BASF Performance Products Ultraform acetal copolymer applications have been extended to household and kitchenware such as cof-feemaker housings because of the copolymer s moldability and resistance to the acids, essential oils, fats, and more than 700 different aromatic chemicals to which the copolymer is exposed [9]. 

Polyacetals prepared from formaldehyde are engineering thermoplastics, which have found use in traditional metal applications. Some trade names of these polymers are Delrin acetal homopolymer (DuPont) Celcon acetal copolymer (Celanese/Hoechst) Duracon acetal copolymer (Celanese and Diacel—joint venture) Tenac acetal homopolymer by Asahi Chemical in Japan and Ultraform acetal copolymer jointly by BASF and Degussa, in Germany. The polymers have the basic structure shown below ... 

The first commercially available acetal resin was marketed by Du Pont in 1959 under the trade name Delrin after the equivalent of ten million pounds had been spent in research or polymers of formaldehyde. The Du Pont monopoly was unusually short lived as Celcon, as acetal copolymer produced by the Celanese Corporation, became available in small quantities in 1960. This material became commercially available in 1962 and later in the same year Farbwerke Hoechst combined with Celanese to produce similar products in Germany (Hostaform). In 1963 Celanese also combined with the Dainippon Celluloid Company of Osaka, Japan and Imperial Chemical Industries to produce acetal copolymers in Japan and Britain respectively under the trade names Duracon and Alkon (later changed to Kematal). In the early 1970s Ultraform GmbH (a joint venture of BASF and Degussa) introduced a copolymer under the name Ultraform and the Japanese company Asahi Chemical a homopolymer under the name Tenal.

Conunercial producers of acetal copolymer resins include Hoechst Celanese-Ticona (Celcon), BASF (Ultraform), Mitsubishi Gas (lupital), and LNP (Lubricomp). Only Du Pont (Delrin) and Ashai Chemical (Tenac) manufacture the homopolymer.

Acetals are produced by Asahi Chemical (homopolymer Tenac, copolymer Tenac-C, and conductive copolymer Lynex-T ), BASF (copolymer Ultraform ), DuPont (homopolymer Delrin ), Mitsubishi Gas Chemical (copolymer lupital ). Polyplastics (copolymer Duracon in Asia) and a joint venture between Ticona and Daicel Chemical Industries, Ticona/Celanese AG (copolymer Celcon and Hostaform in Europe). Mitsubishi Gas Chemical, Polyplastics, and Ticona are (jointly, directly, or through affiliates) increasing acetal production capacity in the Asia/Pacific area, with a new 60,(XX) metric ton/year plant to be completed in 2004 in Nantong, Jiangsu province, north of Shanghai. ... 

There are two main types of acetal homopolymer and copolymer. The homopolymer version was invented by DuPont in the 1950s, with the trademark name of Delrin . The copolymer version came later, under the brand names Celcon , Hostaform , Ultraform , and Duracon . The distinctions between these two versions are subtle ...
