Which is better, red titanium dioxide or blue titanium dioxide?

Blue titanium dioxide is much more good.

Titanium dioxide production is divided into primary products and finished products. The process of domestic titanium dioxide and imported titanium dioxide is different, so there are differences in particle size and bottom phase in primary products. The imported titanium dioxide particle size distribution is uniform, and the bottom phase is blue, which is of course better.

Recommand products from TDD:
