After the glass fiber is reinforced, during the injection molding process, the glass fiber enters the surface of the plastic product, making the surface of the product very rough and spotty. 

In order to achieve a higher surface quality, the lubricating and dispersing agent 221 can usually be added to improve the bonding state of the glass fiber, the inorganic filler and the matrix resin. Furthermore, the dispersibility of glass fibers and inorganic fillers in the matrix resin is improved. At the same time, 221 has lubricating properties, improves the processing fluidity of composite materials, and improves the surface finish of composite materials.
