Rulon 641

聚四氟乙烯

Saint Gobain Performance Plastics

 

产品说明

 

Rulon® 641 is manufactured from FDA compliant materials which possess excellent load and wear characteristics.

 

It offers excellent, continuous non-lubricated service up to 10,000 PV - higher for intermittent service. While the load capacity of Rulon 641 is generally limited to 1,000 psi at room temperature, deformation is a function of wall thickness, temperature and load.

 

Its compatibility with a wide array of mating surfaces, including mild steel, 303 and 316 stainless steels, as well as harder materials, make it a good choice for most food and pharmaceutical bearing applications.
