  E This is the most widely used of the general synthetic fibers for brushes. It has high wear resistance, elasticity, and recovery from bending.
E It is most commonly used with neutral or weak alkaline solvents for cleaning, but its resistance to acids is poor.
E Heat resistance varies between types of nylon, but it is usable below around 80‹C
E Can handle use with abrasive particles
