Titanium Dioxide for Rubber

The addition of titanium dioxide to rubber indeed enhances its performance. Specifically, the incorporation of titanium dioxide improves rubber properties in the following aspects:

1. Enhanced antibacterial properties: By adding a certain proportion of nano titanium dioxide, the antibacterial performance of rubber can be significantly improved.

2. Improved radiation resistance: Compared to unmodified rubber, silicone rubber with nano titanium dioxide exhibits reduced surface darkening and crack damage after exposure to proton irradiation of the same energy and dosage. Additionally, the extent of mass loss rate increase, thermal resistance decline, and changes in shrinkage and expansion rates are also reduced, demonstrating notable radiation resistance.

3. Improved mechanical properties: The addition of nano titanium dioxide can enhance the mechanical properties of rubber, including a significant increase in tensile strength and tear resistance. Furthermore, the heat resistance of rubber is also improved. Experimental data also indicate that after adding nanoparticles, the swelling ratio of rubber decreases, while the gel mass fraction and crosslinking density increase.

4. Increased hardness and strength: As a reinforcing agent, titanium dioxide can effectively increase the hardness and strength of rubber. This is attributed to its fine particle size and high specific surface area, allowing titanium dioxide to distribute uniformly within the rubber matrix and form an effective reinforcement network. This not only improves the wear resistance, aging resistance, and weather resistance of rubber but also extends the service life of rubber products.

5. Enhanced stability: Titanium dioxide can also act as a stabilizer, improving the stability of rubber under various conditions. Its high specific surface area enables stronger interactions between titanium dioxide and the rubber matrix, helping to inhibit discoloration, hardening, and cracking during use.

6. Improved UV resistance: Due to its excellent barrier properties, titanium dioxide can effectively prevent damage from ultraviolet rays. Adding titanium dioxide to rubber significantly enhances its UV resistance, making it safer and more reliable for outdoor applications.

Incorporating titanium dioxide into rubber significantly enhances multiple properties, including antibacterial performance, radiation resistance, mechanical properties, hardness and strength, stability, and UV resistance. These improvements broaden the application prospects of titanium dioxide-enhanced rubber in various fields.
