Almost all of the vinyl building products including siding, windows, decks and fencing contain TiO2. PVC pipe for plumbing and other uses also contains TiO2. In these products, TiO2 provides protection to the vinyl by absorbing the ultraviolet (UV) rays from the sun. This prevents degradation of the vinyl, providing long lasting beauty for the lifetime of these products. You may also find TiO2 in your home flooring products. Both vinyl and laminate flooring contain TiO2.
