Silicone Properties
The first practical silicone rubbers
were introduced in the mid 1940’s. Since then continual improvements
have been made. Today a broad range of physical properties are available
including:
|
| Useful
temperature range |
-175
ºF to 500+ ºF |
| Hardness,
Shore A |
20
to 90 |
| Tensile
Strength, psi |
up
to 1,600 |
| Elongation,
% |
up
to 1,000 |
| Tear
Resistance, ppi |
up
to 300 |
| Compression
Set, % |
down
to 8 |
| Specific
Gravity |
1.0
to 2.1 |
| Volume
Resistivity, Ohm-cm |
1015
to 1017 |
| Electric
Strength, volt/mil |
600
to 650 |
| Dielectric
Constant (60 cps) |
3.0
to 3.5 |
In addition to these properties silicone
rubber also offers: long service life, inertness, and good chemical, weather,
flame, and radiation resistance.
We at Laur Silicone are proud to have
played a part in these improvements, and remain committed to further progress.
