In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”

In the realm of industrial materials, few substances command as much versatility and demand as Titanium Dioxide (TiO2) powder, particularly in its rutile form. This white pigment is not only a cornerstone in the manufacturing of paints, plastics, paper, and sunscreens but also plays a crucial role in photocatalysts and gas sensors. As a leading TiO2 powder rutile manufacturer, our factory epitomizes the confluence of cutting-edge technology and unwavering commitment to quality.

Why all of a sudden is there so much interest in the safety of Titanium Dioxide?

Researchers from France and Luxembourg gave E171 (the much more food friendly name for Titanium Dioxide) in Europe and the United States, to lab rats in their drinking water for 100 days.

Of those rats, 40 per cent of the exposed rodents developed “preneoplastic lesions” or precancerous growths. The Titanium Dioxide also inhibited the immune systems of the rats and “accelerated” the growth of the lesions. France’s INRA agricultural research institute, which took part in the study, said in a statement.“These results demonstrate a role in initiating and promoting the early stages of colorectal cancer formation,” though it said no conclusion could be drawn about later phases of cancer, or of any danger to humans……….(not till they test it on us!!)

The results of the study were published in the Nature journal Scientific Reports.

The PVC layer offers excellent protection against moisture, helping to prevent issues such as warping, mold growth, or degradation that can occur with uncoated gypsum. This makes them an ideal choice for environments with high humidity, including kitchens, bathrooms, and commercial spaces. Moreover, the robust nature of both gypsum and PVC ensures that these tiles can withstand the wear and tear of daily usage, leading to a longer lifespan compared to traditional ceiling materials.


  • Aesthetic Integration


  • The overall acoustic performance of a mineral fiber false ceiling tile is typically measured by its Noise Reduction Coefficient (NRC) rating. The NRC rating is a measure of how much sound a material can absorb, with higher ratings indicating better sound absorption. Mineral fiber ceiling tiles with a higher NRC rating can help to reduce noise levels in a room and improve the overall acoustic environment.

  • The existence of a T runner ceiling price also has implications beyond individual trading strategies. It reflects the broader economic conditions, market structure, and regulatory environment that govern financial markets. In environments where transparency and investor protection are heightened, such mechanisms may help maintain investor confidence during uncertain times.


  • One of the primary benefits of using PVC gypsum ceiling boards is their moisture resistance. In areas prone to humidity, such as kitchens and bathrooms, traditional gypsum boards can be susceptible to mold and mildew. In contrast, PVC’s water-resistant nature makes these ceiling boards an ideal choice for wet environments. Furthermore, the easy-to-clean surface of PVC allows for quick maintenance, ensuring that ceilings remain fresh and unharmed by common stains.


  • 2. Ease of Access Traditional access points may require removal of ceiling tiles or major alterations. Flush mount panels make it easy to access essential systems, allowing for quicker repairs and maintenance, which is crucial in environments where downtime can lead to significant operational losses.


  • 1. Convenience Maintenance tasks often require quick access to ceilings. Spring loaded access panels minimize disruption, allowing maintenance personnel to reach necessary utilities efficiently and without extensive time spent on setup.


  • A ceiling grid tee is a structural element used to create a framework for suspended ceilings. Typically made from metal—such as aluminum or galvanized steel—these tees form a grid that supports the ceiling tiles or panels. The “2%” in the term refers to the angle of the tee, which is designed to provide a subtle yet effective visual transition between the ceiling and the overhead systems, promoting a clean and polished appearance.


  • PVC drop ceiling grids present an excellent alternative to traditional ceiling solutions, blending practicality with style. Their durability, aesthetic versatility, and ease of installation make them a preferred choice for many builders and designers.
