The list above is only a partial list of available Rulon grades (formulations).

PV data may be exceeded based on specific application requirements. Ask to speak to a TriStar Application Engineer.

RATINGS above are relative within Rulon® family ONLY.

For Rulon® materials, coefficient of friction decreases with increasing load and wear decreases with increasing surface hardness.

For PTFE based materials, wear in steam and wet environments is higher than in dry environments. Saint-Gobain offers enhanced Rulon® grades which minimize this effect.

Most Rulon® products have excellent chemical compatibility. Data available upon request.
