UNITREX® Unfilled PEEK
聚醚醚酮
Nytef Plastics, Ltd.
產(chǎn)品說明:
Unitrex PEEK is a semi-crystalline
high temperature thermoplastic that offers design engineers a truly unique
combination of exceptional perbance characteristics. When compared with
other engineering polymers, this material ranks as the best or nearly the best
in every perbance category. Unitrex PEEK has a relative thermal index of 480°F and has a UL 94 flammability
rating of V-0, with very low levels of smoke generation and toxic gas emission.
Additionally, this material exhibits excellent electrical properties, which remain
stable over a wide range of both temperatures and frequencies.
Unitrex PEEK is chemically resistant to a wide range of organic and inorganic
liquids and is insoluble in all common solvents. In addition, it is unaffected
by steam and hot water and has a very low moisture absorption rate. This
material offers superior dimensional stability and machines easily. While
unfilled Unitrex PEEK offers good wear resistance, Unitrex L has been
reinforced with graphite and PTFE to provide an ideal combination of low
friction and enhanced wear. For applications that require improved strength and
stiffness, a 30% glass fiber filled grade is available (Unitrex Rg-30).
Unfilled Unitrex PEEK stock shapes are light beige in color and are available
from Nytef Plastics in a full range of heavy gauge rod, plate and tubular bar
sizes.
