lithopone supplier 30% applied in masterbatch has maximum purity, good opacity and reasonable light fastness.
All food businesses currently using titanium dioxide as a food additive have a legal responsibility to comply with the requirements of Regulation (EU) 2022/63, banning the use of titanium dioxide. The FSAI encourages food businesses to source suitable alternatives to titanium dioxide and start the process of reformulation now to ensure compliance in advance of the ban coming into force on 7 August 2022.
The brands of lithopone of the normal class, that of chemical manufacture, are marketed under such names as Ponolith, Beckton White, Jersey Lily White, Oleum White, Zinc Sulphide White, all of these being of domestic manufacture, and their composition is of the 30 per cent. zinc sulphide type. The German manufacturers and exporters of lithopone make use of fancy names for their brands and here are a few examples of these and the composition of the pigment:-
The principal natural source of titanium dioxide is mined ilmenite ore, which contains 45-60 percent TiO2. From this, or an enriched derivative (known as titanium slag), pure TiO2 can be produced using the sulphate or chloride process.
The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.
Titanium is a common metal element frequently found throughout nature. In our environment, titanium is naturally exposed to oxygen, forming titanium oxides that we find in many minerals, dusts, sands, and soils.

When installing a 38x52x7 oil seal, it is important to ensure that the seal is properly lubricated and aligned with the shaft. This will help to minimize friction and wear, and extend the life of the seal. It is also important to regularly inspect the seal for any signs of damage or wear, and replace it if necessary to prevent oil leakage.
It is crucial to understand that oil seals, like any other mechanical component, are subject to failure over time. The key to minimizing downtime and enhancing operational efficiency is recognizing the signs of oil seal failure and understanding its reasons. Here are some common failure modes:
Despite being incredibly flexible, silicone has some significant drawbacks. The toughness, resistance to wear, and abrasion of many silicone compounds are poor. If you seriously need an oil seal material with better strength and resistance to high temperature, the perfect option is Viton.
One of the key benefits of floating oil seals is their ability to provide a secure and reliable seal even in high-pressure environments. Unlike traditional seals that rely on compression to create a seal, floating oil seals utilize a unique design that allows them to float on the oil and adjust their position as needed to maintain an effective seal. This design not only enhances the reliability of the seal but also helps to prolong the lifespan of the seal by reducing wear and tear.

Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.
