Performance Test

Below we will show the performance comparison of phosphoric acid ester amine salt and traditional phosphoric acid ester, Here we use Shanghai Yucheng's N-5 phosphate additives for comparison

1.PB performance comparison

Extreme pressure properties in different base oils

Test method: GB/T3142

Test conditions: 0.5% additive+99.5 0N/T22/Vegetable oil

Summary: MAXEP276 showed excellent extreme pressure performance in all kinds of base oils. MAXEP017 showed excellent extreme performance in 150N, and the lubrication performance showed a downward trend in T22 and vegetable oil.

2. Long grinding performance comparison

Test scheme: 1% additive+99 0N/T22/Vegetable oil

Test method：Normal temperature environment, grinding for 60 minutes at 1200rpm/min under a pressure load of 40kgf
