Since its introduction
in 1938, Nylon has become one of the worlds most widely recognized
and utilized engineering grade thermoplastics. Nylons unique combination
of high strength, good toughness, outstanding chemical resistance, and
excellent wear and abrasion resistance have made it the material of
choice for product designs in a multitude of industries. When used to
replace wear grade metals like brass and bronze, no other material provides
the combination of extended wear life, light weight, and low fabricated
part cost of Nylon. Nytef Plastics, Ltd. manufactures UNIPA® Nylon
stock shapes in a wide variety of types and stock shape configurations.
These UNIPA Nylon products fall into the categories of Type 6/6 Extruded
UNIPA Nylons and Type 6 UNIPA M Cast Nylons. While both types of Nylon
are very similar, there are performance and availability differences
between the two grades that should be noted:
UNIPA Type 6/6 Extruded Nylons:
offer
improved toughness
offer
improved flame resistance
are
available in smaller rod diameters (< 2" dia.)
UNIPA M Type 6 Cast
Nylons:
offer
improved wear resistance
are
available in larger rod diameters (up to 13" dia.)
are
available in larger plate sizes (up to 48" x 96")

Nytef Plastics utilizes
a proprietary nylon casting process to produce UNIPA M Nylon 6 stock
shapes. This process allows Nylon rods, plates, and tubular bars with
very thick cross sections to be economically produced with uniform physical
properties and minimal internal stress levels. Nytef Plastics
UNIPA M Nylon 6 stock shapes are available in a wide range of grades
including lubricated, heat stabilized, and fiber reinforced products.
UNIPA M Nylon 6 materials are offered in a complete range of round rod,
heavy gauge plate, and tubular bar sizes.
