Silicone is valued for excellent electrical insulating properties, physiological inertness and low toxicity. It resists many oxidizing chemicals, dry heat, and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with steam above its rated range or concentrated acids.
The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across pharmaceutical manufacturing, ovens and heated equipment, and sanitary process lines.
Stocked as S70MD047 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
