DOTP is a general-purpose plasticizer, with the added advantage that it is considered “phthalate free” within the plastic industry, meaning that it does not contain ortho
- How is high-purity DOTP obtained?
- High-purity DOTP is obtained through this process. Many parameters need to be monitored in order to guarantee a high reaction yield and high DOTP quality. Traditionally, the amount of reactants and products are measured in the laboratory after taking a sample from the production process.
- What is the difference between DOTP & TOTM plasticizers?
- Purity. If processed in truly dedicated equipment, DOTP can be produced nearly free of DEHP contamination. DOTP plasticizer producers specify a DEHP content of less than 50 parts per million, but almost all shipments contain significantly less than that. By contrast, TOTM can contain as much as 2,000 ppm of DEHP and is never free of it.
- What is DOTP & how does it work?
- DOTP is mainly manufactured by direct esterification. Many process parameters need to be monitored simultaneously to guarantee high product quality and high reaction throughput—something that is not possible with traditional laboratory analysis.
- Does DOTP craze better than TOTM?
- “DOTP may cause more crazing than TOTM but resists crazing better than other alternative plasticizers and even better than DEHP. TOTM is also outperformed in this regard by polymeric plasticizers. Over the years, moreover, device manufacturers have avoided serious crazing issues with DEHP through appropriate design and other measures.
- Is DOTP a good replacement for DEHP?
- In all respects, except for the issue of crazing, DOTP appears to be the preferable candidate for replacing DEHP. In fact, although DOTP is a relative newcomer to the global marketplace, it already outsells TOTM by a ratio of 12 to 2.
- Is DOTP a liquid or liquid?
- DOTP is normally supplied as a Liquid in 200kg Drum. DOTP is not formulated to contain any hazardous or regulated materials such as lead, cadmium, mercury, and chromium compounds. And Hanwha Chemical corporation guarantee that DOTP do not include any hazardous or regulated materials during the manufacturing process.
