MasterOpak

Titanium dioxide (TiO2) is the pigment traditionally used in white and colour opacifying masterbatches. This inorganic pigment is able to disperse light in an extremely efficient way, giving the materials in which it is dispersed a high opacity and whiteness. However its cost, despite being subject to constant fluctuations, is very high. This makes its replacement desirable, at least partially with alternative materials, but without jeopardizing the characteristics of the final product, namely colour, opacity, mechanical performance and stability.

The MasterOPAK project thus seeks the development of an innovative opacifying filler that allows for the partial replacement of titanium dioxide in masterbatch for thermally processed polyethylene products. This filler, consisting of hollow particles of thermosetting polymer will be developed and incorporated into masterbatch. The project focuses on a strong articulation between laboratory development and industrial validation, in order to ensure the viability of production and industrial use of the solutions found.
