When combined, mica and titanium dioxide in shampoo can create a synergistic effect, enhancing each other's benefits
Another top titanium dioxide manufacturer has earned a reputation for its focus on sustainability and environmental responsibility
The evidence also suggests that the toxicity of TiO2 particles may be reduced when eaten as part of the diet. This is because proteins and other molecules in a person's diet can bind to the TiO2 particles. This binding alters the physical and chemical properties of the particles, which influences how they interact with cells, tissues and organs.

These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
Oil seals can show good sealing performance in combination with properly designed shafts and housings.
- 3. Aerospace Industry Metal-to-oil seals are critical components in aircraft engines, landing gear systems, and hydraulic systems to maintain the integrity of fluids under high pressure and temperature conditions.
- In the world of agricultural machinery, the rotavator plays a pivotal role in soil preparation, ensuring optimal conditions for seed germination and plant growth. A key component that keeps this machinery functioning smoothly is the rotavator oil seal. This article delves into the significance of these seals and their role in maintaining the efficiency and longevity of the equipment.

- Another important consideration is the compatibility of the main bearing oil seal with the engine's oil. The seal must be designed to withstand the chemical properties of the oil, such as its viscosity and additives, without deteriorating. Using the wrong type of oil can cause the seal to fail prematurely. Therefore, it is essential to use the recommended oil type for your engine to ensure the longevity and reliability of the main bearing oil seal.


Stuff clean rags into the cylinder bores and all water and oil passages and bolt holes to catch scrapings and dirt.

Silicone (VMQ) Oil Seals
There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.
The depth of the bonded seal can be less and the space between the bore and the outside diameter can be changed for ease of fitting. The bonding of rubber to metal is an important factor to be considered in the manufacture of such seals and should be considered carefully, since failure of the bond will cause the seal to fail. The metal case of the oil seal is usually made from mild steel of deep drawing quality which enables blanking, punching, stamping of the steel to the required dimensions.
