What Is LSR?

Liquid Silicone Rubber with a low compression set, fast cure cycles, great stability, and ability to resist extreme temperatures of heat and cold can makes itself being ideally suitable for the high standard quality production application. Unlike most thermoplastic elastomers, LSR remains flexible and elastic down to -60 centigrade and retains its properties up to 200 centigrade. In addition to these properties, the wide range of hardness, and colors, silicone elastomers have become the material of choice for an ever-increasing amount of applications.

Typical applications for liquid silicone rubber are products that require high precision such as seals, sealing membranes, electric connectors, multi-pin connectors, infant products where smooth surfaces are desired, such as baby nipples, medical applications as well as kitchen goods such as baking pans, spatulas, etc.

Characteristics of LSR:

Durable: LSR parts can withstand extreme temperatures, which makes them an ideal choice for components under the hood of cars and in close proximity to engines. Parts fabricated via liquid silicone rubber injection molding are fire retardant and will not melt.

Chemical resistance: Liquid silicone rubber resists water, oxidation, and some chemical solutions such as acids and alkali.

Temperature resistance: Compared to other elastomers, silicone can withstand a wide range of high/low-temperature extremes.

Mechanical properties: LSR has good elongation, high tear and tensile strength, excellent flexibility, and a hardness range of 5 to 80 Shore A.

Electrical properties: LSR has excellent insulating properties, which offer an appealing option for a host of electrical applications. Compared to conventional insulating material, silicone can perform in far higher and lower temperatures.
