Rulon® 945 (Black) Sheet, Rod, Tube, Parts

Rulon 945 is a black PTFE material that has the lowest deformation under load of all of the Rulon grades.

It is an ideal choice for high-demand thermal applications, or anywhere excellent chemical resistance and good dimensional stability are required.

The material is best suited for use against harder mating surfaces, such as steel substrates, since it does have moderate abrasive qualities. Not recommended for applications where electrically insulating properties are necessary.

Rulon® 945 is a black material with the lowest deformation of all Rulon® grades and is suitable for use in high heat/impact applications. It is suited for use against hard mating surfaces, such as hardened steel as it has moderate abrasive properties against the mating surface.

Rulon® 945 also has very low CLTE in molded direction making it an excellent choice for high temperature bearings or seals. Best against very hard substrates.
