Plasticized lignin-PVC blends for flooring
… studies the feasibility of replacing part of the PVC in the formulation of flooring materials by lignin, an abundant and renewable natural polymer. The utilization of lignin, is aimed to develop more cost-effective flooring materials with appreciable mechanical properties, to decrease their …

PVC stabilisers based on metal carboxylates
… are formed rapidly in Polyvinyl chloride (PVC) as a consequence of mechanical shearing of the polymer chains during the processing operation. The concentration of these species in the polymer before processing is negligible compared with that produced mechano-chemically during processing. …

Fatigue and fracture behaviour of PVC at elevated temperatures
… of failures in underground water-carrying uPVC piping in a luxury resort in Dubai gave rise to a research opportunity to determine the effect of temperature on fatigue life performance of uPVC piping. Two different modes of testing were used to determine this temperature effect, namely SN …

Fatigue and fracture behaviour of PVC at elevated temperatures
The research studies revealed that there was a distinct difference in fatigue performance as a result of a temperature increase from 20°C to 45°C, as characterised by both SN and Paris fatigue tests. There was also, but to a lesser degree, an ageing effect. The temperature performance factor for …

Behavior of concrete-filled pvc tube columns under axial load
… widely used. However, the application of FRP and PVC came into the picture as the alternative to the steel application in the system. In this study, the concrete-filled PVC tube (CF-PVCT) columns subjected to axial load were considered in both experimental and numerical analysis. The PVC tube is a …

Effects of plasticizers on extrusion of PVC: an experimental & numerical study
… the processing behavior of Polyvinyl Chloride (PVC). However, when the plasticizer type is changed, various complaints are made by the processors that the material no longer processes the same. This research was concerned with the effect of three different plasticizers on the plasticating …

Functionalization of PVC using a mussel-inspired coating strategy to target the polymicrobial nature of ventilator-associated pneumonia
… in vitro tasks. In parallel, polyvinyl chloride (PVC) was functionalized using an adhesive dopamine-based strategy, applying safe-by-design criteria, to prevent single, dual, and triple adhesion and biofilm formation of VAPrelevant pathogens: P. aeruginosa, Staphylococcus aureus, and C. albicans. …
