Understanding Plastic Basics

Chemical Composition

Plastics are made up of long chains of molecules known as polymers, which give them their unique, flexible properties. These polymers, often containing additives, consist of repeated units called monomers, linked together in a process called polymerization. The chemical structure of these polymers determines the plastic's characteristics and potential uses.

Polymers can be natural, like cellulose in plants, or synthetic, which, with additives, are the basis for most plastics we use today. Synthetic polymers are crafted from petroleum and natural gas, making them highly versatile but also a concern for environmental sustainability.

Thermoplastics vs. Thermosets

Thermoplastics and thermosetting plastics, each with distinct properties and applications, represent two primary categories of plastics that often incorporate additives.

Thermoplastics become soft when heated and harden upon cooling without undergoing any chemical change. This property allows them to be remolded and recycled multiple times, making them highly versatile for various applications. Common examples include polyethylene (PE), used in shopping bags, and polyvinyl chloride (PVC), used in plumbing pipes.

Thermosetting plastics, on the other hand, undergo a chemical change when heated, creating a rigid three-dimensional network that cannot be remolded or recycled easily. They are valued for their durability and heat resistance. Examples include epoxy resins used in adhesives and fiberglass.

Lifecycle of Plastics

The lifecycle of a plastic product begins with the extraction of raw materials, primarily crude oil and natural gas. These materials are then refined into basic chemical compounds that form the building blocks of plastics.

Manufacturing processes transform these compounds into polymers through polymerization. The resulting polymers are then shaped into final products through various methods such as injection molding, extrusion, or blow molding.

After their useful life ends, plastic products face either recycling, where they are reprocessed into new items; incineration for energy recovery; or landfilling. Recycling rates vary widely among different types of plastics due to differences in chemical composition and economic feasibility.
