Rulon 123
聚四氟乙烯
Saint Gobain Performance Plastics
產(chǎn)品說明
Rulon® 123 is a glossy black non-abrasive compound for softer mating surfaces, such as stainless steel. This material has excellent chemical resistance and is FDA, USDA, and NSF compliant. It is less expensive than Rulon J, but is slightly less flexible and higher in wear.
It has a high resistance to deformation, low coefficient of friction and good thermal and electrostatic dissipation. This material has a maximum operating temperature of 550°F (300°C).
Rulon 123 releases black wear debris over time and should not be used in ultra-dry, vacuum applications, or where electrical insulation is desired.
