Nylacast Cast Nylon 6
Cast Nylons are a range of polyamides produced by a
casting process involving the anionic polymerisation of
caprolactam. This process allows the production of semi-
finished plate, rod, tube and custom castings that are largely
free of internal stresses. Natural cast nylon (available also
in black) is the basic cast nylon 6 grade and the one from
which all the other grades of cast nylon stem. Generally
accepted as the primary engineering polymer, natural cast
nylon is suitable for virtually any plain bearing application,
not to mention a huge range of other applications for which
this versatile grade finds a use. By varying the conditions of
polymerisation the mechanical properties of cast nylon may
be altered to suit specific applications and the performance
of the basic polymer can be enhanced with the addition
of various additives, fillers, lubricants and colorants (see
further grades).
Compared with injection moulding and extrusion grades
of polyamide, cast nylons stand out with their improved
mechanical, thermal and chemical resistance properties.
Specifically the material has a higher tensile, compressive
and impact strength as well as an improved resistance to
creep and heat ageing. The reasons for these improved
characteristics are high crystalinity and a remarkably higher
molecular weight. Due to low water absorption, mechanical
properties and dimensions are more stable making it suited
for components that have to meet closer tolerances.
Abrasion resistance and overall wear performance are
probably the materials most important characteristics for
use in bearing applications and in applications where food
contact is involved, cast nylons may be offered as a material
conforming to FDA approvals.
Natural cast nylon has the ability to operate effectively
without the need for lubricants and has an increased
resistance to wear of over 5 times that for plain bearings
manufactured from non-ferrous metals. As is the case
with virtually all nylons it is easy to machine, pleasant to
work with and relatively light weight - one eighth that of
brass - making the handling and fitting of large components
manufactured in cast nylon a relatively easy matter.
