Does plastic have a fixed chemical formula?

Plastic is not mineral. It is a solid and it has a definite chemical composition.

What type of chemical is plastic?

Polymers often are made of carbon and hydrogen and sometimes oxygen, nitrogen, sulfur, chlorine, fluorine, phosphorous, or silicon. The term “plastics” encompasses all these various polymers. Although there are many polymers, plastics in general are lightweight with significant degrees of strength.

Do all plastics have the same chemical composition?

For the purposes of this article, plastics are primarily defined not on the basis of their chemical composition but on the basis of their engineering behaviour. More specifically, they are defined as either thermoplastic resins or thermosetting resins.

What is PVC plastic made of?

The essential raw materials for PVC are derived from salt and oil. The electrolysis of salt water produces chlorine, which is combined with ethylene (obtained from oil) to form vinyl chloride monomer (VCM).

Is Fibre a plastic?

1 Types of Fibers. Optical fibers are made of plastic, glass, or silica. Plastic fibers are the least efficient but tend to be larger, more economical, and more rugged. Glass or silica fibers are much smaller, and their lower attenuation loss makes them more suited to high-capacity channels.

What plastic is made of?

Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane. Ethane and propane are then treated with heat in a process called “cracking” which turns them into ethylene and propylene. These materials are combined together to create different polymers.

What are chemical properties of plastic?

Plastics can be classified by the chemical process used in their synthesis, such as condensation, polyaddition, and cross-linking. They can also be classified by their physical properties, including hardness, density, tensile strength, thermal resistance, and glass transition temperature.
