Faber argued there hasn't been enough change in these federal regulations in the decades following the FDA's approval of titanium dioxide – especially as others increasingly point to potential health consequences.
What Is Titanium Dioxide?
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.
It’s produced through the sulfate or chloride process, which both involve treating titanium ore with sulfuric or hydrochloric acid to produce titanium sulfate or titanium chloride. These materials are then further processed to remove impurities and produce titanium dioxide in its final form.
Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
Although food-grade titanium dioxide must be 99 percent pure, there’s still a risk of it containing potential contaminants, such as mercury, lead and arsenic. Additionally, inhaling the mineral over time can possibly cause it to build up in your body, leading to adverse effects.
Uses
However, since it’s photosensitive — meaning it can stimulate free radical production — it’s usually coated in silica or alumina to prevent potential cell damage without reducing its UV-protective properties (7Trusted Source).
Among the raw materials for coating production, titanium dioxide is more ideal, followed by lithopone. The covering power of lithopone is only that of titanium dioxide, and the price of lithopone is much lower than that of titanium dioxide, so lithopone still occupies a large market share.
Hex head self-tapping bolts play a crucial role in various construction and manufacturing processes. Combining a hexagonal head design with self-tapping capabilities, these specialized fasteners are engineered for versatility and ease of use in joining materials without the need for pre-drilled holes. In this article, we will delve into the features, applications, and benefits of hex head self-tapping bolts, as well as factors to consider when using them.
Self-drilling screws, often referred to as self-tappers, are specialized fasteners that eliminate the need for pre-drilled pilot holes. They are engineered to create their own hole as they are driven into materials, making them a preferred choice for various applications in construction, manufacturing, and DIY projects. Among these, 2% self-drilling screws have gained popularity due to their unique advantages and specifications.
While steel stud bracing is an essential part of many construction projects, it is important to ensure that it is installed correctly to maximize its benefits. Proper bracing spacing, connections, and anchoring are all key factors in ensuring the stability and reliability of the structure. Working with experienced professionals who understand the importance of steel stud bracing can help ensure that your building meets all safety and performance standards.
3. Lightweight yet Strong Steel studs are lighter than traditional materials, which simplifies transportation and installation processes. Despite their lightness, they provide remarkable strength and can withstand substantial loads, making them an ideal choice for modern construction.
The versatility of 13mm self-drilling screws makes them suitable for a wide array of applications. In the construction industry, they are often used for securing metal sheets, roofing panels, and siding. Their ability to drill into hard materials without the need for pre-drilling makes them invaluable for contractors working with metal framing or installing cladding systems.

Additionally, their tool-free operation makes them an ideal choice for applications in tight spaces or hard-to-reach areas where using a conventional screwdriver might be challenging Additionally, their tool-free operation makes them an ideal choice for applications in tight spaces or hard-to-reach areas where using a conventional screwdriver might be challengingwing tek screws.2. Strength and Stability The design of countersunk screws allows for a greater surface area contact with the material, leading to a more secure fixation. This increases the overall strength and stability of the assembled components.
Why 25mm Tek Screws?
One of the primary functions of steel stud bracing is to prevent walls from bowing or buckling under load. By installing bracing at regular intervals along the length of the studs, the structure is able to distribute weight evenly and resist any potential movement or deformation. This is especially important in buildings with multiple floors or in areas prone to seismic activity, where the walls need to be able to withstand significant lateral forces.
In the construction and engineering fields, the strength and reliability of fasteners are critical. That’s why we are pleased to introduce new DIN6914/A325/A490 heavy-duty hex structural bolts to the market. This high-quality bolt is designed to provide superior strength and durability for heavy-duty applications on steel structures.
3. Corrosion Resistance Many Tek screws are coated or made from stainless steel, providing excellent resistance to corrosion. This characteristic is vital for cladding applications, especially in areas exposed to moisture and harsh weather conditions, as it extends the lifespan of both the screws and the cladding materials.
1. Variety of Sizes and Grades Hex head bolts are available in multiple sizes, lengths, and grades, making them suitable for a wide range of applications. The grading system, such as ASTM A325 or A490, denotes the tensile strength of the bolt, which is crucial for determining its load-bearing capacity.
1. Ease of Installation Drywall screws are easier to install than traditional nails, thanks to their self-tapping points. This allows for quicker and more efficient attachment of sheets.
3. Cost-Effective Compared to other anchoring systems, expanding plastic screw anchors are often more affordable. Their widespread availability in hardware stores makes them accessible for budget-conscious consumers.
