UV-ljus och temperatur anses vara de faktorer som svarar fileör den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.
PVC manufacturing involves a process often called polymerization, whereby monomers of vinyl chloride are chemically bonded to variety a polymer chain. The 2 main varieties of polymerization applied are suspension polymerization and emulsion polymerization.

Emulsion Polymerization: In this technique, vinyl chloride monomers are emulsified in drinking water with the help of surfactants. The polymerization response is then initiated by free of charge radicals.
塩ビは安価かつ大量に生産されているエチレンと塩素を原料としており、石油を原料とする他のプラスチック製品と比べて省資源で製造できます。
Subsequent, the alerts get there at a cluster of cells called the atrioventricular (AV) node, wherever they slow down. This slight delay will allow the ventricles to fill with blood. If the electrical signals get to the ventricles, the chambers agreement and pump blood for the lungs or to the rest of the overall body.
