产品详细介绍
POM FU2025三菱POM was developed by DuPont in the late 1950s and is
one of the three most common engineering plastics in the world. POM
has metal hardness, strength and steel, excellent fatigue
resistance, elasticity, POM also has good chemical resistance. POM
has been widely used in electrical, mechanical, instrumentation,
daily light industry, automobile, building materials, agriculture
and other fields since its production. Because the cost of POM is
lower than that of other engineering plastics, it replaces the
market occupied by metals, and shows a good growth trend in new
application fields, such as medical technology, sports equipment
and so on.
POM has regular molecular structure, high crystallinity and high
surface hardness. In the process of friction and sliding, its
macromolecule is easy to be oriented and strengthened along the
direction of friction, with large bond energy and high molecular
cohesion energy, so POM has good wear resistance and
self-lubrication performance. However, it is difficult to meet the
requirements of high load, high speed, high temperature and other
working conditions, so the wear resistance of POM needs to be
further improved. There are two ways to improve the wear resistance
of POM: one is chemical modification. Lubricating segments were
introduced into POM molecular chains by means of grafting and
block. The other is physical blending modification. Duracon NW-02,
developed by Japan Plastics Company, is a lubricating modifier made
of a lubricating polymer grafted with POM. Under the same load and
sliding speed, the sliding surface temperature of Duracon NW-02 is
30%-50% lower than that of the unmodified POM.
POM has the characteristics of high hardness, wear resistance,
fatigue resistance, high impact strength, good dimensional
stability and self-lubrication. POM is widely used in manufacturing
various sliding and rotating mechanical parts, making various
gears, levers, pulleys and sprockets, especially suitable for
bearings, hot water valves, precision metering valves, chain rings
and rollers of conveyors, and flow. Gauge, internal and external
handles, cranks and other window rotating machinery, oil pump
bearing seat and impeller gas switch valve, electronic switch
parts, solid, wiring column mirror mask, fan parts, heating plate,
instrument button; bearing of audio and video tape; various
pipelines and agricultural port sprinkler systems and valves,
sprinklers, taps, taps, etc. Bath basin parts; switch keyboard,
button, audio-visual tape reel; temperature control timer; power
tools, garden realizing tool parts; in addition, can be used as
surfboard, sailboat and various sled parts, watch micro gear,
sports equipment frame accessories and backpack with various
buckles, sturdy parts, lighter, zipper, buckle ring. Heart
pacemaker of medical instrument leaf; artificial heart valve,
apical vertebra, prosthesis, etc.
The crystallinity of POM is high, generally up to 70%-85%. The
crystalline grains are large and the notch impact strength is low.
POM often breaks in brittle mode. There are two main ways to
improve the impact toughness of POM: elastomer toughening and rigid
particle toughening. Elastomer toughening POM is a traditional
toughening method. Because of the low modulus and flexibility of
rubber or thermoplastic elastomer, the shear yield and crazing of
the matrix are induced as a stress concentration system in the
plastic matrix, which promotes the brittle-ductile transition of
the matrix and improves the toughness of the material.
