VESTAMID® POLYAMID 12

THE CORNERSTONE OF EVONIK’S HIGH PERFORMANCE POLYMERS

Since more than 50 years polyamide 12 is a fundamental stone in Evonik’s product portfolio and has been the cornerstone of the future development of its high performance polymers.



Geschichte VESTAMID

VESTAMID® tubing at Ford, 1973

In 1963
at the K´63 plastics trade show, the former Chemische Werke Hüls AG unveils VESTAMID®, a polyamide 12 produced on the pilot-plant scale by a process developed in-house. Nobody could have imagined that the polymer specialty, regarded internally with some skepticism, would lay the foundation for high performance polymers from Evonik

The steps involved in the process are:

  • trimerization of butadiene

  • hydrogenation of cyclodecatriene to cyclododecane

  • oxidation of cyclododecane to cyclododecanone

  • reaction of cyclododecanone with hydroxylamine, to yield cyclododecanone oxime

  • production of laurolactam by Beckmann rearrangement, using Ziegler catalysts

1966: 
The first reactor, with an output of 1,200 metric tons of polyamide 12 per year, goes into operation. Under the brand name VESTAMID®, the product is processed into compounds, coating powders, and copolyamide hot-melt adhesives. 



The names VESTOSINT® for the polyamide 12 powders and VESTAMELT® for the copolyamide hot-melt adhesives are used for the first time at the K´86 plastics trade show. 




The development of polyamide 612 also starts in the mid-1960s.

1970: 
Chemische Werke Hüls AG and Daicel Ltd., Tokyo, establish a 50:50 joint venture, Daicel-Hüls Ltd.—now Daicel-Evonik—in Osaka, Japan, for the manufacture of polyamide 12 and its sale under the name DAIAMID in East Asia.

1977: 
Start of plant-scale trials for production of polyamide 12 elastomers. These will be marketed in the following years under the name VESTAMID® E.

2000: 
Following construction of a pilot plant, a commercial plant is commissioned for continuous production of polyamide 12. The process was developed by Evonik (former Hüls) in 1993. 

2008: 
At the FAKUMA trade show in Friedrichshafen, Evonik unveils VESTAMID® HTplus, a high-temperature-stable semicrystalline material based on polyphthalamide, to the general public 


2009:

With VESTAMID® Terra, Evonik launches polyamides of biogenic origin for the first time on the market.
