Information About Dow Corning? 510, 550 and 710 Fluids

Type

Phenylmethyl polysiloxane Physical Form

Silicone fluid

Special Properties

Heat resistance; high flash points; low volatility; radiation resistance Primary Uses

Hydraulic arrestors (snubbers); hydraulically actuated valves and instruments used in nuclear plants; other applications where radiation exposure exists DESCRIPTION

Dow Corning? 510, 550 and 710 Fluids

have radiation resistance of approxi-

mately 1.7 x 108 rads.

Dow Corning 510 Fluid is available in

a viscosity range of 50 to 30,000 cs,

Dow Corning 550 Fluid has a viscosity

of 125 cs and Dow Corning 710 Fluid

has a viscosity of 500 cs. Dow Corning

550 and 710 Fluids can be blended to

provide any viscosity between 125 and

500 cs.

Other characteristics include:

?Thermal stability – Dow Corning 510,

550 and 710 Fluids demonstrate

exceptional high-temperature

stability during continuous use at

232°C (450°F); these materials are

also suitable for low-temperature

applications requiring pour points

as low as -57°C (-70°F)

?A phenyl group on the polymer chain

?Chemical inertness – Silicone fluids,

including Dow Corning 510, 550 and

710 Fluids are inherently inert,

resulting in no corrosion of metals

or adverse effect on the seals

commonly used in the construction

of snubbers, valves and instruments

?Ability to swell silicone rubber

?Low flammability – Dow Corning 510,

550 and 710 Fluids exhibit a flash

point in excess of 274°C (525°F), a

fire point of 343°C (650°F) mini-

mum and an autoignition tempera-

ture in excess of 482°C (900°F)

?Compressibility – The relatively high

compressibility of these fluids makes

them ideal for use in shock

absorbing and motion dampening

applications (see Table I)

?Heat transfer – Because of their

excellent oxidation and tempera-

ture resistance, these fluids can be

used to transfer heat; heat conduc-

tivity is relatively constant over a

wide temperature range

?Compatibility – Dow Corning 510

Fluid is incompatible with both

Dow Corning 550 and 710 Fluids;

however, Dow Corning 550 and 710

Fluids are compatible and miscible

with each other – compatibility with

other silicone fluids should be

determined before use

LIMITATIONS

These products are neither tested nor

represented as suitable for medical or

pharmaceutical uses.

USES

Dow Corning 510, 550 and 710 Fluids

are ideally suited for applications such

as hydraulic arrestors (snubbers),

hydraulically actuated valves and

instruments used in nuclear plants,

and other applications where

exposure to radiation is a possibility.

SHIPPING LIMITATIONS

None.

STORAGE AND SHELF LIFE

When stored in their original,

unopened containers at 25°C (77°F),

Dow Corning 510 and 550 Fluids have

no known limits to useful life. When

stored in its original, unopened

The melt point temperature is a typical value and may vary somewhat due to molecular distribution (especially 50 cs or less). If melting point is critical to your application, then several lots should be thoroughly evaluated.2

Due to different rates of cooling, this method may yield pour points lower than the temperature at which these fluids would melt.
