Description
Orapi 620 SITEF is a silicone grease additivated with micronized solid lubricants with very low friction coefficient (PTFE).
SITEF has been developed in a range of various consistencies in order to cover the friction torque specifications of the lubricated assemblies.
Advantages
- very high stability to heat. Can be used even at low temperatures.
- total physiological inertia, can be used for incidental contact with food. Complies with the following requirements :
- France : CNERNA 1992
- USA : FDA regulations 178 3570-USDA H1
- very low friction coefficient on metallic, plastic, elastomer materials.
- good resistance to solvents.
- good perfomance to extreme pressure frictions.
- does not stain.
Meets the requirements of the aerospace industry : PQ 81600
Application Fields
- low speed ball bearings.
- all alloys taps, valves.
- pneumatic mechanisms, distributors, jacks.
- elastomers, polymers lubrication. Recommended for mixed friction (metal, rubber).
- assembling and greasing under vacuum for several industries : the chemical industry, the refrigeration industry, refineries, industrial bakeries, sterilization
