Cel-Span S 100 is an additive for color stabilization and dispersion. Cel-Span S 100 lessens the degradation of pigments and enhances the brightness of color concentrates. When pigment is initially dispersed in a master-batch a process of contact adhesion can cause pigment particles to form large size clusters. A dispersion aid can help separate the pigment and allow it mix evenly throughout the polymer. Additional process stabilizers can help limit the effect that additional heat histories can have on critical colors.
