Elastic materials obtained by special curing of high-silicon organic compounds. However, due to the special chemical structure, they have a number of remarkable properties that allow them to take a special place among the rubber elastic materials.

Flexible and elastic silicone sheets or tubes have a unique chemical structure that gives them, in contrast to any other elastomer, high thermal and chemical resistance and, as a result - they can work in the media where no other material can be used. This type of rubber sheet exceeds any other elastomers in its resistance to high temperatures and by far surpasses them as for its lifetime, it has a much lower compression set and antiadhesion properties, it is odorless, tasteless and non-toxic, it has excellent resistance to weathering, as it is not affected by the sunlight, ozone, moisture, dryness. Silicone rubber sheet (tube) has a smooth, defect-free surface. It can have different chemical composition giving it certain physical properties. Silicone rubber also has good chemical resistance. However, it may swell when exposed to certain solvents, but after evaporation of the solvent, typically silicon returns to its original size without losing properties. When exposed to maximum temperatures silicon rubber sheet practically emits no gas unlike other similar elastomers. It burns in an open flame, emitting non-toxic, odorless smoke and forms white ashes which do not conduct electricity. Silicone rubber is versatile by itself, yet, in spite of this, there are various modifications for operation under specific conditions.

Minimum working pressure (nominal) for food water, air and other media: *0.0 MPa. Minimum working pressure (nominal) for food and industrial oils, fatty foods, alcohol and alcohol-containing substances: 6.0 MPa. Shore A hardness: *5 - *5. Density: 1.**1,4 g/cm3 (depending on the type). Rated operating temperature: **0 º C … ***0 º C. Minimun tensile strength at break: 3.2 MPa. The sheet with thickness of 1 mm to 8 mm is manufactured in rolls of *0 kg each with the width of ***0 mm. The sheet with thickness *0 to *0 mm is produced in sheets of ***0 x ***0 mm.

Phenyl-based silicone rubber withstands the temperature up to - *5 º C, and if made by a special formula - up to - **2 º C. The operating temperature for ordinary sheets and tubes, **5 º C to ***0 º C, does not significantly affect the physical properties of silicone. Operation in the conditions of high temperature and pressure requires general purpose silicone rubber. Permanent deformation is dependent on the operating temperature, pressure and the operating environment. Silicone tubing and general-purpose sheet - technical, medical, and food, - are the most resistant materials for the given purpose. Fluorinated silicone rubber is the best choice wherever there is a contact with the fuel or solvent. This polymer has the best resistance to swelling and degradation from exposure to these substances. High-strength silicone materials with tensile strength of 6.**9.0 MPa and over make the best solution wherever there is a need for high elasticity, flexibility and tensile strength.
