E2A  has  high  antioxidative  properties,is completely free of fisheye,and has a white appearance.Moreover,it  has  good  thermal stability,and in practical applications,it can improve the rigidity of the pigment and there is no odor when  melting.E291  is  recommended  for  applications  in
engineering plastics such as PA,PA glass fiber, polyester,PC and other engineering plastics; High thermal stability,low volatile content , good demoulding effect and anti-adhesion.
The pigment that is difficult to disperse or the high concentration of color masterbatch in the plastic pigment is used as the hyperdispersant. E890Ais a modified polyethylene wax that can be used in polar plastics due to  its polar groups.

It is clear from the figure that E890A can get better results in the dispersion of phthalocyanine pigment. When the strength of the pigment is unchanged,the filter pressure measured by E890A as a dispersant is much lower than that of E2A as a dispersant.In addition, the E890A has excellent lubricity and high efficiency, resulting in a lower filter pre-ssure value and a higher coloring force with a lower addition amount.
