An introduction of PVC

Yangzhou Chengsen Plastics Co.,Ltd | Updated: Mar 09, 2018

Polyvinylchloride (PVC) [-(-CH2 -CHCl-)n-] is one of the three most important polymers currently used worldwide. This is because PVC is one of the cheapest polymers to make and has a large range of properties so can be used to make hundreds of products. PVC is formed by the polymerisation of vinyl chloride (chloroethane) monomer units:

PVC consists of polar molecules which are attracted to each other by dipole-dipole interactions due to electrostatic attractions of a chlorine atom in one molecule to a hydrogen atom in another atom:

These considerable intermolecular attractions between polymer chains make PVC a fairly strong material.

Uncompounded PVC is colourless and rigid and possesses poor stability towards heat and light. However, the use of additives/stabilisers enables us to change the properties of the PVC to how we desire.
