Adhesives are either natural or synthetic and come in three different types: acrylic-based, silicone-based and rubber-based. Butyl tape is a synthetic rubber adhesive manufactured to upgrade natural rubber adhesives. Compared with its natural counterpart, butyl tape is less sensitive to varying temperatures and maintains its stickiness at lower temperatures than traditional rubber adhesives.

Titanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent. In lotions and creams (dermal exposure), it is not a risk for adverse health effects. However, when titanium dioxide is inhalable—as it may be when in powder form—it is considered a possible carcinogen by the International Agency for Research on Cancer.Titanium dioxide nanoparticles do not appear to confer any unique health hazards.
Historically, the first mentions of zinc sulfide being utilized as a pigment were approximately sixty years before the everyday use of lithopone. Originally, it was thought to be appropriate for coloring rubber. In England, a patent was granted for this process. Two decades after this, the focus shifted to zinc sulfide as a suitable pigment for paint. The year 1874 witnessed the patenting of a manufacturing process for a novel white pigment composed of zinc sulfide and barium sulfate. Dubbed Charlton white or Orr’s white enamel, this began a new era for white pigments.
The manufacturing process of high-quality Rutile Titanium Dioxide in specialized factories is a complex and precise operation. These factories employ cutting-edge technology and rigorous quality control measures to ensure the optimal purity and performance of the final product. The process typically involves mining, chemical treatment, calcination, and finally, crystal formation. Each step is crucial in determining the whiteness, opacity, and durability of the TiO2.
Quality is undoubtedly the most crucial factor when it comes to selecting TiO2 powder suppliers. The material should meet international standards, such as ASTM or ISO certifications, to ensure its purity, particle size distribution, and other physical properties. It is also essential to conduct thorough testing of the TiO2 powder to confirm its compliance with these standards.
A legal additive in the United States, titanium dioxide is used in everything from food to consumer goods and the U.S. Food and Drug Administration says regulated use of the product as a color additive in food is safe within certain restrictions.
