The Polymethacrylate for Hydraul oil boasts outstanding performance: its polymer coils expand at high temperatures to prevent excessive viscosity loss, and contract at low temperatures to ensure fluidity.Polymethacrylate for Hydraul oil easily raises the oil’s viscosity index above 200, making it suitable for scenarios with large temperature differences between winter and summer. It also features good shear stability, with its molecular structure rarely damaged by mechanical shear, thus maintaining stable hydraulic oil viscosity and avoiding pressure instability. Additionally, it has a built-in pour point depressing effect, which inhibits wax crystallization, lowers the oil’s pour point, enables year-round use, and reduces the hassle of oil changes across seasons.
