packing through all kinds
of technology of braiding. It can be divided into expanded graphite braided packing
with inconel or steel wire inserted, expanded graphite braided packing with
fiberglass, expanded graphite braided packing impregnated with cotton fiber.
The product are almost suitable to all media, such as hot water, steam, acids,
alkalis, organic solvents, hydrocarbons, low temperature liquids, etc. The
sealing capability is more better and safety. It is the most effective
composite parts for solving problems.

PGP 3200 Braided PTFE Graphite Packing.
This kind of product is
made by combining PTFE with graphite. Because in this kind of composite
material, both PTFE and graphite have good self-lubrication property, so the
products have very low friction factor and good self-lubrication property too.
Thus, axles of machinery will not be scratched and the cost for changing axle
sleeves will be decreased to a great extent. Owing to good heat conductivity of
graphite, working temperature of packing can be increased, hence the working
life will be longer. Furthermore, they almost suit to all of chemical media.
??These packing are widely applied to sealing at
operating places where contamination is not permitted, for example, for sealing
of pumps, valves, flanges in equipment of foodstuff, pharmaceutical, wine-making,
petroleum, chemical, power, paper making, printing and dyeing industries.

PGP 4100 Carbon fiber braided packing with PTFE dispersion.
This
packing made of high-quality carbon fiber, impregnated with PTFE dispersion. Because carbon fiber has quite high strength and good heat
conductivity and PTFE makes the packing have very good self-lubrication
property, thus the product possesses properties of fine anti-chemical
corrosion, self-lubrication and heat conductivity, then it will not damage pump
shafts and has long working life. It's suitable for almost all corrosive media,
organic solvents and mainly used for centrifugal pumps, plunger pumps, mixers
and valves.

PGP 5100 Kevlar fiber braided packing dipped with PTFE dispersion.
This kind of
packing is made from braiding of aromatic polyamide yarn (Kevlar), which is
first dipped with PTFE emulsion then treated with lubricant and inhibitor of
corrosion, finally braided to form square cross-section. Because Kevlar yarn has
excellent properties with very high strength and module (It is called artificial
steel wire.). So compared with other kinds of braided packing, it can resist
more severe media and higher pressure. It can be installed separately from other
kinds of packing as well as combined with others to from packing sets of
different characteristics to be used as end rings.
This kind of
packing is mainly used as substitute of asbestos in pump system. Not only is
protects environment but also its property is better than asbestos. Even if
under very bad conditions where ordinary asbestos packing can't provide
satisfied service effect, this kind of packing can do. In addition, its working
life is very long, sealing effect more better and it is often used at bad
conditions, such as: water pumps at mortar site, tin mine, pulp factory and
power plant.
