Silicone Rubber Mechanical Properties

Silicone rubber properties.

Silicone rubber mechanical properties.

Silicone elastomers are one subgroup of silicone polymers. Silicone polymers or polydialkylsiloxanes are an important class of inorganic polymers that find many industrial uses. Liquid silicone rubber is a low viscosity and high purity thermoset elastomer maintaining mechanical properties over a wide range of temperatures from 50 c to 250 c. Various grades of silicone rubber have different material properties.

Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. There are different types depending on functional groups in the structure and curing mechanisms. This heat cured elastomer is an excellent solution to consider if you re looking for highly optical clarity combined with long term durability in harsh environment high. Mechanical properties of silicone rubber in a closed volume g.

Key properties include thermal stability chemical stability electrical insulation and low toxicity. Silicone rubber can be immersed in water cold water warm water boiling water for long periods with water absorption of about 1 and with virtually no effect on mechanical strength or electrical properties. The mechanical properties of platinum cured liquid silicone rubber lsr platinum cured high consistency rubber platinum cured hcr and peroxide cured high consistency rubber peroxide cured hcr was investigated. 12189 approved for public release.

These silicone o rings and other parts are thin flexible and resistant to temperature extremes and chemical damage. Main applications are flexible seals o rings etc. Distribution unlimited electe f s fed 13 0o. Because of this liquid silicone rubber possesses material properties such as a high degree of elasticity and compressibility as well as water repellence and good releaseability.

Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations. The results provide a complete picture of the effect of sterilization on the physical properties of silicone rubbers typically. Methyl vinyl silicone rubber matrix composites filled with alumina al 2 o 3 powder and cnts were fabricated through a conventional mechanical blending method the effects of the mass fraction surface modification of al 2 o 3 powder and the addition of. They are known for their outstanding temperature and oxidative stability excellent low temperature flexibility and high resistance to weathering and many chemicals.
