Igelite

from Wikipedia, the free encyclopedia

Igelit is a formerly registered trade name for soft PVC , especially a copolymer with z. B. 20% acrylic acid ester with 80% vinyl chloride . In addition, the plasticizer tricresyl phosphate (TKP) was added in a proportion of up to 30%.

The name alludes to the owner of the naming rights, IG Farbenindustrie A.G. It was used by the successors of IG-Farben until the post-war period, but then, like other trade names with the initials IG- , had to be abandoned in the course of the liquidation of IG Farben become.

Production history

In 1938 the Bitterfeld plant started production with a monthly production of 120 tons. In the GDR , the former IG-Farbenwerke VEB Elektrochemisches Kombinat Bitterfeld and the Buna-Werke Schkopau produced it in large quantities.

The material served u. a. as a leather substitute for shoe material and bags, for raincoats ("If you have igloo in the house, you can go out when it rains"), as flooring of inferior quality and also as packaging material. In the GDR it was particularly notorious as a shoe material (“hot in summer, cold in winter”). Igelite was nailed into windows as a replacement for glass during the last years of the war and after World War II. For this purpose, the 3 mm thick, flexible at room temperature table material was sold by glaziers or exchanged for natural produce. In the Leipzig area this sales took place z. B. by the then company Glas-Nebe. This substitute solution for glass was limited to regions near the igelite production (Leuna / Bitterfeld).

It was by delivering Orthotrikresylphosphat cause (OTKP) from its plasticizer nerve palsies. Therefore, its use in the GDR was severely restricted by an ordinance as early as 1950, which u. a. included a ban on use in the food and hygiene sector, as well as the obligation to label the relevant products with hazards.

However, it was not until July or August 1952 that the use of waste products from igelite production for Bino products , i.e. soup seasoning and stock cubes, was banned by the Ministry of Health of Saxony-Anhalt. The Bavarian Ministry of the Interior then ordered the confiscation of all stocks in Bavaria.
