From robot wheels to automotive seals, we do it all. We welcome the opportunity to be of service to you.
Silicone rubber is available in hardness ranges from gels all the way up to 80 Shore A durometer, (refer to durometer chart), in translucent and opaque colored versions.
Silicones maintain flexibility at low temperatures; have low compression set; have outstanding resistance to high heat, sunlight, oxidation, ozone and exhibit good corona resistance. Most of our standard silicones are temperature rated from -150º F to 650º F. Some of our high performance silicones can operate in a continuous environment from -150º F to 650º F with excursions to 850º F. Silicones provide a non-stick surface for many processes. FDA approved and class VI medical materials are available.
Properties of Silicones:
- Silicones are available in hardness ranges from gels all the way up to 80 Shore A in translucent and opaque colored versions.
- Silicones have the widest working temperature range of elastomers. Typically -150 to +500° F.
- Silicones have low compression set.
- Silicones are suitable for outdoor applications. They have outstanding resistance to sunlight, oxidation and ozone.
- Some of our silicones can operate in a continuous environment of -150º F to 850º F.
- Silicones are fungus resistant, odorless, tasteless and non-toxic.
- Silicones are strong, resilient and stretchable at temperatures where organic rubbers fail.
- Silicones are not compatible with many organic substances; therefore provide better release characteristics than any other rubber.
- Silicones retain good dielectric strength even at elevated temperatures.
- Silicone rubber does not give off toxic materials while burning.
- Silicone rubber absorbs energy over a wide range of frequency and temperature for vibration dampening.
- Silicone rubber resists radiation damage similar to other synthetic elastomers. However, at high temperatures silicone rubber offers a combination of thermal, oxidation, and radiation resistance not available in any other elastomer. Some silicones will withstand radiation dosages of 110 megarads at room temperature and 30 megarads at 400° F.
- Silicone rubber also exhibits good corona resistance.
