美孚寶力達EP 2
多用途潤滑脂
產(chǎn)品描述
美孚寶力達EP 2是剪切穩(wěn)定的聚脲潤滑脂具有優(yōu)良的極壓(EP)和承載特性牛欢。專有的聚脲增稠劑體系具有優(yōu)異的耐氧化性和油分離在操作溫度高達350°F。憑借其出色的高溫氧化穩(wěn)定性躺苦,承載能力強榛架,剪切穩(wěn)定性拯钻,耐水性和較寬的工作溫度范圍內(nèi)途陵,美孚寶力達EP 2是一個優(yōu)秀的多用途潤滑脂掸阶,適用于工業(yè)和建筑應用廣泛墩沸。
特點和優(yōu)點
極壓保護和熱穩(wěn)定性
美孚寶力達EP 2包含一個專有的極壓(EP)添加劑包蚣枝,提供了承載能力而不在高溫下降低了潤滑脂的熱穩(wěn)定性。在其它多用途使用的常規(guī)硫和磷的基極壓添加劑的潤滑脂開始在溫度高于250°F址嘴。迅速氧化 美孚寶力達EP 2歼呼,另一方面,繼續(xù)提供磨損和極壓防護蚀弹,高水平至350°F無抗磨損或抗極壓添加劑的快速氧化犁捕。
美孚寶力達EP 2的出色的高溫潤滑壽命赫然展現(xiàn)在ASTM D 3336潤滑脂壽命測試 - 平均ASTM D 3336壽命為490小時,3?5倍以上的有競爭力的多高溫潤滑生活更美好目的鋰基潤滑脂减叫。
濠江剪切穩(wěn)定性
專有的聚脲增稠劑體系在美孚寶力達EP時萤遥,受到機械剪切力2顯示出優(yōu)異的耐久性和穩(wěn)定性。類似的高品質(zhì)的復合鋰基潤滑脂的性能包竹,這是基準 - 例如燕酷,在ASTM D 217靜力觸探,美孚寶力達EP 2的一致性了大約一個NLGI級正在制訂100,000中風后改變優(yōu)良的剪切穩(wěn)定性周瞎。與此相反苗缩,含有剪切不穩(wěn)定增稠劑技術(shù)競爭的聚脲潤滑脂可以在相同的測試條件下,通過3 NLGI等級軟化声诸。良好的機械剪切穩(wěn)定性是很重要的滾子軸承應用中過多的油脂軟化可能導致從軸承潤滑脂的泄漏或清洗酱讶。

Mobil Polyrex EP 2
Multi-purpose Grease
Product Description
Mobil Polyrex EP 2 is a shear-stable polyurea grease with excellent extreme-pressure (EP) and load-carrying characteristics. The proprietary polyurea thickener system exhibits excellent resistance to oxidation and oil separation at operating temperatures as high as 350°F. With its outstanding high-temperature oxidation stability, load-carrying capability, shear stability, water resistance and wide operating temperature range, Mobil Polyrex EP 2 is an excellent multi-purpose grease for a wide array of industrial and construction applications.
Features and Benefits
EXTREME-PRESSURE PROTECTION AND THERMAL STABILITY
Mobil Polyrex EP 2 contains a proprietary extreme-pressure (EP) additive package that provides load-carrying capability without degrading the thermal stability of the grease at high temperatures. Conventional sulfur- and phosphorus-base EP additives used in other multi-purpose greases begin to oxidize rapidly at temperatures above 250°F. Mobil Polyrex EP 2, on the other hand, continues to provide a high level of wear and extreme-pressure protection up to 350°F without rapid oxidation of the anti-wear or EP additives.
The outstanding high temperature lubrication life of Mobil Polyrex EP 2 is impressively demonstrated in the ASTM D 3336 grease life test - with an average ASTM D 3336 life of 490 hours, 3 to 5 times better than the high-temperature lubrication life of competitive multi-purpose lithium-base greases.
SUPERB SHEAR STABILITY
The proprietary polyurea thickener system in Mobil Polyrex EP 2 exhibits excellent durability and stability when subjected to a mechanical shearing force. For example, in the ASTM D 217 cone penetration test, the consistency of Mobil Polyrex EP 2 changed by approximately one NLGI grade after being worked for 100,000 strokes - similar to the performance of high-quality lithium-complex greases, which are the benchmark for excellent shear stability. By contrast, competitive polyurea greases containing shear-unstable thickener technology can soften by three NLGI grades under the same test conditions. Good mechanical shear stability is important in roller bearing applications where excessive grease softening may lead to grease leakage or purging from the bearing.
EXCELLENT WATER RESISTANCE
The Mobil Polyrex EP 2 formulation is enhanced with water-resistant polymers that enable it to form a tenacious protective film in applications that are heavily contaminated with water. The excellent results obtained for Mobil Polyrex EP 2 in the water washout (ASTM D 1264) and water spray-off (ASTM D 4049) tests demonstrate the grease's ability to stay in place, even in the presence of a pressurized water spray.
In summary, Mobil Polyrex EP 2 offers the following features and benefits:
- Outstanding high-temperature oxidation stability
- Excellent mechanical shear stability
- Thermally stable extreme-pressure (EP) protection
- Wide operating temperature range (-40 F to 350 F)
- Exceptional resistance to water spray-off and water washout
Applications
Mobil Polyrex EP 2 is an excellent multi-purpose grease for a wide array of industrial and construction applications.
