The us-based plastics industry association (plastics), formerly known as the society of the plastics industry (spi), established a classification system in 1988 to allow consumers and recyclers to identify different types of plastic via a code or number that is usually moulded at the bottom of each plastic product. The most common type of thermoplastics, polyolefins are also the some of the most widely used type of plastic in fact, polyethylene and polypropylene are the most ubiquitous plastics in the world, with variations of each used in a staggering array of products, from soda bottles caps to lab instruments.

The chemical industry produces different types of plastic there are seven primary groups in 1988 the society of the plastics industry (spi) created a coding system that assists recyclers with the recycling of plastics. Plastics that are capable of being broken down into carbon dioxide, water and minerals by natural processes (microbes, sunlight and hydrolysis) are considered to be biodegradable. Plastics can be divided into two major categories: 1 thermoset or thermosetting plastics once cooled and hardened, these plastics retain their shapes and cannot return to their original form they are hard and durable thermosets can be used for auto parts, aircraft parts and tires examples.

Plastics plastics are used in model-making and packaging types of plastic and their uses material properties uses acrylic: stiff and brittle brittle: if something is brittle it is easily broken. There are more than a thousand different types of plastic plastics can be broken down into broad categories: thermoplastics, thermosets, engineering plastics, plastic fibers, coatings, elastomers, rubbers, adhesives and more.
Most plastic products are marked with a number that corresponds to the type of plastic that it is made of the number, known as a recycling code, can be found within the triangular recycling symbol (see above) that recyclable plastics are marked with. Below are five of the most common plastics used for different applications along with their properties, uses and trade names polyethylene terephthalate, pet or pete, is a durable thermoplastic that shows tough resistance to chemicals, high energy radiation, moisture, weather, wear and abrasion.
