Ryton - Polyphenyl Sulfide
Ryton, polyphenyl sulfide, unmodified or modified with glass fibers
or other modifiers such as PTFE, MoS or graphite are used primarily
structural components. Characteristics are high stiffness, extremely
high use temperature (up to 600 degrees F), excellent chemical
resistance, and excellent electrical properties.
In both modified and unmodified forms, Ryton exhibits excellent machinability, with optical finishes possible
by grinding and lapping.
The superior friction and wear properties of Ryton make it ideally suited for bearing applications in lubricated
or non-lubricated service. Their excellent thermal and chemical
resistance properties also make Ryton very suitable in high temperature and corrosive environments.
