Frequently Asked Questions
Why is dioctyl sebacate selected for synthetic lubricants?
DOS provides a low pour point and high viscosity index, maintaining fluidity in extreme cold environments.
Which low-temperature pour point and flash point thresholds define dioctyl sebacate?
Target specifications focus on a pour point below -50°C and a flash point above 200°C for demanding lubricant applications.
Where is DOS evaluated outside synthetic lubricants?
It is widely evaluated as a low-temperature plasticizer in automotive cable jacketing and specialized elastomer gaskets.
