Beschreibung
Zusammenfassung:	The disclosed technology relates to a plastic compound suitable for preparing articles, such as pipe fittings and valves, with good physical properties, such as impact strength, and resistance to environmental stress cracking (ESC). In particular, the technology relates to a vinyl chloride resin, which includes chlorinated polyvinyl chloride ("CPVC") homopolymer. Furthermore, the invention relates to vinyl chloride homopolymer compounds containing the vinyl chloride homopolymer resin, and articles made from such compounds, which compounds meet 23447 cell classifications under ASTM D1784.
