Not all non-stick pans use Teflon; other non-stick coatings have become available.  For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at  to produce a non-stick ceramic coating.
Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking. It is applied using a sol-gel process without the use of PFAS. The coating layer of Ceramic nonstick pans starts to break down at about 370 °C (700 °F). The coating layer of PTFE cookware starts to break down when heated to 426 °C (800 °F). 
With the EPA imposing stricter limits on the use of PFAS, some companies are voluntarily replacing their PTFE cookware with ceramic options.
