Type
820\821 PTFE Asbestos Packing & Filling Ring
It is woven
by adopting the high quality asbestos fiber with temperature-resisting
more than 300℃,which is soaked with PTFE latex. The product
has good performances of wearability,and the resistances
of alkali, weak acid,salts, organic solvents,liquid nitrogen,waste
liquid of paper pulp,seawater etc..

Type
811\810 Carbonized Fiber Packing & Filling Ring
Structure and feature: It is a cord shaped product made
by compounding PTFE and carbonized cord carbonaceous fiber
woven by feed-through braiding. This kind of product has
performances of good heat exchange, wearing-resistance,
chemical stability, high mechanical strength, and good self-lubricating
and less torsion space. The frictional heat is emitted easily
at the sealing place with high speed running. This kind
of packing has longer working life and is an ideal material
for various motion & motionless sealing.
Physical & chemical parameters:
1, Permitted working temperature: -60℃~400℃
2, Permitted working pressure: 190 kg/cm2
3, Max linear speed: 12m/s
4, PH: 5-11
5, Resilient ratio: 30%
6, Density: 1.4~1.7g/cm3

812 Carbonaceous Fiber Compounded Packing & Filling Ring
The products are woven by carbonaceous,
PTFE and armid fibers to be taken for main body of materials,which
are soaked with PTFE latex.This kind of filling packing
has good performances of chemical steady, self-lubricant,heat
transmitting and super low temperature.It can be fit for
high pressure and high speed sealing places with?low wearing
&tearing as well as less torsion space.The different combinations
can be decided according to the difference of working medium
and pressure.

Type 813 Preoxidation Thread Packing
It is a cord shaped sealing product
by wearing the preoxidation thread, which is taken for main
body of material and soaked with PTFE and special type lubricant.
The product has good performances of heat transmitting,wearability
and chemical steady.It also has high mechanic strength and
less torsion space. It is the ideal material for various
motion and motionless sealing.

829 Oil Yarn Packing
This product is soaked with special type lubricating grease,having
light-color.It cab be used for clear mediums.Structure:First,the
entwisted cotton threads?are soaked in advance.Then?the
further and more?sufficient?soaking is carried out during
the process of wearing.In the case of assuring the operating
limit,this kind of packing is very economic.

807 Ceramic Fiber Packing
It is made by ceramic fiber cord as
wick, outside which a layer of fire-resistant spun materials
is covered. This product is mainly used for purpose of fire-resistant
sealing, such as filling up the gap between firebrick and
wall of kiln, as well as the sealing between fire door and
firebox etc..It can be resistant for the high temperature
of 1300℃.

806 Glass Fiber Packing
The glass fiber has the advantage for
higher strength, better heat-resistant and lower price etc.
But, it is taboo due to its inadequate adsorbing characters
and higher hardness. It becomes possible only to make glass
fiber packing till to appearance of dilated glass fiber.
This is because of that there are lot of divarications on
glass fiber with fluffy structure, bigger than surface area
so that the adsorbent character is clearly improved. And
finally its frictional coefficient is reduced through being
pickled by PTFE latex or silicone oil.
As the glass fiber has performances of better heat-resistant
and acid-resistant, it can be used for shafts and valves
with lower speed.
