Application advantages
Powdered Nitrile Butadiene Rubber(NBR) has good bonding effect, can increase the adhesive ability of friction material system. It can improve the impact strength of pressure embryo, and provide product flexibility. So NBR is the ideal friction material modifier, mainly used for brake pad, train brake shoe, motorcycle and other fields.
The main function and effect as following:
1.Modified phenolic resin, increase its flexibility and improve the frictional properties. To obtain high and stable coefficient of friction.
2.Add powdered NBR in friction materials make the rubber powder particles are uniformly distributed in the mixed materials, thereby reducing the abrasion of the friction material.
3.Powdered NBR has good toughening effect as the elastomer, can increase the impact strength of friction materials.
4.Low products hardness and reduce the braking noise to improve the braking comfort.
