PEEK is a kind of heat-resistant, high performance thermoplastic
special engineering plastics. It has good mechanical
properties and chemical resistance, abrasion resistance, and
hydrolysis resistance properties etc.; it has a light proportion
and self-lubricating properties.

PEEK, can be used to produce all kinds of parts in the planes
instead of aluminium and other metals.
With its excellent flame retardant, the inner parts, made of PEEK,
can reduce the damage degree of fire in the planes.
PEEK has successfully test in Chinese "Shenzhou" Spaceships series
and widely applied in Boeing and Airbus airliner
at present.


Product performance
Heat-resistance
PEEK has a higher glass transition temperature and melting point
(334ºC). It is one of the reasons that it can be a reliable
application in the requirement of the heat. Its heat load
variable-temperature can be 316ºC, continuous use temperature
is 260ºC.
Self-lubricating
PEEK has outstanding sliding characteristics in all plastics; it is
suitable for stringent requirements for low coefficient of
friction and resistance to friction used. Especially, the
self-lubricating properties of PEEK will be better if it is
modified by
carbon fiber and graphite mixed in the proportion of each of them.
Fatigue Resistance
PEEK has the best fatigue resistance among all resins.
Hydrolysis Resistance
PEEK and its composites will not be affected chemically by water
and high-pressure steam. The products that are made
from this material will maintain the outstanding characteristics in
continuous use in high temperature and high pressure
water.
