JZ Polyurea Grease

Thickened by urea-base thickener,SINOPEC JZ Polyurea Grease is synthetic grease which made from specially refined mineral oil with rust and oxidation inhibitors and viscosity index improvers and other additives.According to GB/T 7631.8-90(ISO6743/9-1987),it can be classified as follow:L-XBEHA 0,L-XBEHA 1,L-XBEHA 2.

Features & Benefits

    ·  Excellent high temperature performance. Meet the lubrication requirement under comparative high temperature.

    ·  Perfect and well distributed fibre structure of its thickener provide preferable structure characteristic of grease with shear force.

    ·  Excellent dielectric stability and radiation resistant performance. Suit for special applications.

    ·  Excellent EP and anti-wear properties. Can be used at heavy load working condition.

    ·  Do not contain any heavy metal and nitrite that do harm to human’s health and pollute environment.

Technical specification

    ·  Meets the following performance specification: Q/SH303 265—2004

Application

    ·  It is suitable for lubrication cases of high temperature, heavy load, wide application temperature range and harmful dielectric-contamination conditions such as mould, arc-shaped roller bank and bending roller bearings in continuous-casting machine.

    ·  Application temperature range:-20ºCto 200ºC.
