Liquid Silicone Rubber Is A Two-Part Platinum-Cured Elastomer That Can Be Injected Into A Mold Cavity To Manufacture Parts

 

Liquid Silicone Rubber

Liquid Silicone Rubber (LSR) is a type of elastomer that is made from a two-part platinum-cured silicone material. It is a highly versatile material that offers a unique combination of properties, including high thermal stability, excellent chemical resistance, and remarkable flexibility, making it an ideal material for various applications in a wide range of industries.

Liquid Silicone Rubber is made through a process called dynamic vulcanization, which involves the mixing of two liquid components, the silicone base material and a catalyst. The mixture is then subjected to high pressure and temperature to initiate the curing process. This results in the formation of a highly elastic and durable material that can be molded into complex shapes and sizes.

One of the primary benefits of Liquid Silicone Rubber is its high thermal stability, which allows it to operate over a wide temperature range, from -65°C to 200°C, without any significant degradation in its properties. This makes it an excellent material for applications in high temperature environments, such as automotive and aerospace industries, where it can be used as seals, gaskets, and hoses.

Liquid Silicone Rubber also has excellent chemical resistance, making it ideal for applications in the medical and pharmaceutical industries. It is non-toxic and biocompatible, which means that it can be safely used in contact with human skin and internal body parts. It is also resistant to various chemicals and solvents, including hydrocarbons, acids, and alcohols, making it ideal for use in harsh chemical environments.

In addition to its high thermal stability and chemical resistance, Liquid Silicone Rubber also offers remarkable flexibility and elasticity, which makes it an ideal material for applications in the consumer goods industry. It is commonly used to produce items such as kitchen utensils, baby products, and electrical components, where its flexibility and durability provide a comfortable and long-lasting user experience.

Another important advantage of Liquid Silicone Rubber is its low compression set, which refers to the amount of permanent deformation that occurs when a material is subjected to a compressive load. Low compression set means that LSR retains its original shape even after repeated use, making it ideal for applications where dimensional stability is important, such as in the automotive and aerospace industries.

LSR also offers good electrical insulation properties, making it ideal for use in electrical and electronic applications, such as in the production of cables and connectors. Its high resistance to electrical arcing and tracking, combined with its flexibility, also make it ideal for use in high voltage applications.
