Nitrile (NBR) Rubber Properties
- A universal, oil resistant rubber
- A good quality general purpose nitrile sheet
-
Recommended where added resistance to mineral oils,
alcohols and petroleum is required especially under hot conditions
-
It is not recommended for use in sunlight, or near
sparking electrical apparatus
Neoprene Rubber Properties
- A good general purpose poly-chloroprene sheet
-
Recommended for use in less demanding situations with air,
water, non-oxidizing acid and aliphatic hydrocarbons or where
extra resistance to heat, ozone or weathering is required
EPDM Rubber Properties
-
This material has good mechanical properties and is resistant
to ageing, weathering, ozone, oxygen, steam and water
-
Recommended for use where resistance to sunlight, weather,
steam and ozone attack is important
-
Suitable for use with phosphate ester-based hydraulic fluids
and many mineral acids
-
Not suitable for use with petroleum based oils or fluids
Viton Rubber Properties
-
High temperature rubber material with resistance to a wide
range of chemicals
-
A high quality fluorocarbon rubber which exhibits wide range
of chemical resistance
-
Extremely resistant to the effects of oxygen and Ozone
-
Retains excellent mechanical properties even when subjected
to high temperatures for long periods of time
Butyl Rubber Properties
-
This material is resistant to phosphate ester based hydraulic
fluids and mineral oils
-
It is highly impermeable to gas and moisture but is not
recommended for petroleum oils and fluids
-
Good resistance to phosphate ester based hydraulic fluids
and many mineral oils
-
It is highly impermeable to gas and moisture and has good
general chemical resistance including mineral acids
-
Resistance to petroleum oils and fuels is low
Natural Rubber Properties
- A good general purpose poly-chloroprene sheet
-
Recommended for use in less demanding situations with air,
water, non-oxidizing acid and aliphatic hydrocarbons or where
extra resistance to heat, ozone or weathering is required
-
A medium quality commercial grade which exhibits the qualities
required for a good gasket
-
Suitable for gaskets and packing where no particularly high
resistance to heat, oils or solvents is required e.g. cold water,
sewage pipes, etc.
Silicone Rubber Properties
-
A high quality silicone rubber with excellent resistance to
temperature extremes
-
Good weathering properties and can be used in contact with
foodstuff's and a white silicone rubber is also available
Cork Gasket
-
Rubber cork is a composite material made by combining
natural cork granules with rubber, often bound with
polyurethane. This mixture is valued for its versatility and
excellent physical properties, making it suitable for a wide
range of industrial applications, particularly in the seal
and insulation sectors.
-
Cork is available as natural, resin bonded and rubber
bonded. Rubber bonded cork is used for gaskets.
Cork gaskets vary depending on the size of the granules
used to manufacture the material and the base rubber
compounds with which the material is bonded
(commonly neoprene or nitrile).
-
Known for their use in sealing wine bottles, cork materials
make relatively cheap and effective seals, with good oil
resistance properties. Due to these properties, cork
gaskets are typically used in: sumps, crank case covers,
inspection doors, valve covers, electrical transformer
gaskets, general cover and lids, electrical switchgear and
for anti-vibration purposes.
-
These gaskets are also often used in the automative
industry for carburettors, fuel and oil pumps, thermostats
and gearboxes. They are ideal for use on irregular
surfaces or with uneven bolt loading.
-
Different grades of cork have different temperature and
pressure ratings, so please ask if you have a particular
specification that needs to be met.
-
Rubber cork combined the ability of cork to compress
within itself (e.g. so bottles don’t break) and rubber
which is only diplaced. This combination makes it an ideal
low compression seal.
