Expect good resistance to extreme heat and cold, many oxidizing chemicals, and weathering. That behavior comes from the compound itself: Silicone delivers excellent electrical insulating properties and very good compression set resistance across its range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with concentrated acids or abrasive dynamic service.
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 pharmaceutical manufacturing, medical devices, and ovens and heated equipment.
SFDA3X13 ships individually. Unit weight is approximately 0.0064 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
