Silicone delivers excellent electrical insulating properties and an exceptionally wide service temperature range. Expect good resistance to weathering, many oxidizing chemicals, and ozone and UV exposure. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to hydrocarbon fuels and oils or steam above its rated range will shorten service life.
This item meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. You will find this material specified across medical devices, electronics and electrical enclosures, and ovens and heated equipment.
Stocked as SFDA4X38 and sold individually. Unit weight is approximately 0.0064 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
