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.
