Abstract In this work, the torque rheology, mechanical properties, migration resistance, thermal deformation, and Vicat softening point temperature of PVC plasticized by four environmentally friendly plasticizers are investigated. The experimental results reveal that the plasticizer’s heavy metal content meets production requirements while falling below the limiting standard. Plasticizer melting points differ, as do the enthalpy and torque of the entire melting process, resulting in different energy consumption when melting plasticizers. Also, the mechanical properties of PVC are not different

This paper explores the influence of selected commercial plasticizers structure, which are based on esters of citric acid, on mechanical and thermal properties of Poly(3-hydroxybutyrate)/Poly(lactic acid)/Plasticizer biodegradable blends. These plasticizers were first tested with respect to their miscibility with Poly(3-hydroxybutyrate)/Poly(lactic acid) (PHB/PLA) blends using a kneading machine. PHB/PLA/plasticizer blends in the weight ratio (wt %) of 60/25/15 were then prepared by single screw and corotating meshing twin screw extruders in the form of filament for further three-dimensional (

The research included corn starch (CS) films using sorbitol (S), glycerol (G), and their combination (SG) as plasticizers at 30, 45, and 60 wt %, with a traditional solution casting technique. The introduction of plasticizer to CS film-forming solutions led to solving the fragility and brittleness of CS films. The increased concentration of plasticizers contributed to an improvement in film thickness, weight, and humidity. Conversely, plasticized films reduced their density and water absorption, with increasing plasticizer concentrations. The increase in the amount of the plasticizer from 30 t

In this paper, three different plasticizer molecular sizes namely; glycerol (C3), tributyrin (C15) and trilaurin (C32) was used as non-carcinogenic plasticizers in poly(vinyl chloride) (PVC). The experimental results indicated that all the plasticizers play an important role of PVC toughening. Among of these plasticizers, tributyrin was the most effective for PVC plasticization due to its suitable molecular size. With the presence of tributyrin, PVC was found to tougher and softer which reflected as the increased tensile elongation at break, impact strength and the decreased tensile strength.

Plasticizers differed primarily in chemical structure (polarity) and molecular weight (monomeric vs polymeric). Plasticizer addition led to lower viscosity, maximum torque, modulus, tensile strength, and enhanced low temperature properties. Exposure to jet fuel caused plasticizer extraction resulting in compound softening due to absorption of the aromatic components in the fuel. The glass transition temperature shifted to

Plasticizers are the binding substances used to increase the elasticity of materials. In this research work, bioplastic is extracted from banana peels using various plasticizers such as, glycerol, urea, distilled water and glucose. The prepared bioplastics were characterized by using Fourier-transform infrared spectroscopy (FTIR) spectroscopic analysis which showed that the peak at 3355 cm-1 indicate the H-bonding formation between N-H urea and starch. The physicochemical properties such as water absorption test, soil decomposition and load test of synthesized bioplastics were analyzed at ambi

Low-molecular-weight plasticizers are commonly used in the production of plasticized PVC. However, they readily migrate to the surface of the product, which results in the deterioration of physical properties and contamination of environment. This drawback is eliminated by polymerizing vinyl chloride in water suspension in the presence of a polyester plasticizer and structure stabilizer such as triallyl isocyanurate or the ethylene/vinyl acetate copolymer. The data obtained from water and heptane extractions demonstrate a low extractability of the plasticizer used. Attention is focused on the

The use of vegetable oil-dervied plasticizers to enhance the flexibility of polylactic acid (PLA) has received much attention due to their renewability, inexpensiveness and biodegradation. However, the double bonds in vegetable oil-based plasticizers limit their compatibility with PLA, resulting in PLA-derived products with reduced flexibility. Herein, we examined soybean oil-derived hydrogenated dimer acid-based polyethylene glycol methyl ether esters (HDA-2n, 2n = 2, 4, 6 or 8, referring to the ethoxy units) developed via the direct esterification of saturated hydrogenated dimer acid and pol

It is found that the crosslink density and modulus of MSO- plasticized rubber are significantly improved compared with that of SO-plasticized TR. MSO modified with 6 wt % sulfur (MSO-6%) exhibits the best plasticization effect on TR, thus, the plasticization effect of MSO-6% on T

This trend is consistent across various PVC samples, despite minor variations. The role of plasticizers in determining the physical and mechanical properties of PVC is further explored, emphasizing their function in reducing PVC’s crystallinity, thereby produci
