Grease is a thick emulsion system consisting of:

Base Oil: usually accounts for 70–90%, can be mineral, semi-synthetic, or synthetic oil.
Thickener: accounts for about 5–20%, determines the “type of grease” (Lithium, Calcium, Polyurea, etc.).

Additives: about 1–5%, such as anti-wear, anti-oxidation, heat-resistant, water-resistant, etc.

Grease Type	Characteristics	Typical Applications
Lithium Grease (Lithium Soap)	Most common, good heat resistance (~130–180°C), average water resistance	Motorcycles, trucks, bearings, electric motors
Lithium Complex Grease	Higher heat resistance (>200°C), good adhesion, heavy-duty	Construction equipment, Specialized Vehicles
Calcium Grease	Inexpensive, good water resistance but poor heat resistance (max ~80°C)	Sliding bearings, slow rotating bearings, wet equipment
Polyurea Grease	Non-soap, extremely long life, excellent oxidation resistance	Sealed motors, long-term maintenance-free equipment
Aluminum Complex Grease	Good adhesion, water and food resistant	Food processing equipment
Graphite, Moly (MoS₂) Grease	Extreme pressure (EP) resistant, dry friction resistant	Heavy-duty bearings, construction vehicles
Silicone Grease	Chemically super durable, cold and heat resistant (-50 → >200°C)	Plastic valves, rubber gaskets, medical equipment
