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
The temperature range of silicone O-rings is -60°C to 225°C. Temperatures can range from -100° to 300°C in some varieties.
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.
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.
