Characteristics of several common rubbers

Rubber is an indispensable material in the production of solenoid valves.
Therefore, the understanding of the

nature of rubber is an important basis
for distinguishing the characteristics of different solenoid valves.

1.NBR (nitrile butadiene rubber) has excellent oil resistance, high wear
resistance, good heat resistance and

strong adhesion. The disadvantages
are poor low temperature resistance, poor ozone resistance, poor
electrical properties, and slightly lower elasticity. In addition, it has good
water resistance, air tightness and

excellent bonding properties. NBR has
excellent oil resistance, its oil resistance is second only to polysulfide
rubber and fluororubber, and it has wear resistance and air tightness.The
disadvantage of NBR is that it is not

resistant to ozone and aromatic,
halogenated hydrocarbons, ketones and ester solvents. It is not suitable
for

insulating materials.

2. EPDM (Ethylene Propylene Diene Monomer) The most important
characteristic of EPDM is its superior

resistance to oxidation, ozone and
erosion. It absorbs a large amount of fillers and oils and has little effect on
properties.' This property makes EPDM resistant to heat, light, oxygen,
and especially ozone. Features: low

density and high flling; aging
resistance; corrosion resistance; water vapor resistance; overheating
resistance;

3.VITON fluororubber (FKM) is superior to most rubbers in high
temperature resistance; chemical resistance,

most oils and solvents
(except ketones and esters), weather resistance and ozone resistance
are good, but

cold resistance is poor; It is widely used in the seals of
steam locomotives and chemical plants. It has a

temperature range of
-20°C to 260°C. When it is used at low temperatures, it has a low
temperature resistance

and can be applied to -40.C.
