Liquid silicone rubber (LSR) is a versatile material that has found extensive use in various industries, including the medical industry. It is a high-performance polymer that has revolutionized medical manufacturing by providing superior characteristics such as biocompatibility, durability, and flexibility. In this article, we will explore what LSR is, its applications, and how it has transformed the medical industry.

What is Liquid Silicone Rubber?

Liquid silicone rubber (LSR) is a type of silicone elastomer that is composed of a two-part liquid component. The two-part component consists of a silicone base, which is typically vinyl-terminated polydimethylsiloxane, and a curing agent, which is usually a platinum catalyst. These two components are mixed in a 1:1 ratio and cured at high temperatures to form a solid, elastomeric material.

LSR has excellent mechanical properties, such as high elongation, tear strength, and low compression set. It is also chemically inert, biocompatible, and has good thermal stability, making it suitable for a wide range of applications, including medical manufacturing.

Liquid Silicone Rubber VS Solid Rubber

Compared to solid rubber, LSR has some unique advantages. Firstly, it can be injection-molded into complex shapes and geometries with high precision, allowing for the production of intricate medical parts. Secondly, LSR has a low compression set, which means that it maintains its shape even when subjected to compression or deformation, making it ideal for applications where accuracy and consistency are crucial.

Thirdly, LSR is more durable than solid rubber, with better resistance to wear and tear, chemical exposure, and temperature extremes. Lastly, LSR is biocompatible, which means that it does not react with living tissues, making it an ideal material for medical implants and devices.
