History
In 1927, the first vinyl plastic to be commercially manufactured was PVC.
Features
Vinyl can be as flexible as cloth or as rigid and stiff as wood. It can be made in any color, and it can even be transparent.
Function
Vinyl is used to make vinyl phonographic records, leather-like upholstery, toys, furniture, flooring, luggage, raincoats, milk cartons, and many other products.
Significance
Vinyl is rugged and it does not easily tear or break. It can withstand exposure to some acids, oils, alcohol, and water.
Ingredients
Vinyl is made from petroleum, natural gas and salt. Vinyl burns slowly, and it will begin to loose its shape when it reaches 150 degrees Fahrenheit.
Types
There are different types of vinyl. All vinyl contains a chemical called vinyl, with the formual: CH2 CH.
Warning
In the 1970's, research indicated that breathing vinyl chloride--used in making PVC pipe--caused serious health hazards. Changes were made to improve the air quality of manufacturers making the plastics.
