AFA 潤滑脂是用高合成油作基油的尿素基增稠劑的高級長壽命潤滑脂

★特性

1.	長壽命潤滑脂與一般的金屬肥皂基潤滑脂不同，具有出色的氧化安定性，可長期間使用。
2.	適用溫度範圍廣泛的潤滑脂在–45℃~ +160℃的溫度範圍內，能保持良好的潤滑性。在低溫領域，表現出較低的阻力。
3.	出色的耐水性 - 水分混入對性能的影響較小。
4.	出色的機械穩定性 - 即使長期間使用，也不容易軟化的潤滑脂。

AFA Grease is a high-grade, long-life grease developed with a urea-based consistency enhancer which uses a high-grade synthetic oil as the base oil.

*Features

1.	Long life Unlike ordinary metal soap-based greases, AFA Grease exceeds in antioxidation stability and therefore can remain in service for a long time.
2.	Wide temperature range The lubricating performance remains good over a wide range of temperatures from -45 to +160 . Even at low temperatures AFA Grease requires only a low starting torque.
3.	High water resistance AFA Grease is less vulnerable to moisture contamination than other types of grease.
4.	High mechanical stability AFA Grease is not likely to soften when used for a long time.
