Safe contact with
drinking water
Sensitive to the changes affecting the
transportation of drinking water, Lati has
been developing for some years plastic
compounds suitable for replacement of
metals such as brass in items intended
to come into contact with hot and cold
water.
In 2009, PA66 based Latigloss structural
compounds, which were introduced to
the market two years earlier, obtained
certificates of suitability for contact with
water according to WRAS (hot and cold
water), NSF 61 (hot and cold water),
ACS, KTW and W270 standards.
The success obtained by Latigloss 66
encouraged the extension of the product
portfolio intended for the specific area,
and suggested the expansion of the offer
especially with regard to contact with
hot water, a field in which polyamide 66
shows its limits.
The choice of the base resin for new
products was the aromatic polyamide
PPA, with which the compounds of
the Latigloss 57 family are formulated.
Compared to PA66, PPA provides
excellent resistance to hydrolytic and
extractive action of hot water, even in the
case of prolonged exposure over time.
In this polymer the natural moisture
absorption, which is typical of all
polyamides, is very low even at high
temperatures. This aspect allows PPA to
keep its mechanical properties as well
as item dimensions when immersed,
eliminating the risk of leaks or failure
due to the typical swelling of wet
polyamide. The compounds offered by
Lati are all inspired by the concept
of metal replacement, so they feature
structural reinforcement made of 40-60
per cent glass fibre. Eliminating metal
not only reduces costs, weight and
processing, but also avoids sources of
contamination and pollution.
As this process can only be performed
with the necessary regulatory approvals,
Lati submitted the full Latigloss 57
F2 product range with 40-60 per cent
reinforcement in the natural NAT: 0138
and black BLACK: 3302 versions to the
various certification bodies.
Results show that Latigloss 57 F2 is
best suited to contact with cold and
hot drinking water up to 85°C. This
compound combines very low residue
values and perfect behaviour with
regard to fungi and algae growth. Based
on the large number of certifications
obtained, the Latigloss 57 F2 range is a
candidate for the manufacture of valves,
mixers, baffles, tanks, taps, connecting
parts and all parts in continuous contact
with cold and hot drinking water.
Latigloss 57 F2 products can be
exported all over the world, since the
certifications allow safe use not only
throughout Europe, but also in the USA
and wherever approvals obtained are
valid. Latigloss can not only replace
metals like steel and brass, but also
more noble and expensive plastics that
are already widely used in this field, such
as amorphous and high performance
materials, eg PSU and PEI.
