820-1 lubricating oil is a non-volatile viscous liquid with medium molecular weight and stable chemical properties. It is refined by using new nano materials and base oil and adding antioxidants, preservatives, antifriction agents and other additives. After volatilization or thermal decomposition at high temperature, it will not form residues, which is used for the production of copper clad aluminum bus.

1. Performance characteristics:

　　★ Good lubricating performance and oil film strength prevent scratches and defects on the outer surface of the copper-clad aluminum wire when it is stretched .

　　★ Good water resistance, impermeable to water vapor, and hydrophobic.

　　★　Good oxidation resistance and high temperature resistance.

　　★ Good viscosity-temperature performance, strong adhesion to metal, low fuel consumption.

　　★ It is non-flammable, non-corrosive, non-toxic, non-odor, and has no adverse effects on the human body.

2. Physical and chemical properties:

3. matters needing attention:

　　★ Store in a cool and dry place, pay attention to seal, prevent water from immersing, and cannot be used with water

　　★ If it touches the skin, wash it off thoroughly with detergent, soap and water

　　★ Shelf life: 2 yearsPackaging: 170kg/barrel
