2-Propylheptanol (2-PH) - Evonik Industries
It can be used both in the production of plasticizers and as a raw material for the production of surface-active substances. DPHP, a plasticizer produced from 2-PH, is mainly used in the production of flexible PVC products for the construction industry. Surfactants based on 2-PH are used in a wide range of cleaning agents.
What is DEHP? Where is it used? Why is it used? | U.S. Plastic
Plasticizers are essential to make PVC flexible. PVC is naturally rigid, but plasticizers are added to make the tubing flexible and expandable while retaining its shape. DEHP is widely used because it is low cost, processes well, and has provided good end-use performance.
Simultaneous recovery of high-purity copper and polyvinyl
1. Introduction Polyvinyl chloride (PVC) has become an indispensable resin because of its high chemical and physical stability. Compared with other resins, PVC consists of a high percentage of Cl (57 wt%), which allows its combination with a wide variety of additives such as plasticizers, stabilizers, flame retardants, and fillers.

- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- How are plasticizers extracted from PVC-tubing?
- Plasticizers were extracted from PVC-tubing by dissolving PVC in THF then precipitating it in methanol with a yield of over 90% for each plasticizer. This assay could feasibly be used to quantify plasticizers in PVC medical devices. 1. Introduction
- Why is plasticizer important?
- Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC. Therefore, plasticizers are the most important commercial application of PVC. However, plasticizers can leach out of flexible PVC, changing the performance of PVC with age and contaminating the environment.
- How do plasticizers affect the performance of PVC products?
- Plasticizers influence the flexibility, workability, and durability of PVC products. Choosing the right type of plasticizer can enhance the performance characteristics of PVC while also addressing environmental and health concerns.
- Which Green plasticizers are used for internal plasticization of PVC?
- In this study, the tributhyl citrate (TBC), propargyl ether tributhyl citrate (PrTBC), oleic acid and poly (dimethylsiloxane) diglycidyl ether terminated (PDMS, Mn ≃ 800) have been used as four different green plasticizers to internal plasticization of PVC.
