Many plastics are derived from crude oil.
It's not that what they make plastics with.

1% or less of all oil consumption goes toward making plastics, so it is a sustainable source. However, we also consume oil as fuel, and THAT is where oil becomes an unsustainable source. If we can move away from oil as a fuel, then oil becomes sustainable.
Most plastics are made from fossil fuel oil, so they are not eco friendly. Plastics made from vegetable oil are eco-friendly because they biodegrade (decompose) into organic matter.
All the plastics are made from oil. Most of the fuels are made from oil.

The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
Crude oil undergoes a process called fractional distillation to separate it into different components such as gasoline, diesel, jet fuel, and lubricants. From these components, useful substances like petrochemicals, plastics, solvents, and waxes can be extracted. These substances are used in various industries including manufacturing, chemicals, pharmaceuticals, and cosmetics.
Though petrochemicals are a critically important source of materials for plastics (and for many, many other products and industrial feedstocks), most oil and hydrocarbon resources (coal, gas, etc.) are used as fuels. It's that simple.
PVC, like other plastics, is primarily a chain of hydrocarbons derived from oil.
All plastics are a by product of crude oil.
