The addition of talc in TPU/PP blends improved miscibility in all investigated TPU/T/PP blends. The DSC results for talc filled TPU/PP blends show that the degree of crystallinity increased, which is due to the nucleating effect induced by talc particles.

Paints also contain talc to enhance the adhesion of coatings to a base and to improve the bending strength of the paints. Platelike talc particles (Jubete et al., 2007) are used to formulate primers with anticorrosion properties. Specularite is another pigment with anisometric particles. It consists of platelike hematite particles αFe 2 O 3.
