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:
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.
