The sound-absorbing characteristics of mineral fiber ceiling boards are among their most significant benefits. These boards are designed to reduce noise levels in a space by absorbing sound waves, which limits echoes and reverberation. This makes them an ideal choice for areas such as classrooms, conference rooms, and healthcare facilities, where clear communication is essential. The Noise Reduction Coefficient (NRC) rating of these boards often falls between 0.5 to 0.9, indicating excellent sound absorption capabilities.

Is titanium dioxide (E171) harmful to our health?
-
Titanium dioxide is a versatile material with a wide range of applications. Some of its most common uses include:
- In the area of photodynamic therapy, TiO2's photocatalytic properties have sparked interest
Lithopone 30% CAS No. 1345-05-7
Titanium dioxide is often used as a UV absorber and pigment in cosmetic products, such as foundations, lipsticks, creams, sunscreens and other skin care products. It helps protect the skin from the harmful effects of UV rays by blocking them, while providing a brightening effect.
Titanium dioxide, also called titania, is an odorless white powder and naturally occurring mineral that is widely used as a pigment for its brightness and whitening effects on a variety of materials, such as paint, plastic, paper, cosmetics, sunscreens, toothpastes and foods.

Why does the exposure route matter, and what's the risk?
When used as a base or colorant in a product, titanium dioxide becomes handy in formulas meant to offer a lot of brightness and opacity. Titanium dioxide is so pigmented, in fact, that it’s used not only in white and pastel-colored products but also in darker shades, as well.
Lithopone is a mixed zinc sulfide-barium sulfate brilliant white pigment that contains about 30% zinc sulfide. The original light sensitiveness of this pigment has been mitigated by purification and by the addition of such agents as polythionates and cobalt sulfate.
Titanium Dioxide Raw Material Tio2 Powder
Overall, Chinese anatase titanium dioxide stands out as a versatile and valuable material with a wide range of applications in various industries. Its unique properties make it a popular choice for use in pigments, sunscreen, environmental remediation, and energy conversion technologies. As research into this material continues to expand, we can expect to see even more innovative uses and advancements in the field of materials science.
In order to achieve the same solids content, the larger filler and the binder should be reduced if necessary.

In addition to its strength and UV resistance, nano titanium dioxide also has excellent optical properties. This makes it an ideal material for use in pigments and coatings, as it can help create vibrant colors and enhance the appearance of a wide range of products. Our nano titanium dioxide products are carefully formulated to ensure that they provide the best possible optical properties, so customers can achieve the look they desire.

After conducting a review of all the relevant available scientific evidence, EFSA concluded that a concern for genotoxicity of TiO2 particles cannot be ruled out. Based on this concern, EFSA’s experts no longer consider titanium dioxide safe when used as a food additive. This means that an Acceptable Daily Intake (ADI ) cannot be established for E171.
Respiratory Exposure
Health Canada's Food Directorate recently completed a “state of the science” report on titanium dioxide (TiO2) as a food additive. Food-grade TiO2 is a white powder made up of small particles that has been permitted in Canada and internationally for many years as a food additive to whiten or brighten foods. Food-grade TiO2 has long been considered safe in Canada and in other countries when eaten as part of the diet.
