AFE-CA Grease
AFE-CA Grease is a clean environment grease that uses a high-grade synthetic oil as a base oil and uses a urea-based thickener to achieve extremely low dust generation.
Features
Low dust generation
Among THK's low dust generation greases, this is the grease with the lowest dust generation. Since it contains no metal elements, it is ideal for use in the semiconductor field.
