Silicon is the second largest element on Earth, making up 28% of the earth's crust, and is found in sand, silicates and many minerals such as quartz. Silicon and oxygen atoms join to form long chains of polymers, which form rings to make silicone. These polymers look like coils and function like buffers . This coil, unlike other molecules, can be coiled or unwound under environmental conditions.

They exist in a range of forms from gaseous to brittle solids and can be manufactured in a wide variety of viscosities, densities, structures and functions. The unique combination of properties of this coil has inspired industrial production to produce many previously unimaginable products.
Unique performance

The unique properties of silicone cover a large number of functions. Most notable is the excellent temperature resistance. Silicone remains stable at -90-330°C. This fairly wide range contrasts sharply with most organics, which begin to solidify above 0°C and begin to fade and oxidize at 120°C. Due to its inherent ultraviolet (UV) resistance and oxidation resistance, silicone is weather-resistant, making it ideal for outdoor use. Silicone does not fade and crack over time as organic matter does.

Silicone is also perfect for use in electronics because of its electrical insulation properties close to those of glass. In addition, special ozone and corona resistance makes it suitable for high voltage applications. Silicones provide excellent water resistance and immersion stability, so they can also be found in underwater instruments. As a kind of rubber, silicone resin is used in gasket and seal field because of its high compressive deformation resistance. Its own bonding ability is used for conveyor belts in ovens for baking foods, and can also be used in elastic molds for injection materials and low melting point alloys.

Silicone has exceptional uv resistance and can be used in high-energy lighting, instrumentation and solar installations. Since the 1950s and 1960s, when a number of artificial hearts were investigated, silicone's biocompatibility has led to its use in a variety of implants, wound care and drug delivery systems.

Performance determines purpose

There is no single market for silicone, but thousands of niche markets across many industries, disciplines and functions. The following are examples of specific applications of silicone, so it can be said that it is a versatile material.

One of the first applications was during World War II, in 1943, silicone rubber gaskets were used on b-29 searchlights and superchargers 3. No other material can withstand such extreme temperatures. In the late 1940s, this primary use spawned an industry. Industrial gaskets and sealants, along with some applications of high-temperature rubber, have led to explosive market growth. It quickly expanded into the automotive, aerospace and professional markets. At this time, the hot vulcanized silicone rubber industry has been established.

RTV silicone is the first silicone rubber product accepted by the vast user market. It has been widely used since it was introduced in 1960. Silicone is considered superior to other sealants because of its resistance to extreme temperatures and its ability to adhere to a variety of substrate materials without a base coat. They can also be used in construction, glass assembly, medicine, aviation, aerospace, manufacturing, electrical and electronic products and automotive markets. Today, the largest consumption of silicone is in the construction industry. RTV silicone sealants for filling are widely used as mobility seals for automobiles due to their ability to withstand high temperatures in a variety of conditions. Silicone is the only elastomer that remains well pliable at -45°C and is therefore also used in the refrigeration industry. This capability also allows silicone to be used in aerospace. As the only elastomer that remains flexible at low temperatures, the silicone on astronauts' lunar boots was the first material to touch the moon in 1969. In addition to its low temperature flexibility, silicone's ability to resist ultraviolet light has led to applications in satellites and spacecraft.

In the field of electronic pooping adhesives, such as some mobile phones, silicon gel provides moisture, dust and water proof seals, as well as mechanical shock/shock absorbers and electrical insulation properties. Their low modulus and high stress dissipation capacity produce internal vibration damping, which determines their use. In addition to high corona resistance and high voltage ionization resistance, silicone itself is an excellent electrical material and insulation material. So silicon resin can be used in many high voltage electrical and electronic fields. Wire insulation and cable terminations are also very typical silicone rubber applications. In those areas, they can include more than 90% of organic cable materials of the same size as the current standard 3. And when the insulated wire is ignited, the external thermoelectric insulation forms ash, thus maintaining operational capacity. Silicone thermal insulation can also upgrade the top of the section of the extremely hot platform to the wooden counter. In addition, the characteristic data of silicone rubber can also be used in heat transfer fields, such as speakers and heat sinks for portable computers. Conductive parameters can be applied to touch screens, electromagnetic interference (EMI) and rf interface devices. Other numerical characteristics can be described as flame retardancy.

For more than 40 years, all glass aquariums have been assembled and sealed with room temperature curing (RTV) silicone due to their long-term water resistance and excellent glass bonding properties. Another unique use of the newly generated RTV silicone is for permanent pant leg seams.
