“…Furthermore, the peak of the C-H stretching vibration at 2849 and 2919 cm À1 does not show differences between an unirradiated and irradiated WPVC/ZnB (M) significantly that the hydrocarbon backbone is not degraded by EB-irradiation. 15 16 Also, WPVC filled with zinc borate using the melting mixing method displays several peaks at 2 thetas 17.7, 18.0, 20.5, 21.7, 22.5, 23.7, 24.1, 25.8, 27.5, 28.6, 30.2, 30.5, 30.7, 32.8, 35.9, 36.6, and 42.9°r espectively, those characteristic spectra of 2 ZnO•3B 2 O 3 •3.5 H 2 O. 17 It was observed that peaks around 2 thetas 18.7 and 25.0 were less intense in comparison with those that represent the pristine WPVC because the addition of zinc borate decreases the crystalline phase on WPVC.…”

In several works, scientific researchers targeted the development of polymeric materials with good mechanical and thermal properties and resist heat and fire propagation. In a new approach, this article goals to the usage of waste polyvinyl chloride (WPVC) based polymer composites derived from PVC pipes scrap filled with fixed percent of zinc borate particles (ZnB), which were prepared via two different techniques named melt mixing WPVC/ZnB (M) and casting WPVC/ZnB (C). The fabricated composites by the two methods were irradiated in an electron beam accelerator (EB) at 30 kGy. A comparative study of the thermal and mechanical properties based on stress-strain curves, tensile strength (TS), elongation at break (E %), and tear strength were evaluated. Furthermore, the rate of heat burning (%) for the two methods has been performed. Moreover, differential scanning calorimetry (DSC), Thermogravimetric analysis (TGA), Infrared spectroscopy analysis (FTIR), X-ray diffraction (XRD), and the activation energy (Ea) calculation of the prepared samples have been considered. The observed improvements in the mechanical, thermal, and flammability behavior of WPVC were succeeded by incorporating ZnB particles. The irradiated WPVC loaded with zinc borate presented a superior flame propagation fraction when matched with their corresponding unirradiated composites. Also, WPVC composite films prepared via the melt mixing method reveal more excellent properties than those equipped by the casting process for the most investigated factors.

“…The four films were examined in their initial state (i.e., 0%, 23°C) and at 50% strain for 23 versus 40°C as these conditions seemed to produce greater differences in gloss. The PUR film showed no crystallinity and the PVC film showed a weak peak at 2θ = 23.1 ° assigned to overlapping (210), (201), and (111) planes that was too small for analysis. This meant the XRD analysis was limited to the two PE/PP films.…”

Decorative polymer films are finding applications in processes that require forming at elevated temperatures and significant strain. In order to satisfy their function in these applications, the appearance of these films must remain unaltered or at least any changes must be predictable. This paper examines four different high gloss decorative films comprised of different materials in the layers of their construction. The films were uniaxially stretched up to failure (which was up to 75% strain) at isothermal conditions of 25, 40, or 758C and then examined. Gloss (at 208) was the most strongly altered parameter concerning the appearance of the films after thermomechanical deformation while color intensity was relatively unaffected. The change in gloss was higher for the two amorphous films compared to the two that exhibited crystallinity. The films were analyzed for their surface roughness using a white light interferometer, for their crystallinity by X-ray diffraction and for their morphology by atomic force microscopy

With the remarkable increase in whether heat in many countries, many scientific researchers aim to deal with this problem by developing polymeric materials that have good mechanical and thermal properties and are resistant to heat and fire. Polyvinyl chloride is used for decoration and construction materials. This article goals to the usage of waste polyvinyl chloride (WPVC) as based polymer composites containing zinc borate particles (ZnB) prepared via two different techniques equipped by melt mixing WPVC/ZnB (M) and casting WPVC/ZnB (C). The fabricated composites by the two methods were irradiated in an electron beam accelerator (EB) at 30 kGy. A comparative study of the mechanical, and thermal properties, as well as the rate of heat burning for the two methods, has been performed. Furthermore, activation energy calculation, FTIR, and XRD have been considered. The observed improvement in the mechanical, thermal, and flammability behavior of the samples was reached by the incorporation of ZnB particles and EB irradiation. Also, composites films prepared by melt mixing reveal superior properties than those equipped by casting for the most investigated factors.
