VMQ - MVQ - Sillicone - O-Rings - 70 Shore A - Transparant

What is a Silicone O-ring - 70 Shore A Transparent

A Silicone O-Ring - 70 Shore A - Transparent is a sealing ring made of VMQ (Vinyl Methyl Silicone) with a hardness of 70 Shore A. This O-ring is transparent in color and is known for its excellent thermal and chemical properties. The material withstands temperatures from -60 °C to +200 °C, and with special grades, this can even reach up to +230 °C.

Silicone O-Rings - 70 Shore A - Transparent contain silicon, oxygen, hydrogen, and carbon and are often used in applications requiring a wide temperature range and good chemical resistance. These transparent silicone O-rings are particularly suitable for environments exposed to water, ozone, weather conditions, and aging. Additionally, they are resistant to vegetable and animal oils and fats, as well as aliphatic motor and transmission oils.

Properties of Silicone O-ring - 70 Shore A Transparent

A Silicone O-Ring - 70 Shore A - Transparent offers a unique combination of properties that make them suitable for various applications. The transparent color allows for visual inspection without removing the seal. VMQ silicones are particularly resistant to extreme temperatures, ranging from -60 °C to +200 °C, and can even withstand short-term temperatures up to +230 °C.

Additionally, these O-rings are resistant to water (up to 100 °C), ozone, weather conditions, and aging. They maintain their flexibility and performance at low temperatures and are resistant to bacteria and fungi. However, a Silicone O-Ring - 70 Shore A - Transparent has low resistance to aromatic mineral oils, steam above 120 °C, silicone oils and greases, fuels, and strong acids and alkalis.

The advantages of a Silicone O-ring - 70 Shore A Transparent

A Silicone O-Ring - 70 Shore A - Transparent offers various advantages for industrial and commercial applications. The wide temperature range of -60 °C to +200 °C makes it suitable for use in both very cold and very hot environments. Thanks to the excellent resistance to chemical fluids, including vegetable and animal oils and fats, these O-rings are ideal for applications in the food and medical industries.

The transparent color allows for visual inspection, which helps in quickly identifying any issues without removing the seal. Moreover, a Silicone O-Ring - 70 Shore A - Transparent retains its properties even under prolonged exposure to high temperatures and ozone, increasing its lifespan and reliability.

Applications of a Silicone O-ring - 70 Shore A Transparent

A Silicone O-Ring - 70 Shore A - Transparent is widely used in various industries due to its unique properties. In the medical and pharmaceutical industries, they are used because of their excellent resistance to bacteria and fungi and their ability to provide sterilizable seals. In the food industry, these O-rings are popular due to their chemical resistance to oils and fats and their transparent color, which allows for visual inspection.

These transparent silicone O-rings are also used in the automotive sector for sealing in engine and transmission systems, where they are resistant to aliphatic motor oils and transmission fluids. Other applications include electronics, where the thermal stability and insulating properties of a Silicone O-Ring - 70 Shore A - Transparent are important.

Disadvantages of a Silicone O-ring - 70 Shore A Transparent

Despite the many advantages, a Silicone O-Ring - 70 Shore A - Transparent also has some disadvantages. A major drawback is their low resistance to aromatic mineral oils, fuels, and strong acids and alkalis, which limits their use in environments where these substances are present. Additionally, these O-rings are not resistant to steam above 120 °C and silicone oils and greases, which can limit their use in certain industrial processes.

Furthermore, they have relatively low mechanical strength and tear resistance, making them less suitable for dynamic or rotating seals where high wear occurs. This makes a Silicone O-Ring - 70 Shore A - Transparent susceptible to damage under shear forces, which can affect their durability and lifespan in certain applications.
