Crossflon 1801


Crossflon 1801 is black in colour and is a thermoplastic PTFE based material that is virtually 100% chemically inert except for fluorine and molten alkali metals. This material is non-ageing and possesses extremely low surface friction values when sliding against most materials. Crossflon® 1801 has been developed as an anti-static version of PTFE with similar properties to unfilled grades.
