Low-temperature hydraulic oil PMA Viscosity modifier |
||||||||||||||||||||||||
PMA is a kind of the efficient viscosity index improver, and it is also the efficient pour point depressant for the lubricants with excellent performances. With a little dosage, this product can availably improve the viscosity index, and can also reduce the pour point at the same time. The product is transparently sticky liquid. And the dosage has no effect on the transparence of the oils. A little dosage of PMA can keep the performance of keeping the lower pout point durably. It can be used for formulating many kinds of the oils such as aviation hydraulic oils, fluid drive oils, gear oils, transformer oils, hydraulic oils of low pour point, NC machine hydraulic oils, special hydraulic oils and internal-combustion engine oils and so on. |

Product Characteristics |
||||||||||||||||||||||||
SCR-178A has a narrow molecular weight distribution and a stable structure. It offers high shear stability and excellent low temperature fluidity, efficient in improving viscosity index and inhibiting wax crystallization. This formula also offers excellent depressant effect for hydrogenarated base oil. Excellent filterability and demulsibility. |
