high pressure shaft seals
Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

20x35x7 oil seal. By sealing out these harmful particles, the oil seal helps to maintain the cleanliness and integrity of the mechanical system, prolonging its service life and reducing the need for costly repairs and replacements.
In many countries, color additives are subject to strict regulations to ensure their safety for consumption. In the United States, the Food and Drug Administration (FDA) oversees the use of color additives, requiring rigorous testing and evaluation before approval. Each additive is assigned a designation, with some being approved for food use, while others are restricted or banned due to potential health risks. Similar regulatory bodies exist in other regions, such as the European Food Safety Authority (EFSA) in the European Union.

Synthetic emulsifiers are chemically synthesized compounds that offer broader functionality and versatility compared to their natural counterparts. Common examples include mono- and diglycerides, which are often derived from glycerol and fatty acids. These synthetic emulsifiers are highly effective and are widely used in baked goods, margarine, and ice cream to improve texture and extend shelf life.
