Sealing rubber rings of circular section
Sealing rubber
rings of fluoroelastomer РЎРљР¤ 26 considerably exceed the products of
hydrocarbon rubber (lump or acrylate); they are meant for operating in
especially difficult service conditions. To the chemical stability
fluoroelastomers excel all known elastomers. They are steady to the concentrated
and weak mineral acids and alkalis, many aliphatic and aromatic chlorinated and
unchlorinated carbohydrates, benzine, oils, lubricants and gas.
Depending on demands and operating conditions, the rings are made of different
rubber types with fluoroelastomer РЎРљР¤ 26, the solidity level from 55 to 95
(under РЁРћР Рђ) and attrition strength to 14 J/mm.
Seal rubber rings, made of fluoroelastomer rubber РЎРљР¤ 26
, approved themselves in petrochemistry, while running in oil, tar, phenol,
chlorbenzene, silicon organic liquids, weak acids, alkalis, and hydrogen sulfide
mediums. In oil and fuel medium the rings are operable at the temperature from
-20oC to +300 (long-term running) and even to +350 (short-term running). In acid
and alkalis solutions the rings are operable at the temperature from -20oC to
+200 (long-term running) and even to +250 (short-term running).
Seal rubber rings of butadiene-nitrile rubber are characterized by a higher
specific elongation (to 450%) and lower thermal limit fragility (to -60oC). Seal
rubber rings made of butadiene-nitrile rubber showed themselves in oil
production, while running in oil mediums, containing to 30% aromatic additives,
and in formation and silicon organic water. In the engine and transmission oil
mediums the rings are operable at the temperature from -60oC to +150 (long-term
running) and even to +180oC (short-term running). In the hypoid and solar oil
medium the rings are operable at the temperature from -60oC to +140 (long-term
running) and even to +160oC (short-term running).
Rubber rings of ethylene-propylene rubber approved themselves in energetics,
while running in the spirits, ether, ketone, air, steam, alkali, and mud fluid
mediums. In the air and steam medium the rings are operable at the temperature
from -50oC to +200 (long-term running) and even to +300oC (short-term running);
in the acid and alkali solutions the rings are operable at the temperature from
-50oC to +180 (long-term running) and even to +250oC (short-term running).
