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是一種剪切穩(wěn)定的聚脲基潤滑脂具有優(yōu)異的極壓（EP）和承載特性。專有的聚脲增稠劑體系表現(xiàn)出優(yōu)良的耐氧化和油分離，在高的工作溫度為350°F。美孚寶力達EP 2隨著其優(yōu)秀的高溫氧化穩(wěn)定性，承載能力，剪切穩(wěn)定性，耐水性和工作溫度范圍寬，是一個優(yōu)秀的多用途潤滑脂，適用于廣泛的工業(yè)和建筑應(yīng)用。

特點和優(yōu)點

極端壓力保護及熱穩(wěn)定性

美孚寶力達EP 2包含一個專有的極壓（EP）添加劑包，提供了承載能力不降低潤滑脂在高溫下的熱穩(wěn)定性。常規(guī)的含硫和磷基抗極壓添加劑，使用在其他多用途潤滑脂開始迅速氧化在溫度高于250°F。美孚寶力達EP 2，另一方面，繼續(xù)提供高水平的抗磨和極壓保護到350°F無快速氧化的抗磨損或EP添加劑。

美孚寶力達EP 2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，高溫潤滑壽命的3?5倍優(yōu)于競爭多通用鋰基潤滑脂。

精湛的剪切穩(wěn)定性

美孚寶力達EP 2專有的聚脲增稠劑體系中顯示出優(yōu)異的耐久性和穩(wěn)定性時，受到機械剪切力。例如，在ASTM D 217圓錐貫入試驗，約一NLGI級后，被工作了10萬招 - 高品質(zhì)的復合鋰基潤滑脂的性能相似，這是基準的一致性美孚寶力達EP 2改變優(yōu)良的剪切穩(wěn)定性。與此相反，有競爭力的聚脲潤滑脂含有剪切不穩(wěn)定的增稠劑技術(shù)可以由三個NLGI年級軟化，在相同的試驗條件下。良好的機械剪切穩(wěn)定性在滾子軸承中的應(yīng)用是很重要的，可能導致過多的油脂軟化從軸承潤滑脂泄漏或清除。

優(yōu)異的耐水性

美孚寶力達EP 2配方增強防水聚合物，使得它形成了頑強的保護膜的應(yīng)用程序中嚴重污染水。美孚寶力達EP 2中的抗水沖洗（ASTM D 1264）和水噴霧關(guān)閉測試（ASTM D 4049）獲得了優(yōu)異的成績表明油脂的能力，留在原處，即使是在存在的壓水噴霧。

綜上所述，美孚寶力達EP 2提供了以下特點和優(yōu)勢：

杰出的高溫氧化穩(wěn)定性
優(yōu)良的機械剪切穩(wěn)定性
熱穩(wěn)定的極壓（EP）保護
寬工作溫度范圍（-40°F至350°F）
優(yōu)異的抗水噴霧關(guān)閉和抗水沖洗

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.

Health and Safety

Healthy skin condition depends on cleanliness. Oils and greases in contact with skin can result in plugging of sweat glands and hair follicles. This may lead to skin irritation or dermatitis. Accordingly, protective gloves, clothing and equipment should be worn and good personal hygiene should always be practiced. Oils, greases, and other foreign materials should be removed from the skin promptly. Soiled clothing should not remain in contact with the skin. Mobil Polyrex EP 2 is readily removed from the skin by waterless hand cleaners followed by washing with soap, warm water, and a skin brush. It can be removed from clothing by dry-cleaning with solvents or by washing with laundry detergents. If Mobil Polyrex EP 2 comes in contact with the eyes, flush the eyes with fresh water until the irritation subsides.

As in the case of all greases, if there is a puncture wound with grease contamination, or an injury where grease is injected into body tissue, such as a "grease gun injury," prompt medical assistance should be obtained.

WARNING: "Empty" containers retain residue (liquid and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks or other sources of ignition; they may explode and cause injury or death. Do not attempt to clean since residue is difficult to remove, and even a trace of remaining material constitutes an explosive hazard. "Empty" drums should be completely drained, properly bunged, and promptly returned to a drum reconditioner. All other containers should be disposed of in an environmentally safe manner and in accordance with governmental regulations.

Based on available information, this product is not expected to produce adverse effects on health when used for the intended application and the recommendations provided in the Material Safety Data Sheet (MSDS) are followed. MSDS's are available upon request through your sales contract office, or via the Internet. This product should not be used for purposes other than its intended use. If disposing of used product, take care to protect the environment.
