Description
Technical field
The present invention relates to anti-chemical technology field, be specially a kind of nitrile rubber (NBR) low temperature and resist cold formula.
Background technology
Nitrile rubber is a kind of universal oil resistant rubber, is widely used in the hydraulic pressure steam-operatings such as petroleum machinery, vehicle, engineering machinery
System.As sealing member goods, its excellent elastic characteristic is suitably employed in various oil pressure pipeline, and it had both had good resistance to
Oily, resistance to smelly, wear-resisting and chemicals-resistant corrosivity, has again good compression set and heat resistance, but NBR low temperature resists cold
Property poor, low temperature retraction (TR10) only at-45 DEG C.If ground uses below-45 DEG C, easily cause due to loss of elasticity sealing
Disabler, directly affects use, and its safety and stability performance is a greater impact.
