Silicones are a group of elastomeric materials made from silicone, oxygen, hydrogen, and carbon. Extreme temperature range and low temperature flexibility are characteristics of silicone compounds. As a group, silicones have poor tensile strength, tear resistance, and abrasion resistance. Special compounds have been developed with exceptional heat and compression set resistance. High strength compounds have also been made, but their strength does not compare to conventional rubber. Silicones possess excellent resistance to extreme temperatures -50°C to + 232°C (-58°F to +450°F). Some special compounds resist even higher temperatures. Retention of properties of silicone at high temperature is superior to most other elastic materials.
Silicone compounds are very clean and are used in many food and medical applications because they do not impart odor or taste. Silicone compounds are not recommended for dynamic O-ring sealing applications due to relatively low tear strength and high coefficient of friction. Silicone is resistant to hot air, ozone, UV radiation, engine and transmission oils, animal and vegetable fats and oils, and brake fluids. VMQ also has low resistance to mineral oils. Silicone can be compounded to be electrically resistant, conductive, or flame retardant. Many silicone compounds have a higher than normal mold shrinkage. Therefore production moulds for silicone products are often different than molds for nitrile.
VMQ rubber compounding
VMQ (blue frame) improves vulcanisation rate, compression set, resilience and oil resistance. These elastomers have excellent cold flexibility (can reach temperatures of -50 °C) as well as high thermal resistance (up to 200°C, with special compounding up to 300°C for short periods of time).
They have very good resistance to ageing and attack by oxygen, ozone and sunlight. They also have excellent dielectric and anti-adhesive properties as well as low toxicity and can therefore be used in many food and medical applications since they do not impart odour or taste. In general they have poor tensile strength (<15MPa) and tear resistance compared to conventional rubber.
Resistance to mineral oils (depending on grade) and fuels is moderate however, but they have good resistance to animal and vegetable fats and oils, brake fluid and engine oils. The most admirable property of this polymer is its very wide service temperature range. Silicones also show poor gas impermeability.
