NLGI #1: Lowest stiffness
Food Grade Classification: NSF H1 (NSF Registration No. 136725)… meets FDA 21 CFR specifications for incidental food contact
Use: It is used in a variety of applications that require: wide range of thermal stability, high dielectric strength, electrical insulation, inertness to rubber and plastic surfaces, and insulation against corrosion and moisture.
Silicone Grease NLGI#1 is inert to virtually all substrates with the exception of silicone rubber. * It is often used for lubricating o-rings, gaskets, valves and seals as well as surfaces that require excellent lubricating properties over long periods without drying out. It is not recommended for metal-to-metal lubrication or on surfaces that will be painted or finished.
