Hey as per my idea PVC is Polyvinyl chloride and here I am giving you its basic information

PVC
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.

Structure


The polymers are linear and are strong. The monomers are mainly arranged
head-to-tail, meaning that there are chlorides on alternating carbon centres.

PVC has mainly an atactic stereochemistry, which means that the relative
stereochemistry of the chloride centres are random.

Some degree of syndiotacticity of the chain gives a few percent crystallinity
that is influential on the properties of the material.

About 57% of the mass of PVC is chlorine.

The presence of chloride groups gives the polymer very different properties
from the structurally related material polyethylene


Properties

PVC has high hardness and mechanical properties.

The mechanical properties enhance with the molecular weight increasing but
decrease with the temperature increasing.

The mechanical properties of rigid PVC (uPVC) are very good; the elastic
modulus can reach 1500-3,000 MPa. The soft PVC (flexible PVC) elastic is
1.5–15 MPa.
