Nylon 66.6
- Akulon GX
Copolymer of
nylon with excellent mechanical features, it combines the good impact
resistances of PA6 as well as the higher stiffness of PA66. For this reason it
machines very well on automatic tools and on CNC centres. The U.V. stabilisation
makes it light resistant and it is therefore suitable for outdoor applications.
FEATURES
Wear resistance: good
even in demanding environments.
Toughness: high tensile stress and compressive strength.
Self-lubricating: the friction coefficient is low and generally for sliding
application it does not require lubricators.
U.V. resistance:
particularly suitable for outdoor applications it withstands atmospheric agents
and low temperatures very well.
Machining on automatic
tools is easy thanks to the breaking of shavings during machining and to its
higher stiffness.
Black colour.
WEAK POINT
It is hygroscopic (even if at lower extent than
PA6) therefore the mechanical features and the dimensions will change
consequently
APPLICATION
Mechanical: thanks to its higher stiffness compared to PA6 and its higher
shock resistance compared to PA66, this material is increasingly being used in
the mechanical field to produce gears, cams, pulleys, anti-wear guides, wheels
and other components, notably for outdoor use. In the field of construction and
earthmoving equipment Akulon GX can be found in guides, bearings and pulleys. it
is particularly suitable for machining on automatic lathes.
Food contact: generally it is not used in contact with food.
Electrical: use in the electrical field is to be avoided as the
electrical features change with the moisture content. It is sometimes used when
its mechanical features are required.
Chemical: it is resistant to alkali, inorganic compounds and solvents
