Plasticizer < Our Business | OCI
Plasticizers are categorized as phthalate-based, trimellitate-based, phosphoric acid-based and epoxy-based depending on the base material. It is produced by the ester reaction between alcohol such as Octanol (2-EH), INA, etc., and acids such as PA, TPA, TMA, etc. Depending on the base material, different grades of plasticizers are produced.

production [3,19]. In addition to DINP and DEHP, other common phthalate plasticizers have been used in many plastic products. Because of their abundance in children’s products, quantitative assessment of exposure to phthalate plasticizers should be prioritized.

US6310235B1 - Method for producing ester plasticizers
The invention relates to an improved method for producing ester plasticizers by reacting di- or polycarboxylic acids or their anhydrides with alcohols in the presence of metal catalysts. Description This application is a 371 of PCT/EP98/02899 filed May 16, 1998.
US Patent for Method for producing plasticizers Patent
BACKGROUND OF THE INVENTION. 1. Field of the Invention. This invention relates to a method for producing a plasticizer from the ester obtained by reacting phthalic anhydride with an alcohol having 4-18 carbon atoms in the presence of as a catalyst, a tetraalkyl titanate or a polymer thereof.
- Are there phthalates and non-phthalate plasticizers in the coastal environment of Korea?
- Conclusions This is the first nation-wide survey of phthalates and non-phthalate plasticizers in the coastal environment of Korea. Phthalates and alternative plasticizers were detected in all sediment samples from the coastal zone of Korea. DEHP and DEHT were the dominant phthalates and NPPs, respectively.
- Where is plasticizer made?
- Up to 6.5 tons of it will be produced every year at a petrochemical industrial complex in the southeastern port city of Ulsan, South Korea. Plasticizer is a chemical substance capable of making plastics softer, and phthalate is one of the most common materials to achieve it.
- Are phthalates and non-phthalate plasticizers found in coastal sediment?
- Korea is the world's largest consumer of plastic, with increasing production and consumption ( European Plastics and Rubber Machinery, 2016 ). The present study assesses the occurrence, spatial distribution, and potential contamination sources of phthalates and non-phthalate plasticizers in coastal sediment from Korean coastal waters.
- What are plasticizers used for?
- They are raw materials to produce wire compounds, wallpaper, flooring, PVC film, automotive sealant (sealer), synthetic leather, etc. Plasticizers are categorized as phthalate-based, trimellitate-based, phosphoric acid-based and epoxy-based depending on the base material.
- What are the different types of plasticizers?
- Plasticizers are categorized as phthalate-based, trimellitate-based, phosphoric acid-based and epoxy-based depending on the base material. It is produced by the ester reaction between alcohol such as Octanol (2-EH), INA, etc., and acids such as PA, TPA, TMA, etc. Depending on the base material, different grades of plasticizers are produced.
- What is OCI plasticizer?
- OCI produces plasticizers that improve the flexibility and low-temperature resistance of PVC products. Plasticizers improve the flexibility, low-temperature resistance, and processability of PVC products. They are raw materials to produce wire compounds, wallpaper, flooring, PVC film, automotive sealant (sealer), synthetic leather, etc.
