JDVII-6831E Polymethacrylate (PMA) VII
Product Introduction
JDVII-6831E is the solution of polymethacrylate in deeply refined mineral oil, which can effectively improve the viscosity index of oil, save the amount of pour point depressor, and the price is reasonable. Compared with similar products, it has huge economy and can effectively save production costs.
Product Performance
- JDVII-6831E is a viscosity index improver with high shear stability.
- It has excellent low temperature performance and has a smaller dosage in the mixing process of low temperature hydraulic oil and other oils.
- It can effectively improve the viscosity index of oil and save the amount of pour point depressor.

* Noted: Add 10% viscosity index improver to HVI 150 base oil to make thickening oil, and measure its viscosity increase value at 100ºC, which is the thickening capacity.
Recommended Dosage
Recommended dosage: The recommended dosage for JDVII-6831E is 1 to 10%, depending on the actual application. For details, please consult our additive application engineer.
Packing And Precautions
Net weight: 170 Kg/drum, packed in 200 liter metal drum. Non-flammable, non-explosive, non-corrosive.
Please refer to SH/T0164 for transportation, storage and handling. Best Blending temperature: 50-60ºC. Storage temperature below 60ºC, avoid repeated heating, keep away from heat.
