A ring-shaped, molded elastomer with a circular cross-section is what an O-ring is. Depending on the application, they may be built with unique cross-sections such as T-shapes, L-shapes, and so on.
Silicone is a type of elastomer composed of polymers derived from quartz that contains silicon, oxygen, hydrogen, and carbon. Methyl, phenyl, and vinyl are used in the manufacturing of silicone O-rings.
Properties of Silicone Rubber
Silicone is used in many applications where organic rubber cannot perform due to its excellent range of working properties.
- Excellent heat resistance
- Excellent compression set resistance
- UV and ozone stability
- Excellent resistance to oxidation
- Excellent water tightness
- Soft grades are also available (10, 20, 30 durometer Shore A)
- Abrasion resistance is poor.
- Chemical resistance is moderate to poor.
Specifications of Silicone O-Rings
Temperature Range
The temperature range of silicone O-rings is -60°C to 225°C. Temperatures can range from -100° to 300°C in some varieties.
General Suitability
Silicon is non-toxic and dermatologically compatible due to which it is most suitable for use in medical device and equipment assemblies.
Silicon O-rings are not suitable for dynamic applications due to their low strength, poor abrasion resistance, and high gas permeability.
Preferred Environment of Usage
Silicon O-rings are mainly preferred for use under high working temperatures due to their excellent heat-resistant properties. On being treated with chemicals they can also become flame resistant.
Environmental Properties
It is not recommended for use in concentrated solvents, oils, concentrated acids, diluted sodium hydroxide, hydrocarbon-based fuels, and aromatic mineral oil. Aromatic hydrocarbons (benzene, toluene), aromatic mineral oil, acids, alkalis, superheated water, or steam above 250 degrees Fahrenheit also have a degrading effect on silicon O-rings.
Applications of Silicon O-rings
Silicone O-rings are available in FDA-approved and medical-grade varieties. Silicone has become an important material for medical seals and devices due to its non-toxic biocompatibility. Microminiature silicone O-rings are becoming increasingly popular as medical technology becomes smaller and more compact.
Silicone O-rings are used in a wide range of other applications, including water-resistant camera housings, enclosures, automobiles, and many others.
