This material stands up to many oxidizing chemicals, extreme heat and cold, and weathering. That behavior comes from the compound itself: Silicone is valued for very good compression set resistance across its range and an exceptionally wide service temperature range. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across medical devices, ovens and heated equipment, and sanitary process lines.
Order part number SFDA2.5X8, sold individually. Unit weight is approximately 0.0064 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
