Lithopone pigments find extensive use in coatings, plastics, printing inks, and even cosmetics due to their excellent hiding power, light stability, and heat resistance. They serve as cost-effective alternatives to titanium dioxide, another widely used white pigment, while offering comparable performance qualities They serve as cost-effective alternatives to titanium dioxide, another widely used white pigment, while offering comparable performance qualities

3. Seal types and numbering system
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
This represents a new generation of oil seals.


Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.
