Polybutadiene
is an elastomer with properties very similar to natural rubber.
Its physical properties are not quite up to natural rubber. However,
in some cases its low temperature characteristics are better.
Butadiene is primarily a tire polymer.
SBR
rubber is probably best known under its old designation Buna S
or GRS (Government Rubber Styrene) which refers to the rubber
originally made during World War II in United States Government-owned
plants as a substitute for natural rubber.
However,
when the manufacture of this elastomer was turned over to private
industry, its designation was changed to indicate the chemical
composition; styrene and butadiene rubber. Tires account for most
of its usage.
Together
with SBR and natural rubber account for approximately 90% of total
world rubber consumption. Very little of these two materials is
used in seals.
SBR
is recommended for:
- Automotive
brake fluid
- Alcohols
(low molecular weight)
-
Water.
SBR
is not recommended for:
- Ozone
- Petroleum
Oils
- Sunlight
