PVC är ett vitt pulver som saknar lukt och smak. Smälts pulvret bildar det en styv fileärglös polymer med densiteten cirka 1400 kg/m³ och med en mjukningstemperatur vid cirka 82°C.
PVC manufacturing requires a system often called polymerization, whereby monomers of vinyl chloride are chemically bonded to variety a polymer chain. The 2 major varieties of polymerization used are suspension polymerization and emulsion polymerization.
