E-glass fiber chopped strands is moistened with special sizing agent and treated by the coupling agent, so that it can ensure super caking and coalescence with all kinds of phenol-formaldehyde (PF) resins, it will form strong net-structure and inane the strength, when it is used in the frictional material.

It is mainly used for making drum brake, dist brake, short strands galss fiber clutch disk, combined brake block in railway application, short glass fiber brake band, and other frictional parts, etc.

Technical characteristics

Properties:

1. Good strand integrity, low fuzz;
2. Good flowability, good dispersion in resins;
3. Good combination with Phenol-formaldehyde resins and firm connection with boundaries;
4. High strength and good mechanical properties of the end products, it’s resistance to shock can reach up to 0.36J/c㎡
