Significance and Use
3.1 Titanium dioxide is used in rubber compounding as a colorant to impart whiteness to any desired end product. It is used in sidewalls of automobile tires.
3.2 It is chemically inert and slightly basic with a pH of 7.0 to 8.0. The free-chalking, weathering properties of anatase titanium-dioxide provide a (self-cleaning) white appearance in outdoor applications.
1.1 This classification covers the compounding material known as titanium dioxide. It is generally used in rubber compounds to impart whiteness to selected products. Typical chemical and physical properties are included.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
