"Plastic" is a term applied to any material which can be molded or bent into shape. So for instance soft toffee, modeling clay or red hot iron is plastic because it can be reshaped. In general, though when we speak of plastic, we mean polymers or synthetic materials made from petrochemicals.

There are at least 10 different types of plastics used in the home, the type used depending on the application. Many of these plastics can be recycled and are marked with a symbol and numeric code indicating the plastic type.

Types of Plastic Used Around the Home

There are lots of different types of plastics used in and about the home. The most common ones are:

Polyethylene (Polythene)

Poly Vinyl Chloride (PVC) also known as vinyl

Polypropylene

Polystyrene

Polytetrafluoroethylene (Teflon)

Nylon

Polyesters, polyethylene terephthalate (PET) being the most common

Acrylic

Polycarbonate

Polyurethane

Note: These numbers are not the plastic ID codes. See the information about each plastic below for codes.

Well virtually everything! From the sixties onwards, plastic began to replace or supplement many items which were traditionally made from materials such as metal, wood, glass, stone, ceramic and natural textiles. Some examples:

Textiles: Cotton, wool, silk, linen and hemp were the original textiles used from ancient times. We now have acrylic, polyester and nylon

Footwear: Shoes originally had leather uppers and soles. PVC is now used for sneakers, and soles are made from PVC or polyurethane foam

Windows and doors: Originally made from timber, they are now also made from PVC

Food storage, eating and drinking utensils and bottles: They were originally ceramic, glass or metal but are now also made from polyester, polypropylene and polyethylene (Polythene)
