| Standard Color: Blue |
| Working Temperature Range: -30° C to + 110° C |
PU
is premium polyurethene for superior sealing performance for use in
general hydraulic applications (Not suitable for hot water), it has
excellent mechnical properties such as high tensite strength, abrasion
resistance, tear strength, and extrusion resistances. |

| Nitrile Rubber (NBR) |
Top |
|
| Standard Color: Black |
| Working Temperature Range: -40° C to+ 100° C |
Nitrile
Rubber is general purpose elastomer for Hydraulic and Pneumatic
systems and used as seal energizer for low pressure applications such
as pneumatic, it has excellent resistance to mineral oil, greases,
water, hydrocarban fuels, compression set resistance and good elastic
properties, it is not suitable to automotive brakes fluid. |

| H-NBR Rubber |
Top |
|
| Standard Color: Black |
| Working Temperature Range: -25° C to 150° C |
HNBR
rubber, improves wear and extrusion resistance over standard NBR,
HNBR has outstanding resistance to heat, ozone, weathering, mineral
oil, crude oils, with amines, fuels, greases, aliphatic hydrocarbons,
and indurtrial chemicals, it has very good mechanical properties and has
extended high temperature range. |
| |
| EPDM Rubber |
Top |
|
| Standard Color: Black |
| Working Temperature Range: -45° Cto +150° C |
EPDM
has good resistance to ozone ageing and weathering, water and steam,
Dilute acid, alkalies ketones, alcohol, fire retardent hydraulic
fluids and hydraulic brakes fluids, this elastomer must not come in
contact with mineral oils and greases. |
| |
| Silicon Rubber |
Top |
|
| Standard Color: Orange |
| Working Temperature Range: -60° C to+ 200° C |
Silicon
Rubber has great cold flexibility as well as high thermal resistance.
It has excellent de-electric properties and very good resistance to
attack by oxygen, ozone and sunlight. It has poor strength & tear
resistance to mineral oils. |
| |
| Polychloroprene Rubber (C R) |
Top |
|
| Standard Color: Black |
| Working Temperature Range: -20° C to+ 100° C |
CR
chief characteristice is flame retardency, excellent ageing
properties in ozone and weather environments along with resistance to
abrasion and flex faitigue. It is good resistance to mineral oils with
high aniline point, greases refrigerants and water. |
| |
| Fluorinated Rubber FKM(Viton) |
Top |
|
| Standard Color: Brown |
| Working Temperature Range: -30° C to+ 220° C |
Viton
Rubber is excellent resistance to mineral oils, hot water, steam,
fuels, alcohol, hot oils, aliphatic and aromatic hydrocarbon, it has
poor resistance to methanol, ketones & esters also exhibits
excellent chemical resistance for use in harsh environments such as
phosphate esters. |
| |
| Poly Acrylic Rubber |
Top |
|
| Standard Color: Black |
| Working Temperature Range: -10° Cto +125° C |
| Poly
acrylic Rubber has excellent resistance to heat, hydrocarbon, oil,
mineral oxidation and ozone. But poor resistance to water, steem,
acids and alkalis. |
| |
| PTFE / VIRGIN |
Top |
|
| Standard Color: White |
| Working Temperature Range: -195° Cto+ 250° C |
| Used
mainly for o-rings, backup rings and machined parts used in special
applications requiring chemical inertness and limited strength. Ideal
for use in cryogenic applications |
| |
| PTFE/ Glass Filled PTFE |
Top |
|
| Standard Color: Off-White |
| Working Temperature Range: -195° C to +250° C |
| Typical
application: Used where there is a need for improved wear and
increased coefficient of friction. Ideal for high dynamic applications
e.g. high rotation pumps |
| |
| PTFE/ Bronze filled PTFE |
Top |
|
| Standard Color: Bronze |
| Working Temperature Range: -195° C to +250° C |
Typical
application: Used in dynamic sealing applications where the bronze
filler gives improved wear resistance, hardness and compressive
strength. The electrical properties and chemical resistance are reduced.
Molybdenum disulphide improves the self lubrication |
| |
| PTFE/GRAPHITE filled PTFE |
Top |
|
| Standard Color: Black |
| Working Temperature Range: -195° to+250° C |
Typical
application: Significant increased thermal conductivity, reduced
level of creep. Self lubricating, therefore suitable for high speed
applications, without the need for exterior lubrication and
applications which need to remove thermal energy and/or static
electricity |
