Application of ionic liquids as low-volatility plasticizers
The primary chemical structures of plasticizing agents include phthalate esters, adipates, trimellitates, and phosphates [1]. The structure of the widely-used DOP is shown in Fig. 1 as a representative of the general characteristics of many plasticizers. Although the IUPAC-approved name of this compound is diethylhexyl phthalate (DEHP), the
Effect of dioctyl phthalate (DOP) plasticizing agent on the
Effect of dioctyl phthalate (DOP) plasticizing agent on the dielectric properties of PVC insulation Abstract: The purpose of the paper is the investigation of the dielectric properties with respect to the plasticizer content in PVC materials.
Study on ionic liquid [bmim]PF6 and [hmim]PF6 as plasticizer
Thermal stabilities of two plasticizers were nearly same. The mass loss ratio at 250 °C decreased with plasticizer content increasing, it reduced to about 17% till 40 wt% plasticizers. Especially, when the plasticizer contents increased to 30 and 40 wt%, the mass loss ratio decreased distinctly.
Epoxidized castor oil‐based diglycidyl‐phthalate plasticizer
The plasticizing effects of ECODP as a replacement for commercial plasticizer dioctyl phthalate (DOP) were investigated. The thermal stability and mechanical properties of PVC films before and after aging were investigated using thermogravimetric analysis (TGA), TGA-FTIR analysis, dynamic mechanical analysis (DMA), and tensile tests.
Plasticizer
Diisoundecyl phthalate (DIUP), used for insulation of wires and cables, car undercoating, shoes, carpets, pool liners. Good high temperature and outdoor weathering performance Ditridecyl phthalate (DTDP) is the highest molecular weight phthalate plasticizer, providing greater performance at high temperature.
- What is dioctyl phthalate (DOP)?
- Dioctyl phthalate (DOP) is a widely-used plasticizer for NBR, and its structure is illustrated in Fig. 2. DOP has excellent compatibility with polymers, producing a strong plasticizing effect. It has low volatility, is not prone to precipitation, has low mobility, and boasts good resistance to water and organic matter extraction , , .
- Is dioctyl phthalate a plasticizer for NBR?
- Fig. 1. The polymerization process of the NBR. Dioctyl phthalate (DOP) is a widely-used plasticizer for NBR, and its structure is illustrated in Fig. 2. DOP has excellent compatibility with polymers, producing a strong plasticizing effect.
- Does dioctyl phthalate affect thermoplastic vulcanizate?
- In their study, Lin et al. investigated the influence of dioctyl phthalate (DOP) content on the mechanical properties, morphological evolution, Mullins effect, and reversibility of poly (lactic acid) (PLA)/acrylonitrile butadiene rubber (NBR) thermoplastic vulcanizate (TPV).
- How does DOP plasticization affect a polymer chain?
- The DOP plasticization of NBR reduced the intermolecular interaction forces and changed the molecular conformation, increasing the softness and plasticity of the polymer chains. 1. Introduction
- Does DOP affect mechanical properties of acrylonitrile-butadiene-styrene thermoplastic vulcanizate?
- In another study by Dong et al. , the influence of DOP content on the mechanical properties, Mullins effect, and microstructure of acrylonitrile-butadiene-styrene (ABS)/nitrile butadiene rubber (NBR) thermoplastic vulcanizate (TPV) was investigated. The addition of DOP significantly improved the mechanical properties of ABS/NBR TPVs.
- Does DOP increase steric hindrance?
- This signifies that the plasticizing effect of DOP does not continually increase with increasing DOP mass fraction, but increases up to a certain limit. Beyond this point, further addition of DOP molecular chains increases steric hindrance, thereby inhibiting intramolecular chain rotation and reducing plasticizing effect.
