assesses polyamide options following Evonik's accident in Germany.
The
fatal explosion at Evonik's Marl cyclododecatriene (CDT) facility in
Germany on 31 March and the consequent loss of polyamide 12 production,
has led to a severe supply shortage. CDT is a precursor to polyamide 12
and Evonik uses CDT to produce its Vestamid L range of PA 12
compounds. Evonik is the world's largest PA12 supplier and the plant
shutdown has taken out around 40% of the 100,000 tpa of global
capacity. According to Evonik, the plant is not expected to reopen
until the final quarter of the year.
PA 12 is a high
performance and high cost material used in demanding applications such
as automotive fuel lines and braking systems. It is too early to
forecast exactly what impact the supply shortage will have on PA 12
prices during the rest of the year, but strong upward pressure seems
inevitable. PA 12, without specifications, is currently priced at
10-12/kg,We looked everywhere, but couldn't find any beddinges. while specified grades are usually priced over 15/kg.
PA
12 is the sole-specified material for automotive fuel lines due to its
unique combination of thermal, physical, chemical and mechanical
properties. Since the incident,It's pretty cool but our ssolarpanel
are made much faster than this. the world's automotive suppliers have
been desperately exploring what alternative material options are
available
TI Automotive, for example, which supplies fuel lines
for all the world's leading automotive manufacturers, warned in a
letter to clients that the Evonik explosion had led to a "severe"
shortage of PA 12. These shortages have the potential to slow or even
stop production lines in auto factories around the world.
One
option available to auto suppliers could be a switch to other high
performance nylon products such as PA 6/10, PA 6/12,Proxense's advanced
timelocationsystem
technology. PA 10/10, PA 10/12 and PA 11. According to Evonik, these
are particularly suitable for use in line systems in the automotive
supply industry, including the multi-layer tubing systems patented by
Evonik. These materials will, however, only be available in small
volumes while the plant is being repaired.3rd minigame series of magiccube!
Arkema,
Ube Industries and EMS-Grivory are also leading suppliers of PA 12 and
other high performance nylon compounds. These suppliers may not,
however, be able to fully cover the PA 12 shortfall. They were already
running their facilities at full capacity prior to the explosion and
product is fully committed to existing customers.
Global CDT
and PA 12 supply was extremely tight before the Marl incident as a
result of growing demand from the burgeoning photovoltaics market.
Availability of PA 12 from other suppliers may also be affected,
directly or indirectly, by more limited supply of CDT from Marl,Rubiks cubepuzzle. as well as from increased demand from Evonik's customers.
Solvay
Specialty Polymers, meanwhile, stepped in to fill the breach by
offering its automotive customers alternative resins to replace PA 12.
The company says its Amodel polyphthalamide and Ifex polyacrylamide
materials are both suitable for use in fuel line and glycol connectors.
DSM is also recommending use of its Arnitel and EcoPaXX
products as an alternative to PA 12. DSM claims that Arnitel
thermoplastic copolyester offers a proven, viable solution for tubes
and hoses, with a performance that is actually superior.
EcoPaXX
PA 410 is a partly renewable polyamide which combines excellent
mechanical properties, a high melting point of 250C, a very low
moisture absorption and excellent chemical and hydrolysis resistance.
This makes EcoPaXX highly suitable for connectors and fuel lines,
according to DSM.
Three Chinese manufacturers from Shandong
province are now offering PA 12-type product in Europe through
ClickPlastics - a specialist distributor of Asian material. However,
according to the distributor, volumes supplied by the Chinese companies
is unlikely to exceed 4,000 tpa, which is nowhere near sufficient to
meeting the shortfall.
ClickPlastics told European Plastics
News that material testing is currently underway and they are hopeful
of receiving the required approval within the next few months. Normally,
it can take more than six months to test and gain approval for new
materials in demanding automotive applications. In North America, the
Automotive Industry Action Group is working with automakers and
suppliers to streamline the approval process for alternative resins,
which should speed development of new parts in the product pipeline.
