PA6 G LF - Omniamid LF
MC NYLON - blue colour - produced with the addition of solid lubricator
which gives to this product better self-lubrication. Whilst retaining
the general features of OMNIAMID LF it is more shock resistant.
FEATURES
- self-lubricating: the friction coefficient is low
- wear resistance: better than natural PA6
- tensile stress and compressive strength: same as
Omniamid G, whilst the shock resistance is higher, the fatigue resistance
is more elevated
- ageing resistance: weatherproof and good resistance
at low temperature
- blue colour
WEAK POINT
- It is hygroscopic even if to a lesser extent than natural PA6G. Because
of the molecular structure, large-sized cast pieces have better quality
than those of small dimensions.
APPLICATION
- mechanical: the best self - lubrication makes this
kind of MC nylon particularly suitable to obtain mechanical pieces which
are resistant and have a low coefficient of friction. Rispthanks to
its good mechanical features and the possibility to obtain large-sized
pieces, this material is mainly used to produce large diameter gears,
pulleys, wheels and anti-wear guides. Due to the excellent abrasion
resistance it is used in the building of parts for construction machines,
excavators and earthmovers to produce gear wheels, guide bearings, bearings,
sliding bearings etc. In the shipbuilding industry its improved weather
resistance makes it suitable for rollers, haulage, sliding guides, bearings.
In cable-car systems its uses include pulleys, wheels and sliding blocks
- food contact: it cannot be used in contact with food
- electrical: usage in the electrical field is to be
avoided as the electrical properties change with the change in moisture
content. It is sometimes used when its mechanical features are requested
- chemical: it is resistant to alkali, inorganic compounds
and solvents
