High Lubrication POM

The lubrication properties of POM can be improved by adding graphite, F4, molybdenum disulfide, lubricating oil and low molecular weight PE. For example, adding 5 phr F4 to POM can reduce friction coefficient by 60% and increase wear resistance by 1-2 times. Additionally, adding liquid lubricant to POM can greatly improve the wear resistance and limit PV value.  

In order to improve the dispersing effect of oil, carbon black, barium hydroxide, barium sulfate, ethylene propylene rubber and other oil-absorbing carriers should be added. The frictional property of POM with 5% oil increases by 72%, and the limit PV value can reach 3.9 MPa M / s (pure POM is 0.213 MPa M / s), which is 3-20 times as much as that of other engineering plastics.
