2.抗氧化性，在空气，水和铜存在的条件下，仍能够保持的抗氧化性。
涡轮机有氧化稳定性试验（TOST)结果显示得力士具有出色的抗氧化能力，酸性低，油泥生成少，因此，适用得力士可延长油品换油期，降低维护成本。
3.水解稳定性，在潮湿环境下，得力士S2 M具有超群的化学稳定性，确保了长使用寿命，避免了腐蚀和锈蚀的发生。
4.杰出的抗磨损性能，高质量的抗磨损添加剂在整个油品使用期内各种运行条件下都发挥可靠的效能，包括低负载和极端负荷的工况。
杰出的抗磨损性能在各种活塞和叶片泵试验中得到验证，包括严苛的丹尼森（Denison)T6C(干和湿环境下）及严格的威克士（Vickers)35VQ25试验。
5.出众的过滤性能，得力士S2 M液压油适合于超细滤清器，不会受水和钙等污染物的影响，上述污染物是造成超细过滤阻塞的主要原因。
用户可以使用更细的过滤器，意味着可以使用更清洁的液压油以延长设备寿命。
6.低摩擦性，得力士S2 M拥有高润滑性能和极低的摩擦，无论液压系统高速或低速运行。
在苛刻工况下也能避免粘滑问题出现，实现更精细的机械控制。
7.出色的空气释放和抗泡性能，精心选择的添加剂确保空气迅速释放，并且不会产生过多泡沫。
快速的空气释放能力可大大降低气穴腐蚀和氧化，保持系统和液压油工作可靠。
8.分水性强，避免形成油包水乳化，从而保护系统和泵，防止其损坏。
Performance characteristics:1. Thermal stability, Dex S2M hydraulic oil has a strong anti-decomposition and anti-sludge generation ability, which greatly improves the reliability and cleanliness of the system.
2. Antioxidation, in the presence of air, water and copper, can still maintain excellent antioxidant properties. The results of the oxidation stability test(TOST) of the turbine show that Delex has excellent antioxidant ability, low acidity, and low oil sludge production. Therefore, Delex can extend the oil conversion period and reduce maintenance costs.
3. Hydrolysis stability, in a humid environment, Dex S2M has superior chemical stability, ensuring a long service life, avoiding corrosion and corrosion.
4. Excellent wear resistance performance, high-quality wear resistance additives in the entire operating conditions of the oil products under a variety of reliable performance, including low load and extreme load conditions. Outstanding wear resistance has been demonstrated in a variety of piston and blade pump tests, including the harsh Denison T6C(in dry and wet environments) and the strict Vickers 35 VQ25 test.
5. Outstanding filtration performance, Dex S2M hydraulic oil suitable for ultra-fine filters, will not be affected by pollutants such as water and calcium, the above pollutants are the main cause of ultra-fine filtration obstruction. Users can use finer filters, meaning cleaner hydraulic fluids can be used to extend the life of the device.
6. Low friction, Delos S2M has high lubrication performance and extremely low friction, regardless of whether the hydraulic system runs at high or low speed. Sticky slip problems can also be avoided under harsh working conditions to achieve finer mechanical control.
7. Excellent air release and bubble resistance, carefully selected additives ensure that air is released quickly and does not produce too much foam. Rapid air release can greatly reduce cavitation corrosion and oxidation, and keep the system and hydraulic oil working reliably.
8. Water separation is strong, to avoid the formation of oil emulsion, so as to protect the system and pump, to prevent its damage.
