Silicone rubbers have properties of both inorganic and organic materials. They are composed of unique silicone gums and high-purity silica. Silicone rubbers offer many outstanding features not found in other organic rubbers.
 
| |
Heat and cold resistance
|
|
|
At 150 ℃ there is almost no change in physical properties, and they maintain elasticity at temperatures at which typical organic rubbers become brittle.
|
| |
Weather resistance
|
|
|
Silicone rubber compounds can be exposed to UV rays, wind, and rain for long periods with almost no change in physical properties.
|
| |
Oil resistance, solvent resistance, chemical resistance
|
|
|
Silicone rubber compounds have superior oil resistance at high temperatures. They also have outstanding resistance to solvents and other chemicals, and are nearly impervious to polar organic compounds and dilute acids and alkalis.
|
| |
Electrically insulative
|
|
|
They are stable over a wide range of temperatures and frequencies. And even when immersed in water, there is almost no decline in performance.
|
| |
Compression set
|
|
|
They are stable over a wide temperature range (-60 ℃ to +250 ℃).
|
| |
Transparency and coloring
|
|
|
Silicone rubber compounds are highly transparent, meaning they can be easily colored with pigments.
