Determining alternatives to DEHP for PVC medical devices
The high molecular weight of TOTM is an advantage over DOTP having to do with the phenomenon of stress cracking in connectors or other rigid components that interface with flexible PVC components such as tubing.
What is the best alternative to DEHP for medical-grade PVC
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.
Gas Chromatography-Mass Spectrometry (GC-MS) Information
Gas chromatography combined with a triple quadrupole mass spectrometry system is referred to as GC-MS/MS. The triple quadrupole MS provides a higher level of selectivity and is best suited to analyses where the highest sensitivity is required. This is often the case when quantitating pesticides in food or environmental contaminants.

[Apr 17, 2025] Dioctyl terephthalate (DOTP) is an organic compound with the molecular formula C24H38O4. It is a transparent oily liquid, insoluble in water, soluble in general organic solvents [1]. Dioctyl terephthalate is an excellent main plasticizer for polyvinyl chloride (PVC) plastics.
Antique and Vintage Jewelry Maker’s Marks: A Collector’s Guide
Aside from purity and maker’s marks, some jewelry will also bear symbols and letters, particularly hallmarks, inscribed on it. Many of these symbols and letters found on jewelry originate from assay offices. Jewelry from the United Kingdom contains a series of compulsory and optional jewelry marks set out by the countries’ assay offices.
- What are the properties of DOTP?
- The following are key properties of DOTP: Low Volatility: Ensures stability over time in PVC products. Excellent Durability: Resists degradation even in high-temperature environments. Eco-friendly: Free from phthalates, making it safer for humans and the environment.
- What is Dioctyl terephthalate (DOTP)?
- Dioctyl Terephthalate (DOTP) is a non-phthalate plasticizer used to improve the flexibility, durability, and overall performance of plastic products, especially polyvinyl chloride (PVC). What is DOTP?
- It is a safer alternative to traditional plasticizers, offering an eco-friendly solution for various industrial applications.
- Why is DOTP a good material?
- Its molecular structure provides excellent thermal stability, low volatility, and resistance to migration, making it ideal for long-lasting products. The following are key properties of DOTP: Low Volatility: Ensures stability over time in PVC products. Excellent Durability: Resists degradation even in high-temperature environments.
- What is the difference between DOP and DOTP?
- DOTP is often compared to DOP, a traditional plasticizer, due to its similar applications. However, DOTP has several key advantages: Performance DOTP: Superior heat resistance and durability. DOP: Moderate performance under high temperatures. Sustainability DOTP: A non-phthalate alternative, safer for the environment.
- What is DOTP used for?
- Automotive: DOTP is used in automotive interior trims, dashboards, and wiring insulation due to its high flexibility, thermal stability, and low toxicity. Construction: It is employed in flooring materials, roofing membranes, and wall coatings for its durability and ability to enhance flexibility.
- What are the advantages and disadvantages of DOTP?
- However, DOTP has several key advantages: Performance DOTP: Superior heat resistance and durability. DOP: Moderate performance under high temperatures. Sustainability DOTP: A non-phthalate alternative, safer for the environment. DOP: A phthalate-based plasticizer with a higher environmental impact.
