Evonik offers substitutes for polyamide 12


Three weeks after the fire at its polyamide 12 feedstock plant in the Marl Chemical Park, Evonik Industries (Essen, Germany) is offering its customers various substitutes for the PA 12 resin, which will be available only in smaller volumes during plant repairs: extrusion and injection molding compounds based on PA 610, PA 612, PA 1010, and PA 1012 do not require cyclododecatriene (CDT) as a precursor.

The substitutes on offer from Evonik are particularly suitable for use in line systems in the automotive supply industry, including the multi-layer tubing systems patented by Evonik. One such substitute is the bio-based Vestamid Terra, already being used by the automotive industry.

The materials offered feature technical properties that are comparable with those of PA 12 and have similar processability. In a statement, Evonik said it "actively stands by its customers to support them in the best way possible in the selection and qualification process of the alternative materials and in minimizing the impact on supply chains."

In the present state of knowledge, the CDT plant is expected to be operational again in the fourth quarter of 2012. The regulatory authorities are still investigating the cause of the accident.-mpweditorial@ubm.com
