【】 Nylon Rod 【】
Nylon rod is a generic designation for a family of synthetic polymers known generically as polyamides, first produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station. Nylon is one of the most commonly used polymers. Nylon rod is difficult to get the proportions exactly correct, and deviations can lead to chain termination at molecular weights less than a desirable 10,000 daltons (u). To overcome this problem, a crystalline, solid "nylon salt" can be formed at room temperature, using an exact 1:1 ratio of the acid and the base to neutralize each other. Heated to 285 °C (545 °F), the salt reacts to form nylon polymer. Above 20,000 daltons, it is impossible to spin the chains into yarn, so to combat this, some acetic acid is added to react with a free amine end group during polymer elongation to limit the molecular weight. In practice, and especially for 6,6, the monomers are often combined in a water solution. The water used to make the solution is evaporated under controlled conditions, and the increasing concentration of "salt" is polymerized to the final molecular weight.

♦ Nylon
Rod is an excellent engineering plastic
that is probably one of the most famous and
popular materials that since its invention has
proven its credentials as the number one all
round plastic in engineering. Over the
years has kept evolving with requirements
and advances to keep ahead of other materials.
♦ Typical Uses: Because of its
inherent properties, Nylon Rod as an engineering plastic
seems to be everywhere and able to perform a
seemingly limitless list of tasks. It is used for
bearings, bushes, pulleys, wheels, rollers, wear
guides etc. Nylon Rods is found in most modern
machinery that requires moving parts to have a
smooth, long lasting and trouble free
performance. Nylon is found in
heavy industry and manufacturing industry to help
with high load bearings and material transfer.
One key use for Nylon is for the manufacture of
gears, it is easy to machine and an excellent
resistance to wear but another important
advantage of Nylon over other materials is that
it will reduce gear noise dramatically and absorb
shock and vibration, many modern cars use Nylon
gears within their power steering systems.
Another popular use for Nylon is Nylon pulleys, this
is because Nylon can withstand
high pressure over its surface and provide a
quick and economical pulley that will last much
longer than other materials and Nylon will also
cause little damage to mating parts.
♦ Temperature Ranges:
Nylon
Rod has a working temperature
range that starts as low as -30°C up to a maximum
temperature of 100°C. This is for when the
Nylon is
being expected to resist on a constant basis, if
the Nylon is only being used at higher
temperatures on a short term basis, the Nylon can withstand
as high as 180°C, but remember this is for Nylon
being used for short time periods.
