When discussing about tio2 application in rubber, firstly, you need to know what is rubber?
Rubber is an organic polymer compound that is classified into natural rubber and synthetic rubber depending on the source. Their common feature is high elasticity. In addition, it has excellent properties such as imperviousness, airtightness, and insulation.
What are the applications of rubber?
Because of its properties, rubber has a wide range of applications, regardless of industry, agriculture, transportation, national defense, and people’s daily lives.
How to make better rubber?
In the rubber industry, in order to improve the performance of the raw rubber in the process and the performance of the vulcanized rubber, it is necessary to add a vulcanizer, an accelerator, an active agent, an antioxidant, a reinforcing agent and a coloring agent, or a dozen or so kinds of assistance.
What is the import role of titanium dioxide(tio2) in rubber.
The agent makes the rubber materialized and chemically changed. Titanium dioxide(tio2) is a good coloring agent because of its stable physical and chemical properties, small particles, and no impurities such as manganese, copper, cadmium and cobalt in the vulcanization process, which will not damage the vulcanization process due to its colorlessness and High hiding power, the use of a small amount of titanium dioxide(tio2) can achieve the best coloring effect, but has no effect on the tensile strength, elongation and bending properties of the product.
At the same time, the anti-sun property is extremely strong, and it does not crack under the sunlight and does not change color. Therefore, titanium white powder is generally indispensable in white and light-colored rubber products.
What are the characteristics of tio2-contained rubber?
The rubber product made of titanium dioxide has the characteristics of slow aging, high strength, large elongation, and difficulty in fading. In addition, it has a filling, anti-aging, acid and alkali resistance and reinforcing in silicone rubber. Therefore, titanium dioxide is indispensable in the rubber industry.
What are the qualities of titanium dioxide(tio2) for rubber?
The quality of titanium dioxide for rubber has the following requirements:
1. Good heat resistance, vulcanization at 110~170 °C without yellowing.
2. Good stability to sulfur and other additives.
3. High color and hiding power
4. There should be no adverse effects on the properties of rubber products (such as physical properties, mechanical properties, and aging properties).
5. Less harmful impurities such as copper, manganese, cadmium, and cobalt6. The particles are small and easy to disperse uniformly.
