Strong Growth Opportunities for High-Transparency LSR

High-transparency LSR grades are increasingly specified for new high-power LED lighting technologies, which require materials that can retain optical clarity when exposed to high temperatures and ultraviolet (UV) light for long durations. Key outlets include automotive headlights and high-powered street and stadium lighting.


Because of transparency,  one side is the price of optical liquid silicone is fast three times of normal liquid silicone, and also the requirements for liquid silicone mold and liquid silicone molding processing are very higher.


Demand Study of Liquid Silicone Rubber Shown

expanding Range of Applications Drives Demand Growth for LSR

The US market for liquid silicone rubber (LSR) materials (i.e., the materials used to produce LSR molded parts) is forecast to increase 8.3% per year to $685 million in 2023, continuing robust growth as:


the range of applications for LSR – especially in the medical and automotive markets – continues to expand rapidly

more processors adopt production capabilities for LSR and become more familiar with complex molding techniques such as micromolding and 2-component (2K) molding


Fastest Growth in LSR Demand in medical Market

Other specialty LSR products gaining traction are grades that improve processing efficiency. Self-lubricating, self-adhesive, and non-post-cure types, for example, help eliminate additional fabrication steps such as post-curing and the application of coatings or binders.


Mainly LSR Materials Brand

The LSR materials industry remains highly concentrated, with the top five suppliers – Dow, Elkem Silicones, Momentive Performance Materials, Shin-Etsu Chemical, and Wacker Chemie – investing in the development of specialty LSR grades for the quickly expanding medical market.


MELON Rubber Engineer are familiar with LSR’s performance advantages, including fast processing speeds, precision molding, and biocompatibility.
