Overall, hub dust seals are an essential component for protecting machinery from contamination and maintaining peak performance. By investing in quality seals and ensuring they are properly installed and maintained, you can help to extend the lifespan of your equipment, reduce downtime, and improve safety in the workplace. Whether you are using machinery for industrial, agricultural, or any other applications, using hub dust seals is a smart decision that will pay off in the long run.

Oil seals are specially designed sealing devices that fit into machinery to prevent the leakage of oil and other fluids while keeping contaminants like dust, dirt, and moisture out. Typically made from elastomeric materials, they exhibit flexibility, durability, and resistance to a wide range of temperatures and aggressive chemicals. Oil seals come in various shapes and sizes, tailored to fit specific applications and installation spaces.

However, humans are not exposed to E171 in drinking water at any significant quantity over a long duration, so this potential effect is irrelevant to the human experience. It’s important to understand that a potential hazard is not the same thing as an actual risk. 

Lithopone, white powder, relative density: 4.136 ~ 4.39 g / mL, insoluble in water. It is a mixture of zinc sulfide and barium sulfate. Inorganic white pigment, widely used in plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene, and white pigments of paints and inks. It is less effective in polyurethane and amino resins and less suitable in fluoroplastics. It is also used for coloring of rubber products, paper, varnish, tarpaulin, leather, watercolor paint, paper, enamel, and the like. Used as a binder in the production of electric beads.

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.
