The growing attention to environmental
and health problems makes treatment of waste and
manipulation of heavy metals more and more complex.
Among these substances lead stands out for both
toxicity and diffusion.
However its physical features and the metal workability
make it suitable to be used on a large-scale wherever
efficient X and gamma shielding is needed, such
as in medical sector applications, in the industrial
X-ray and in the handling of radioactive sources.
In all these cases lead is fully used for the
production of plates, isolation and protection
containers providing safe working conditions to
personnel exposed to dangerous beams.
However the problem is both in the lead transformation,
in its manipulation and finally in the treatment
of waste: all these operative phases are characterized
by a significant impact on environment and human
Studying the shielding phenomenon it has been
observed that other substances have similar features
to those of lead. LATI offers a range of Thermoplastic products
suitable for injection moulding and providing
an outstanding X-ray shielding effect. LATIGRAY
compounds are produced by using fillers with
an excellent radiation stopping power: ceramics,
metal oxides, mineral fillers, eco-efficient metals
such as tungsten.
LATI Radio-Opaque products are obtained by using
PP, PA and the most advanced thermoplastic resins
such as PPS and PEEK, in order to satisfy every
design requirement even in terms of temperature
and environmental compatibility.
Thanks to injection moulding technique, LATI is
able to produce radio-shielding compounds to be
used also with mould cavities featuring special
geometries, respecting design requirements, minimizing
manufacturing waste and consequently reducing
direct and indirect costs. Moreover with LATIGRAY
compounds it is possible to have a technological
advantage and a competitive progress of the manufacts.
LATIGRAY shielding features can be optimized according
to the requirements, selecting the typology and
the quantity of radio-opaque filler added to the
LATI can thus produce X-rays opaque compounds
filled with special mineral additives and ceramics
as well as completely shielding grades as for
steel or tungsten filled products.
LATIGRAY compounds filled with tungsten can guarantee
shielding efficiencies very close to the one of
lead, providing the same protection with similar
wall thicknesses. Half Value Thickness data, indicating
material thickness necessary to half the incoming
beam, suggest tungsten filled LATIGRAY as even
more efficient than lead.
LATI Radio-opaque Thermoplastics are used
in medical X-ray devices, e.g. in the dental sector
where it is possible to produce pins, bearers
and other tools visible to fluoroscopy and X-ray
photography thanks to the excellent contrast with
Concerning X-ray photography, a LATI radio-opaque
material has been used in the dental sector through
the innovative "Drilling Security System"
developed by ARSLINE; the drilling system allows
the dentist to obtain a pre-adjusted height of
screwing in order to avoid wrong odontology operations.
New functional benefits are obtained with the
substitution of a metallic part replaced by the
LATIGRAY compound that offers its high performance
Atoxic Radio-Opaque Compounds are characterized
by easy transformation and immediate waste treatment:
with LATIGRAY Compounds heavy metals substitution
is now reality.
