Molykote 33 Medium Grease for Extreme-Temperature Plastic Gearse
Basic Properties
Molykote 33 Medium is a silicone-lithium soap grease, white color, NLGI grade 2, density 0.98 g/cm³, base oil viscosity 100 mm²/s@25°C. Engineered for metal/plastic friction pairs across -73°C to 180°C.
Product Description
33 Medium achieves 207 mN·m starting torque @-73°C and 1,400 N weld load. ≤4.5% bleed rate @150°C and ≤3.5% evaporation ensure longevity. 100 mbar oxidation pressure drop delivers superior protection.
