SBR (Styrene Butadiene)
A synthetic elastomer suitable for low to medium duty
applications involving air, water and diluted mixtures for,
economic, general purpose applications.
NR (Natural Rubber)
NR natural rubber compounds have high abrasion
resistance with excellent resilience, tensile strength,
elongation, tear strength and mechanical properties It is
highly flexible and has good low permanent set qualities It
is not recommended on higher temperature applications
CR (Chloroprene) – Neoprene
A multi-purpose material suitable for applications involving
weathering, sea water, mineral oils, greases, dilute acids
and alkalis but is not recommended for fuel immersion It
also exhibits good flame retardant properties dependent on
polymer content
NBR (Nitrile Butadiene) – Nitrile
Excellent resistance to petroleum oils and aromatic
hydrocarbons, mineral oils and many acids with good
elongation, resilience, tensile and compression set
properties
EPDM (Ethylene Propylene)
Excellent resistance to water (fresh and sea), oxidation,
ultra violet, ozone and weathering coupled with good
temperature resistance It also has good resistance to
acids, water based chemicals and vegetable based
hydrocarbons but is not recommended for use with mineral
oils and di-ester based lubricants
IIR (Isobutylene) – Butyl
Very high impermeability to gases, ozone, ultra violet light
and weathering with high chemical and acid resistance and
is particularly good when applications involving high and
low temperatures prevail
CSM (Hypalon®)
Outstanding resistance to most chemicals and oils at
high and low temperatures with excellent weathering and
abrasion resistance It also has low moisture absorption
and good dielectric properties.
