II PACKINGS SERIES
1 Expand Graphite Braided Packing
Product Code: GD-1112Expand graphite braided packing, made of expanded graphite
yarn braids, is resistant to heat, chemicals, and tight in sealing. It
is widely used in the steam valves of power plant, or as static
sealing in places where high temperature and pressure,or
chemical corrosion(except concentrated sulphuric acid or strong
oxidizing agents)prevails.
Application:
Max.working temperature: 850(in non-oxidized atmosphere)
450(in oxidized atmosphere)
Max.working pressure:25.0 Mpa
PH value: 0~14
2 Carbonized Fiber Braided Packing
Product Code: GD-1210
The packing is manufactured in the following procedures:
polyacrylonitrile fiber is heated into carbonized fiber, which is woveninto packing after impregnation in PTFE dispersion containing
graphite particles. It is used as dynamic sealing in the presence of
media of weak acid or alkaline, or media that contain few grains of
solid particles.
Application: Max. working temperature:260
Max. working pressure:10.0Mpa
PH value: 2~12

3 Carbon Fiber Packing With Graphite
Product Code: GD-1316The packing is woven of strong carbon fiber after softening
treatment and impregnation with the mixture of fine graphite
powder, PTFE dispersion and lubricant. Being strong, static and
heat-conductive, It is widely used with revolving or reciprocating
pumps, where media of chemical corrosion and grains of particles
exist.
Application: Max. working temperature:600
Max. working pressure:25.0Mpa
PH value: 0~14
4 PTFE Braided Packing
Product Code: GD-1555
The packing, made of raw film twists of pure PTFE dispersion
resins, is suitable for valves and pumps used in food processing,
pharmaceuticals, paper mills, fiber plants, where high purity and
corrosion resistance is required.
Application: Max. working temperature:260
Max. working pressure:2.0Mpa
PH value: 0~14
5 PTFE Braided Packing With Graphite
Product Code: GD-1516
The packing is woven of graphite PTFE yarn twisted through a
mixture of PTFE dispersion resins and fine graphite powder plus
moderate amount of heat-resistant lubricant. Apart from its
corrosion resistance, it has thermal conductivity and
self-lubricating properties, and is suitable as dynamic sealing in
places where media flow at high linear velocity(about 16m/s).

Application: Max. working temperature:280
Max. working pressure:4.0Mpa
PH value: 0~14
6 Reinforced PTFE Braided Packing
Product Code: GD-1740
The packing is reinforced with non-organic fiber PTFE raw film,
thus eliminating the cold flow property of PTFE and enhancing its
resistance to chemicals and weathering. It is widely used with
valves and revolving pumps for media of weal alkaline or strong
acid liquid so as to avoid contamination.
Application: Max. working temperature:260
Max. working pressure:10.0Mpa
PH value:0~12
7 Reinforced PTFE/Graphite Braided Packing
Product Code: GD-1174
The packing is made of corrosion-resistant and tensile fiber cords
that have been impregnated with the mixture of PTFE dispersion
and fine graphite powder. It is further impregnated withheat-resistant lubricant so as to be used more efficiently with
revolving pumps in water plant, where water contains
low-concentration particles.
Application: Max. working temperature:280
Max. working pressure:10.0Mpa
PH value: 0~12
8 PTFE Braided Packing Of Multi-Filament Yarn
Product Code: GD-1500
The packing is made of pure PTFE fiber that have been
stretched and reinforced, then impregnated with PTFE
dispersion. It is applicable to various media owing to its high
tensile strength and low frictional properties. However, it is

recommended as dynamic sealing in places where linear velocity is up to 4m/s, for
PTFE is a substance with low heat conductivity and great thermal expansion coefficient.
Application: Max. working temperature:260
Max. working pressure:6.3Mpa
PH value: 0~14
