What Is the Use of Liquid Silicone Rubber?

Several diverse sectors employ LSR components. It is a great option for components that need to be created in a sterilization-and-environment-controlled setting, such as an ISO clean room, because of its purity and resilience to steam, heat, and moisture. Gaskets, seals, and diaphragms used in water heaters, gas furnaces, dishwashers, and other household appliances must function in harsh conditions. LSR is employed in many areas of a car, including the engine compartment, EV battery packs, sensors, and electrical connectors. This is because many automotive components require oil and heat resistance, improved sealing features, and vibration and insulative properties.

LSR Parts' Qualities

LSR's distinct chemical structure is what gives it its distinct material features. A sequence of siloxane linkages, which are more powerful and stable than carbon bonds, make up its backbone. This enables silicone rubber liquid to be:

chemically unactive

Since liquid silicone rubber has an organic core, it is chemically inert and does not interact with other substances in any way. Along with a number of alkali or acid products, LSR is also resistant to harm from water, oxidation, UV rays, ozone, and radiation. LSR has the chemical qualities to function effectively in these circumstances for items used outside, in harsh settings, or subjected to regular cleaning.


LSR is naturally non-toxic and hypoallergenic, so it won't irritate or aggravate allergies in those with sensitive skin. LSR offers a secure and pleasant solution for respiratory goods like oxygen and CPAP masks, as well as items like earphones, hearing aids, or wearable monitoring devices worn for extended periods of time.

The molecular makeup of LSR also adds to its biocompatibility. It does not taste or have an odor. It is extensively used in infant goods and other items connected to food and drink since it also conforms with Food and Drug Administration (FDA) regulations.

Physical Features

LSR is chosen above other elastomeric polymers because of its superior physical and thermal stability qualities. Depending on the grade, LSR may withstand temperatures as high as 200 degrees Celsius and as low as -40 degrees Celsius without losing any of its physical characteristics.

Additional physical traits consist of:

LSR components will maintain their form when squeezed.

LSR features a surface with a naturally smooth texture.

Modulus: LSR provides both stiffness and flexibility.

LSRs are frequently used for their sealing qualities.

Responsive: Ideal for delicate sensing membranes, sensitive and responsive

Insulating: Electrically and thermally insulating by nature,

Hardness: Available in a variety of durometers, although 10 to 80 Shore A durometers are the most often utilized.

Molded components made of liquid silicone rubber have no taste or odor. Utilizing pigments and masterbatches allows for the creation of distinctive hues and visual effects. Some components are also UV and ozone-safe.

Uses for Liquid Silicone Rubber

You might be wondering at this point what precisely silicone rubber is used for. A very adaptable material, liquid silicone rubber is always being studied and used in novel ways. It is a staple in the creation of healthcare devices, automotive components, electronics, consumer goods, gaskets, and other hardware, among many other sectors.
