“…Generally speaking, polyvinyl chloride can be processed into all sorts of plastic materials through mixing, plasticization, and molding (Wang et al 2015a). By using different types and proportions of processing aids, various hard, semi-hard, soft, transparent, and non-transparent polyvinyl chloride materials can be produced (Wang et al 2015a). Typically, polyvinyl chloride products can include copolymers or alloys, synthetic fibers, engineering plastics, coatings, elastomers, foams, sealants, and different types of special functional materials (Wang et al 2015a).…”
