Xp440 sulfurized olefin extreme pressure antiwear agent has high activity and good extreme pressure performance of dialkyl pentasulfide

  Xp440 extreme pressure additive (active) Dialkyl pentasulfide , Product Overview Xp440 is a light color, almost tasteless vulcanization extreme pressure additive
It has the characteristics of high active sulfur content, good extreme pressure performance, no change in sulfur content and no precipitation during long-term storage
Xp440 has good solubility in paraffin based and naphthenic base oils, low viscosity and can be used directly without heating Expected , Use Used for cutting and forming ferrous metals, such as drilling, broaching, tapping / threading, grinding, stretching, stamping, etc It can be used in pure oil formula and emulsified / semi synthetic formula
