“…The flame retardant performance can also be investigated using SEM images of the surfaces of the residues of PVC samples after LOI tests . The morphologies of residues of PVC samples after the LOI tests were investigated using SEM as shown in Fig.…”

“…It is known that PVC itself is not easy to burn, due to the large amount of chlorine in the molecular structure of PVC. However, plasticized PVC is combustible and releases poisonous gas and smoke when burning, because of plasticizers such as dioctyl phthalate (DOP) with non‐flame retardancy and poor thermal stability . The easy combustibility of plasticizers limits the various applications of plasticized PVC products.…”

A novel plasticizer based on cardanol, hydrogenated cardanol glycidyl ether acetic ester containing phosphaphenanthrene group (HCGEP), was prepared and incorporated into poly(vinyl chloride) (PVC) for the first time. The molecular structure was characterized with Fourier transform infrared and 1H NMR spectroscopies. The thermal degradation behavior and flame retardant performance of PVC films with HCGEP as secondary or main plasticizer were investigated using thermogravimetric analysis, combustion tests, limiting oxygen index tests and morphological analysis of residues. Furthermore, the mechanical properties of PVC films were examined based on the results of tensile testing. The results were compared to those of the petroleum‐based plasticizer dioctyl phthalate. With the substitution of dioctyl phthalate with HCGEP, PVC films exhibited high thermal stability and better flame retardant performance. The tensile test results showed that the addition of HCGEP could endow PVC resin with well‐balanced properties of flexibility, strength and hardness. © 2017 Society of Chemical Industry

“…Plasticized PVC materials generally require higher thermal stability than that of pure PVC, because ester bonds or benzene groups with high thermal stability in the chemical structure of plasticizers such as dioctyl tetrahydrophthalate (DOTP) and epoxidized soybean oil, limiting the thermal degradation of those segments with lower thermal stability chain segments, then improving the thermal degradation stability of plasticized PVC materials. 46 In the study, thermal stability of PVC and selfplasticizing PVC materials were investigated, the TGA and DTG curves obtained for PVC and self-plasticizing PVC materials were presented in Fig. 8 and 9, respectively, and the thermal data including thermal degradation temperature (T d ) and peak temperature of thermal degradation (T p1 and T p2 ) were summarized in Table 3.…”

We developed an internal plasticizer of aminated tung oil methyl ester for the production of non-migration, phthalate-free flexible and internally plasticized poly(vinyl chloride) (PVC) materials. The chemical structure of the synthesized aminated tung oil methyl ester and the internally plasticized PVC materials were characterized. The obtained internally plasticized PVC materials presented a lower glass transition temperature (T g ) and were more flexible than pure PVC. The thermal stability of internally plasticized PVC materials was less thermally stable compared to those of pure PVC due to the active secondary amine groups of aminated tung oil methyl ester. However, the modified PVC materials presented no migration for self-plasticizing PVC films but 15.7% weight loss for 50 wt% of the PVC/Dioctyl phthalate (DOP) system. It is expected that the PVC materials can be widely used in areas with high migration resistance requirements.

“…6, all of the TGA curves exhibited two steps in the thermal degradation. The rst step in the temperature range 200-350 C corresponded to dehydrochlorination 21,22 and thermal decomposition of the plasticizer (DOP and THEIC-MR-phosphate). The second step occurred between 350 and 500 C and was attributed to the cyclization of the conjugated polyene sequences to form aromatic compounds.…”
