Silicone Rubber is made from silicone, oxygen, hydrogen, and carbon; it can be compounded to be electrically resistant, conductive, or flame retardant.
Its unique characteristics include an ability to cope with high extremes of temperature in excess of 240°C it also remains flexible at temperatures as low as -65°C. Whilst in general silicones can exhibit poor tensile strength, tear resistance, and abrasion resistance there are specialist compounds that have been developed which can increase certain properties for more specialised applications, high strength compounds have been made, but their strength still does not compare to natural rubbers.
When cured correctly Silicone compounds are very clean and can be used in many food and medical applications because they do not impart odour or taste. Due to the relatively low tear strength and high coefficient of friction Silicone compounds are not recommended for dynamic O-ring sealing applications. Silicone has low resistance to mineral oils but has excellent resistant to hot air, ozone, UV radiation, engine and transmission oils, animal and vegetable fats and oils, and brake fluids.
