Rulon XL
聚四氟乙烯
Saint Gobain Performance Plastics
產品說明
Rulon® XL is a tan colored material that is best for use against aluminum (including anodized) substrates. Rulon® XL exhibits very low wear as compared with other Rulon® grades.
Other advantages offered by this unique material are that it combines low deformation under load with exceptionally good chemical resistance.
It is compatible with a wide range of mating surfaces, but is not recommended for use with alkalis. Its non-abrasive character enhances the frictional performance to prevent galling of softer mating surfaces.
It is the best material for vacuum service.
