A Strategy for 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...

Recent Attempts in the Design of Efficient PVC Plasticizers with

A PVC blend with synthesised hyperbranched plasticizers with the highest ratio (15:1) of caprolactone: polyester (named HEPCL) exhibited the lowest T performed better than DOP in terms of mechanical properties, and at the same time exhibited the highest migration resistance. 2.1.3. Other Branched and Hyperbranched Plasticizers

Further Step in the Transition from Conventional Plasticizers to

In the last two decades, the use of phthalates has been restricted worldwide due to their well-known toxicity. Nonetheless, phthalates are still widely used for their versatility, high plasticization effect, low cost, and lack of valuable alternatives. This study presents the fully bio-based and versatile glycerol trilevulinate plasticizer (GT) that was obtained by the valorization of glycerol ...

Synthesis of novel plasticizer ester end-capped oligomeric lactic acid

In this work, a novel high efficiency plasticizer, an ester-capped oligomeric lactic acid mixture (EOL), was successfully synthesized by a two-step esterification reaction, with L -lactic acid as the main raw material. The structure of EOL was characterized by using FT-IR, 1 H NMR and time of flight mass spectrometry (TOF-MS).

Until now, phthalates, such as di-2-ethylhexyl phthalate (DEHP), also known as dioctyl phthalate (DOP), are still the most used commercial PVC plasticizer, occupying over 70% of the market . Despite the considerable advantages, petroleum-based plasticizers are prone to migrate from PVC products due to the lack of chemical bond between plasticizers and PVC segment [ 8 , 9 , 10 ].

Bio-based Hyperbranched Ester Plasticizers from Woody Oil ...

Developing bio-based hyperbranched ester plasticizers using woody oil by a simple strategy to replace toxic phthalate plasticizers has significant social, environmental, and economic significance. Herein, a series of tung oil-based hyperbranched esters (TPPs) were synthesis through a one-pot method, the degree of branching and relative molecular weight of the TPPs were controlled by adjusting ...
