SILICONE PROPERTIES

Laur Silicone will match the properties you need to your application. 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:

TitleTemperature
Useful Temperature Range-175 ºF to 500+ ºF
Hardness, Shore A20 to 90
Tensile Strength, psiup to 1,600
Elongation, %up to 1,000
Tear Resistance, ppiup to 300
Compression Set, %down to 8
Specific Gravity1.0 to 2.1
Volume Resistivity, Ohm-cm1015 to 1017
Electric Strength, volt/mil600 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.
