What is liquid silicone rubber (LSR)？

Liquid Silicone Rubbers are two-part dispensible silicone supplies which are readily mixed and quickly heat-cured into durable elastomers. With superior processing time, reduced cycle times and lower production costs, liquid silicone rubbers might help together with your industrial and meals contact formulation wants.
Liquidsilicone for liquid silicone rubbers include liquid injection molding and coating. Dow’s IMAGIN3D™ Liquid Silicone Rubber is specifically designed for 3D printing.
LSR properties:

Biocompatibility: Under extensive testing, liquid silicone rubber has demonstrated superior compatibility with human tissue and body fluids and is hypoallergenic, making it a good selection for skin-contact products. In comparability to different elastomers, liquid silicone rubber is proof against bacteria growth and will not stain or corrode different supplies.
Tasteless and odorless: LSR is tasteless and odorless and could be formulated to comply with stringent FDA requirements required for food and beverage and baby products..
Durable: Liquid silicone rubber components can withstand extreme temperatures, making LSR a super choice for parts used in cars under the hood and in outside applications.
Chemical resistance: Liquid silicone rubber resists water, oxidation, and a few chemical solutions corresponding to acids and alkali. The material could be sterilized via quite a lot of methods, including steam autoclaving, ethylene oxide (ETO), gamma, e-beam, and numerous different methods used for medical and healthcare products.
Temperature endurance: Compared to different elastomers, molded silicone can withstand a variety of high to low-temperature extremes. It will stay steady in temperatures starting from minus 60 levels Celsius to a hundred and eighty levels Celsius.
Mechanical properties: Liquid silicone rubber has good elongation, excessive tear and tensile energy, glorious flexibility, and a hardness vary mostly between 5 to 80 Shore A.
Electrical properties: Liquid silicone rubber additionally has glorious insulating properties, helpful for a bunch of electrical purposes. Compared to traditional insulating materials, silicone can perform in far greater and lower temperatures.
Transparency and pigmentation: Liquid silicone rubber is inherently translucent. Its pure shade is white and conducive to pigmentation for producing customized, molded products in a big selection of colours.
Types Of Liquid Silicone Rubber
Liquid silicone rubber has differing types and compositions. Each kind has various traits.

silicone rubber liquid for making bushings
General Purpose LSR

This is a broadly used materials with intensive functions because of its flexibility, biocompatibility, and heat resistance. Typical uses of common objective LSR kind embody seals, gaskets, and industrial elements.


High-Temperature LSR
High-temperature liquid silicone rubber materials can stand up to extreme warmth exposure without degrading or compromising its qualities. Common purposes of this LSR include industrial equipment, automotive elements, and electronic components.

Medical Grade LSR
This type of liquid silicone rubber is formulated to fulfill the strict biocompatibility and safety requirements for medical and healthcare merchandise. Medical grade LSR materials are sterilizable and biocompatible, making them appropriate for applications that require contact with the human body.

Self-Bonding LSR
Self-bonding LSR material exhibits glorious properties of adhering to itself without utilizing different adhesives. Therefore, it's excellent for making complex assemblies with out depending on conventional bonding methods.

Food-Grade LSR
The food grade is much like the medical grade LSR. It meets strict requirements for contact with food and beverages. Baby products, baking molds, and kitchen utensils are typical food-grade liquid silicone materials purposes.

Electrically Conductive LSR
It accommodates electrostatic discharge (ESD) additives that provide electrical conductivity properties. This grade is usually utilized in functions with electrical conductivity and flexibility of silicone rubber requirements, including EMI/RFI shielding and flexible circuits.

Optically-Clear LSR
Optically clear liquid silicone rubber is appropriate for making merchandise like lenses, light guides, and other optical elements and gear with transparency and optical readability requirements.
