SR-280
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
