Nano Titanium oxide

The nano-titanium dioxide for rubber is white fluffy powder. After special surface organic modification, it has better dispersibility in rubber. Most nano-titanium dioxide particles have a size of less than 80nm in rubber, which greatly exerts nano-materials characteristics.

Applications:

1. Add 2.0% nano-titanium dioxide (DK-TiO2-TX30A) to rubber, the best antibacterial performance, the inhibition rate can reach more than 85%.

2. Compared with unmodified rubber, the silicone rubber with nano-titanium dioxide (DK-TiO2-TX30A) has a reduced surface color and surface crack damage after the same energy and dose of proton irradiation; the mass loss rate increases. The degree of change in heat resistance and the degree of change in shrinkage expansion ratio are all reduced, showing significant anti-irradiation properties, greatly improving the anti-aging properties of rubber.

3. Nano-titanium dioxide (DK-TiO2-TX30A) can improve the mechanical properties of rubber, and the tensile strength and tear strength are obviously improved, and the heat resistance of rubber is also improved. Swelling experiments show that after the addition of nanoparticles, the swelling ratio of the rubber decreases, and the gel mass fraction and crosslink density increase.

  Add amount: recommended addition amount 1-5%.
