Nitrile can also be compounded with carboxylic acid groups
to create XNBR or Carboxylated Nitrile, which has a greater
abrasion resistance as well as more tensile and tear strength.
Nitrile rubber can also be hydrogenated to create (HNBR),
a rubber with greater physical strength and minimal degradation
over time.
SBR: Styrene Butadiene, Buna-S, GRS
SBR offers excellent abrasion and impact resistance
with a typical service temperature range of between -55ºC
and +85ºC. It has properties similar to those of
natural rubber. SBR and natural rubber account for nearly
90% of the world’s rubber consumption, since SBR
is used in the manufacture of tires. SBR is recommended
for applications where water, automotive brake fluid,
or alcohols with a low molecular weight are present. The
typical durometer range is between 40 and 90.
Neoprene: Polychloroprene (CR),
Chloroprene rubber
Neoprene is characterised by its versatility. It
has good mechanical strength, it is ozone and weather
resistant, and has good aging resistance. It also not
very flammable, bonds well to metal and has a good resistance
to certain chemicals. Typical service temperature is between
-40ºC and +135ºC and it is available in durometers
ranging from 30 to 95. Neoprene can be formulated for
use in mass transit industries due to its ability to meet
ASTM c1166, e162, e662 and SMP800C standards.
Natural Rubber: (NR)
Natural rubber is fairly easy to
process. It has good low temperature properties, excellent
elongation and a high resistance to tears and abrasions.
Its useful temperature range is between -55ºC and
+ 85ºC, and it can be easily bonded to metal. Unfortunately
natural rubber exhibits poor resistance to ozone, oxygen,
sunlight, solvents and oils. Its typical durometer range
is between 30 and 90. |
