- Polyoxymethylene (POM),
in the USA also commonly known under DuPont's brand name Delrin, is an
engineering plastic, a polymer with the chemical formula -(-O-CH2-)n-.
It is often marketed and used as a metal substitute.
- It is also known as
polyacetal, acetal resin, polytrioxane, polyformaldehyde, and
paraformaldehyde. Polyacetals are sold under the trade names Delrin,
Kepital, Celcon, Hostaform and Ultraform[2], the last four being
copolymers.
- Polyoxymethylene (POM)
shows an ultra high modulus, a high-impact strength, stiffness,
resiliency,toughness, low friction coefficient; low gas and vapor
permeability; exceptional dimensional stability and dielectric
properties; high fatigue strength and good retention of properties at
elevated temperature.
Preparation of POM or nanohydroxyapatite
composites is done by melt processing.
- Polyoxymethylene (POM)
is a useful polymer, characterized by high crystallinity and good
mechanical properties, which is used for machine construction and as a
medical material .
- POM is manu-factured by
polymerization of formaldehyde or by copolymerization of tri-oxane and
ethylene oxide, which furnishes a more thermally stable form.
- Microscopic techniques
such as TEM and HREM are most commonly used to describe the nanoscale
dispersion of the clay in the polymer and are considered to be a tool
that provides more adequate information on the nanostructures in
comparison to X-ray diffraction methods.
- The demand for polymers
grows with the arrival of new polyacetal grades which unveil novice
applications in many areas, including medicine, sanitary, automotive
industry, and others.
- The demand for
polyacetals has been growing primarily in China.
- Currently, the car
industry consumes 40% of polyacetals, while 10 years ago there was no
single application area which dominated polyacetals consumption.
- The growth potential of
the Chinese market was cited as the primary reason that China was chosen
as the location for the new manufacturing plant.
- The current market for
polyacetal in China is estimated to be in excess of 100,000 tons per
year.
- Poly Propylene (PP)
fibers are known as effective material for the reduction in spalling.
Newly developed polyacetal fibers , which are more effective to
resistance to spalling, are being used instead of PP fibers.
