SR-280

SR-280 is a titanium dioxide pigment specially designed for applications in the plastic field with high requirements for dispersibility and bottom phase. SR-280 has better whiteness, bluer background color, higher tinting power, better dispersion and lower volatile matter. It does not add zinc compounds and has more stable quality.

Application

High grade color masterbatch, especially color masterbatch and spinning masterbatch for ultra-thin film blowing, high temperature and high speed film blowing

Plastic color matching industry

PVC sheet

PVC film

Modified plastics with blue background
