Liquid Silicone Rubber Overview

Global O-Ring and Seal offers custom parts made with liquid silicone rubber (LSR). Liquid silicone rubber components are injection molded in a Class 1000 cleanroom and can be formed into a highly specific end product. These fit especially well when producing components in accordance with PPAP. Parts made with liquid silicone rubber injection molding are used in a wide range of industries including the automotive, aerospace, and healthcare sectors.

Liquid Silicone Rubber Properties

The features of liquid silicone rubber products include:

  • Use in insulating or conducting electricity
  • Withstanding temperatures as low as -155ºF and as high as 392ºF
  • Customizable hardness from 10 to 80 Shore A durometer
  • Resistance to environmental conditions such as ozone, water, steam, and UV light while not showing significant aging
  • Biocompatibility with the end product being FDA-Grade and non-toxic

Why Choose Liquid Silicone Rubber Molding Over Compression Molding?

Lower costs are associated with prototyping and many manufacturing situations. The rapid cure cycle of LSR products allows the combination of existing components and then injection molding around them. This allows for reliable and repeatable processing in high-volume batches.

In the case of o-rings, liquid silicone rubber o-rings offer a much lower compression set than compression molded o-rings. Products made with Liquid silicone rubber retain their shape and flexibility after being twisted, compressed, and exposed to various temperatures. This makes LSR products formidable in both low and high-temp environments.
