The risk of production cuts is greater for car markers in the United States and France, and less in Japan and Germany, UBS said in a research note.
We see high risk of production stoppages in the second quarter, UBS analysts said in the research note issued on Thursday. But they also saw an equally high probability that alternatives would be found within the same quarter.
The global supply of PA-12, used in several industries including auto manufacturing, was already stretched thin before the explosion at an Evonik Industries AG
Auto experts and analysts are not clear how the shortfall would affect China, which has overtaken the United States as the world's largest auto market.
Florian Schattenmann, research director for Dow Automotive Systems, said Dow has allocated essential resources to find alternative solutions to the use of the nylon resin PA-12, also known as Nylon-12.
DuPont CEO Ellen Kullman, in an earnings conference call with reporters on Thursday, said the company has three polymers that could be a replacement in some automotive applications.
As the race is on to find alternative substances to the nylon resin and as automotive engineers seek work-arounds to keep making cars without PA-12, solutions likely will not be found in time to keep global auto production from falling in the second quarter, several analysts said.
Evonik is the leading maker of cyclododecatriene, or CDT, which is a base material used to make PA-12. The UBS research note said Evonik had 70 percent of the global available capacity of CDT used for the nylon resin PA-12.
Evonik made 40 percent of the world's supply of CDT, said UBS. The available supply figure is higher because some makers of CDT do not make it available to other companies to make the nylon resin PA-12, UBS said.
Two workers were killed in the March 31 blast. Evonik stopped all its production of CDT.
Evonik has said it will be at least three months and perhaps until the start of next winter before it can resume full production of CDT.
LMC Automotive said on Thursday that North American automotive production, which has been in overdrive in recent months faces a real and substantial risk of slowed output.
Automakers will be forced to more closely manage inventory and the types of vehicles they produce to cope with the looming shortage, said Jeff Schuster of LMC Automotive.
Neither LMC or UBS, nor major automakers around the world contacted by Reuters this week, have said how deeply production may be cut in the coming months.
JAPAN, GERMAN AUTOMAKERS LESS AFFECTED
Japan's automakers rely on Asia's biggest maker of PA-12, Ube Industries <4208.T> based in Yamaguchi, and German automakers can turn to Switzerland's Ems Chemie Holding
French automakers will be exposed, UBS said, because they largely rely on France's Arkema SA
U.S. automakers and suppliers are highly reliant on Evonik or companies reliant on the German industrial conglomerate to make PA-12.
Whilst the industry will likely approve substitute materials within the second quarter, the disruption to production in coming weeks may disproportionately affect automakers with already weak balance sheets, the UBS note said.
Italy's Fiat SpA
All suppliers, even those that do not make auto parts using PA-12, will be affected by the shortage, UBS said. If the shortage impacts brake and fuel systems, it will affect other components because it is difficult to assemble vehicles and fit critical parts later, the bank's analysts said.
Schattenmann of Dow Automotive said: While we do not manufacture CDT or utilize the resin made from CDT in our manufacturing processes, we are actively evaluating alternative material solutions that could replace PA-12 in select applications.
And Kullman of DuPont said: Our specialists are working on the ground with the specific (automakers) and understanding if we could provide those that it does look like we'll get some upside from that.
She said it was too early to say how deeply DuPont would become involved in the business of supplying polymers for auto suppliers and automakers, but that the effort would be positive for DuPont.
Invista Inc, a subsidiary of privately held Koch Industries of Wichita, Kansas and the maker of Stainmaster carpets, produces CDT. Invista will help the auto industry with CDT supply as much as it can, but has little to spare beyond its existing customers, said Invista spokeswoman Jodie Stutzman.
Frank Buscemi, spokesman for TI Automotive, said cooperation among automakers, suppliers and chemical companies was high.
Alternatives may not be the same for every type of auto part that uses PA-12, said Buscemi, who added that different suppliers and automakers may use different solutions to keep making the same type of tubing, hoses or fuel tanks.
