Because MC nylon and high crystallinity, and thus exhibit good cold Wear resistance. It is only in the initial use slightly worn, after the little metal products, as it does not like, wear and use of proportional growth (see Table 5,6,7,8).

M5：tdber Wear Test

M6:MC nylon filler is added in case the friction coefficient is relatively

Description: Test temperature 58 ℃, load 50kg/cm2, speed of 190 rev / min, test time 15 minutes.

M7：MC nylon lubrication conditions in different wear factor

M8：Variety of materials and PV values ​​of friction coefficient
