PVC is most often produced with the help of an organic peroxide initiator and since Nouryon is the world's largest producer of organic peroxides, the company is an integral player in the PVC industry.
Building on its extensive know-how the PVC technical team of AkzoNobel has turned an old dream of the industry into reality: continuously and controlled charging of the initiator (Continuous Initiator Dosing or CiD) to fully control and optimize the vinylchloride polymerization reaction. Thus economic, operational, quality, safety and environmental advantages are brought to the industry.
PVC is the third most widely produced plastic in the world, with annual production of approximately 34 million tons.
Several inventions had to be brought together to make CiD a success:
Also, AkzoNobel has built several CiD demonstration units to facilitate the introduction at customers’ sites. These demo units can show the viability of CiD introduction by running multiple batches on one or multiple reactors under supervision of AkzoNobel experts in close cooperation with customers’ operational teams.
CiD has already been introduced at six customers worldwide with a number of trials ongoing. This experience has shown that the use of our CiD technology can bring the following benefits:
