Polyvinyl chloride (PVC) is a flexible or rigid material that is chemically nonreactive. Rigid PVC is easily machined, heat formed, welded, and even solvent cemented. PVC can also be machined using standard metal working tools and finished to close tolerances, and finishes without great difficulty.
Polyvinyl Chloride (PVC) is a versatile polymer widely used in various applications due to its cost-effectiveness and favorable physical, chemical, and weathering properties. It degrades at relatively low temperatures in the presence of light, releasing hydrogen chloride, but remains stable under anaerobic landfill conditions.
Polyvinyl chloride (PVC) ranks third among the most consumed plastics worldwide, following only polyethylene (PE) and polypropylene (PP). 1, 2 PVC plastics are used in myriad applications, including siding, flooring, plumbing, wiring, and medical packaging. Despite the breadth of properties exhibited by these commercial PVCs, pure PVC has a ...
Polyvinyl chloride (PVC), or vinyl for short, or using the IUPAC name ‘chloroethane’ or ‘poly (chloroethanediyl)’, with 57% of mass by chlorine, is an ‘infrastructure thermoplastic’ material. PVC is one of the most important plastic materials used worldwide in various phases of the construction industry, such as pipes, fittings and ...
Polyvinyl chloride (PVC) is a flexible or rigid material that is chemically nonreactive. Rigid PVC is easily machined, heat formed, welded, and even solvent cemented. PVC can also be machined using standard metal working tools and finished to close tolerances and finishes without great difficulty.
In this regard, low-cost polyvinyl chloride (PVC) has to gain significant consideration as a membrane material for the synthesis of microfiltration (MF) [21], [22], ultrafiltration (UF) [23], [24], and nanofiltration (NF) [25], [26] membranes due to its excellent properties such as good stiffness, high resistance to chlorine, bases, and acids ...
Polyvinyl chloride (PVC) microplastics present in sewage were trapped in sludge, thereby hindering anaerobic digestion performance of waste active sludge (WAS). Phages regulate virocell metabolism by encoding auxiliary metabolic genes (AMGs) related to energy acquisition and material degradation, supporting hosts survive in harsh environments ...
Polyvinyl chloride (PVC), a common plastic pollutant, is a prominent MP in soil [6]. As the third most common petroleum-based plastic, PVC manufacturing reached 5 million tons in 2018 [7]. When incinerated, particularly at around 200 °C, PVC emits various harmful chemicals, including polycyclic aromatic hydrocarbons and dioxins [8].
Due to the excellent physicochemical properties, polyvinyl chloride (PVC) plastics were widely used in product. The presence of macro and micro sized particles of PVC has been ubiquitously detected in the environment (Wang et al., 2020). PVC ranked as the most hazardous MPs with strong mutagenicity and carcinogenicity (Wei et al., 2019).
Polyvinyl chloride (PVC) is classified as a hazardous polymer due to the carcinogenicity of its monomers and the large amount of plasticizers (i.e., phthalates) used in its production [6]. PVC microplastics can also induce gastrointestinal disorders, gut microbe imbalances and metabolic disease in adult mice [7] and cause intestinal ...
