Tivar® Tech
Brand: 
- Self-lubricating
- Very low sliding friction coefficient
- High resistance to wear
- Satisfactory resistance to chemicals
- Highly resistant to UV radiation
Interested in this product?
This material contains molybdenum disulphide.
This solid lubricant helps further reduce resistance to sliding friction.
The friction coefficient decreases under the action of dynamic stress. It is most commonly used in sectors where very high stresses are present and dry operation is required.
Specifications:
Self-lubricating
Very low sliding friction coefficient
High resistance to wear
Long-lasting
Good resistance to chemicals
Highly resistant to UV radiation
Very good shock and noise absorption
No humidity absorption
Examples of applications: toothed and transmission wheels; sliding and drive elements; drive pulleys and supply rollers.
