Description
CR-Neoprene :
U.S.A. In 1953
CR is the first synthetic rubber, manufactured by
polymerising chlorine and butadiene.
Feature : Heat resistance, oil and chemical, ozone,
weathering, flexing compression set and flame.
Application : Many sealing applications.
U-Urethane/Polyuretane
:
Feature : High resistance petrolium oil, fuels, ozne
and weathering
Application : Prefer for hydraulic systems and high
pressure, shock loads, wid metal tolerances, not recommended
for acids, ketone and chlorinated hydrocarbons.
Trade Name : Texxin by Mils Chemical, Apiprene by
Uniroyal, Cyanaprene by American Cyanamid, Pellethane
by Dow Chemical
NBR-NItrile :
Copolymer of acrylonitrile
and butadiene
Feature : Good resistance to oil fuel and petrolium
products, gasoline, tear, abrasion, re-enforce NBR,ozne
and sunlight.
Application : Widely used elastomer for sealing applications.
EPDM/EPM-Ethylene
Propylene (Polyolefin rubbers)
Feature : 2 Types EPM-Saturated Polymer and EPDM-Unsaturated
Polymer.
Application : Popular in sealing industry ; good resistance
to skydrol and phosphate ester type hydraulic fluids.
Flexing characteristic and good heat resistance and
electrical properties and wide range of temp. -57
to + 150 C application.
Trade Name : Nordel by E.I. Dupon, Vistalon by Exxon
