This special molecular design builds a strong chemical bridge between talc powder and carrier resin.
In the preparation and application process of talc powder masterbatch, titanate coupling agents play a key role through three core technical mechanisms:
Chemical bonding modification mechanism:
By forming coordination bonds between titanium ester groups and active sites on the surface of talc powder, deep chemical modification of the talc powder surface is achieved;
Interface compatibility optimization mechanism:
Forming a uniform organic coating layer on the surface of talc particles, significantly improving the interface compatibility between talc powder and carrier resin;
Dispersion stability enhancement mechanism:
Reduces the surface energy of talc powder, effectively preventing its aggregation and precipitation during the preparation and storage of masterbatch.
