The effect of pigmentation on the mechanical properties and the crystallisation behaviour of polymer blends (Xenoy®)

Several techniques have been used to study the effect of C.I. Pigment Blue 15:4 and C.I. Pigment Red 122 on the properties of a pigmented Xenoy® blend. The pigments were incorporated into the blend during extrusion. Both pigments acted as nucleating agents, increasing the crystallinity of the pigmented Xenoy® compared to that of the unpigmented blend. Of the two pigments studied, C.I. Pigment Red 122 has a greater effect on the properties than occurs with C.I. Pigment Blue 15:4.
