NATURAL RUBBER [NR] [IR] [SBR]This is available in many grades, from pure latex to filled mixed qualities for specific

uses (i.e. Bridge Bearing rubber, Snow Blade rubber). Although highly acid and

abrasive resistant Natural rubber is not generally used for weathering and should

not be used with oils. The temperature range of -40�C to +80�C does not normally

allow this material to be used in non-ambient environments. Often this group

includes Isoprene (IR) and Styrene Butadiene (SBR). Again natural rubber is

available in solid or sponge sheet form.

Most of the above rubbers can be supplied with reinforcement either in the sheet

or on top or bottom (as in the case of belting material). This basically increases the strength of the material and is

normally required when sealing against higher pressure, or in the case of diaphragm material, where pressure

accompanied by continuous flexing occurs. Simple coated fabrics are also available for use as covers, aprons, skirts


NEOPRENE [CR]Chloroprene, generally known under the DuPont trade name of Neoprene, this


is probably the most commonly used synthetic rubber. With a temperature

range of -20�C to + 100�C and good resistance to oils, chemicals and ageing,

the material is also

flame retardant. Available in solid or sponge form.

Neoprene [CR].


Acrylonitrile-Butadiene Rubber has excellent resistance to water, oil and fuel with superior compression set and

abrasive resistance. The temperature range is -20�C to 110�C and the material is used generally for sealing in

automotive type applications. Not particularly resistant to ozone or weathering this material is also available in solid

and sponge form.

BUTYL [IIR]With a fine molecular structure, Butyl is aptly suited to Gas and Water sealing with

its very low permeability. Having a temperature range of -50�C to + 120�C, Buty

also has excellent ageing, ozone and chemical resistance. Although good for ester

based hydraulic oils and electrical Applications, Butyl is not suitable for use with

petroleum Oils and fluids.


Ethylene Propylene rubber has very good resistance to weathering and general

chemicals however it should not be used with petroleum products. Also available

to meet Water Research Council requirements it is widely used in the potable water

markets. With a temperature range of -40�C to + 120�C EPDM is also suitable for

steam and glycol ether fluids.


This material is available in sheet form for many applications. Being very hard wearing it is particularly suited to

applications where high durability is required, such as scraper blades and press tools. The material is resistant to oils,

many solvents, greases and ozone however it should not be used with acids or alkalis or at elevated temperatures.



SILICONE [Q Grp]Although not suitable for use with mineral oils this material is normally used where

high temperatures are involved, having a temperature range of -60�C to +250�C.

Silicone also has very good electrical properties and is suitable for outside use,

however it has poor tensile strength, tear, abrasion and steam resistance. This

material is available in solid or sponge where required.



Chlorosulphonated Polyethylene Rubber (or Hypalon, the DuPont trade name, as it is better known) has excellent

weathering, abrasion, acid and flame resistance. It is often used as an intermediate grade between lower grade

synthetic rubbers and Viton. With a temperature range of -20�C to + 120�C this material is becoming increasingly used

in automotive ‘under-bonnet’ applications, and is now regularly used as a binder with cork for this purpose.
