What are Silicone properties?
Silicones are polymers made up of siloxane – a chain of alternating silicon and oxygen atoms frequently combined with carbon and/or hydrogen. They are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost. In its natural state, silicone rubber is a highly-adhesive gel or liquid. Only when cured, vulcanised or catalysed does it convert to a solid.
The outstanding characteristic of Silicone rubber materials is that they are generally non-reactive, stable, and resistant to extreme environments and temperatures. Trade names include Rhodosil and Elastosil.
What is Silicone rubber commonly used for?
There are multiple formulations of Silicone rubbers including: steam resistant, metal detectable, high tear strength, extreme high temperature, extreme low temperature, electrically conductive, chemical/oil/acid/gas resistant, low smoke emitting, and flame-retardant. Typical uses include:
- Aerospace in the form of O-Rings, Seals and Gaskets in gas turbine, piston and jet engines.
- Food & dairy
- Instrumentation & Electronics due to its electrically insulative or conductive properties it is suitable for a wide range of applications.
- Medical devices and orthopaedic products due to its durability and bio-compatibility.
- Motorsport & Specialist Automotive seals & gaskets.
- Subsea, Oil & Gas connectors repelling water and with great thermal stability.
