The primary function of a bottom door sealing strip is to create a barrier between the outside environment and the indoor space. This strip is typically made from materials such as rubber, silicone, or polyvinyl chloride (PVC), designed to fit snugly at the bottom of a door. Its main purpose is to seal gaps that can exist between the door and the threshold, preventing air drafts, moisture, and insects from entering the home.

- Recording Studios and Theaters In professional settings where sound quality is paramount, the use of door bottom noise seals is critical for achieving the desired acoustic environment.

A silicone door weatherstrip is a type of sealing strip made from silicone rubber, which is specifically designed to fit around the edges of doors. These strips serve as barriers against air, dust, and water, creating a tight seal that prevents outside elements from entering your home or business. The black color of the weatherstrip not only provides a sleek and modern aesthetic but also helps in blending seamlessly with most door frames.

When it comes to maintaining a clean and functional bathroom, one often-overlooked component is the shower door. Shower doors not only provide a sleek and modern look to the bathroom, but they also play a crucial role in containing water within the shower area. However, over time, the seals that line the edges of these doors can wear out, leading to annoying leaks and potential water damage. This is where adhesive shower door seals come into play, offering an effective and convenient solution to this common issue.

Because of health risks, France banned titanium dioxide as a food additive in 2020. Two years later the European Union also banned titanium dioxide as a food additive. 

People eating lots of candy should be more worried about the sugar and how it can cause high blood pressure and obesity, says Westerhoff.

Australian researchers examined how titanium dioxide as a food additive affected gut microbiota in mice by orally administering it in drinking water. The study, published in the journal Frontiers in Nutrition in 2019, found the treatment could “alter the release of bacterial metabolites in vivo and affect the spatial distribution of commensal bacteria in vitro by promoting biofilm formation. We also found reduced expression of the colonic mucin 2 gene, a key component of the intestinal mucus layer, and increased expression of the beta defensin gene, indicating that titanium dioxide significantly impacts gut homeostasis.” The changes were then linked to colonic inflammation, along with a higher expression of inflammatory cytokines, which are signal proteins that help with regulation. The researchers concluded that titanium dioxide “impairs gut homeostasis which may in turn prime the host for disease development.”

This work confirms previous studies that show P-25 and other untreated anatase 377 nanoparticles should not be employed in sunscreens because the toxicity of P25TiO2NPs under UV radiation is significant.
