Supreme Silicones SS GR 500 High-Vacuum Grease is a stiff, non-melting silicone lubricating material that maintains its consistency from -40 to 225°C. SS GR 500 High-Vacuum Grease is recommended for vacuums reaching between 1 x 10-5 and 1 x 10-6 mm Hg. It is recommended that the grease be preconditioned under vacuum and temperature until these limits are reached.

PERFORMANCE DATA: Chemical Resistance SS GR 500 resists vegetable and mineral oils and common gases. It also resists aqueous solutions of inorganic salts and dilute acids and alkalis. Securing or including complete information on variables such as pressure, flow velocity, re lubrication schedules and valve construction is impractical. For this reason, the suitability of SS GR 500 Grease should always be tested before the material is adopted for regular use
