Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

The chemical properties of polymer discussed here include chemical resistance, chemical permeation, and weather resistance. The major component of the polymer is hydrocarbon which results in hydrophobic property in general. They are usually resistant to polar solvent but will be attacked by nonpolar solvent.

What are the advantages and disadvantages of using plastics? It depends on what type of plastics we're dealing with. Let's take plastic bags for instance: The advantages of plastics: It is durable, low cost, water resistant, lesser energy and heavy chemicals requirements in manufacture and are light weight.

Types of Plastic Many food grade plastic containers fall into the high density polyethylene — or HDPE — category. It has excellent chemical resistant properties making it suitable for a wide range of foods and other products. For example, most juice or milk containers and five gallon food buckets are made from HDPE.

Raw materials used to make plastic include carbon-rich oil and carbon compounds, called monomers, that are mixed with oxygen, sulphur or nitrogen. Organic compounds, such as ethylene, propylene, styrene, phenol, formaldehyde, ethylene glycol, vinyl chloride and acetonitrile, can also be found in plastics.

Plastics are everywhere. ... Plastics are made from oil. Oil is a carbon-rich raw material, and plastics are large carbon-containing compounds. They're large molecules called polymers, which are composed of repeating units of shorter carbon-containing compounds called monomers.

Chemical properties: Unplasticized PVC resists very well (up to 60°C) acids and bases as well as oils, alcohols and aliphatic hydrocarbons. By contrast, it is sensitive to aromatic and chlorinated hydrocarbons, esters and cetones that produce a swelling. Flexible PVC is sensitive to atmospheric agents and sunlight.

Plastic - Boon or Bane. ... The fact that plastic is lightweight, does not rust or rot, helps lower transportation costs and conserves natural resources is the reason for which plastic has gained this much popularity. Plastics are everywhere and have innumerable uses! Plastics are durable, lightweight, and reusable.

Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.
