The Wonderful World of Plastics
Check the shelves of your local mega-store and you’ll be hard-pressed to find a product that doesn’t have a plastic component. Since the introduction of Bakelite in 1907, plastics have become essential materials for manufacturers of all product types. Synthetic plastics are found in home exteriors, car interiors, clothing, product packaging, toys, tools, medical components and electronics. Lightweight, durable and formable into an infinite variety of shapes, plastics will continue to inspire new product development for years to come.
What Makes Plastics So Versatile?
Most modern synthetic plastics are carbon-based polymers, chemical compounds with high molecular weights and repeatable sub-units that can form long chains or complex structures. The compounds are created when carbon atoms are combined with other elements like hydrogen, nitrogen, oxygen, sulfur or chlorine. There are thousands of these combinations, each with unique properties.
Today, the vast majority of plastic products are made from thermoplastic compounds, polymers comprised of long chains of repeatable molecular units and distinguished by their melting capability. Manufacturing processes like injection molding, extrusion, and calendaring form these thermoplastics into the array of contrasting products we find on store shelves today.
Widely Used Thermoplastics & the Products They Form
- Polyethylenes (HDPE) (MDPE) (LDPE) (PET)—This group of compounds makes up the most widely used type of plastics. Polyethylenes are found in shopping bags, freezer containers, detergent bottles, agricultural pipes, squeeze bottles, trash bags and bins, water bottles, food containers, medicine bottles, beauty products and rope.
- olyvinyl Chloride (PVC)—A thermoplastic that is highly resistant to weather and other environmental factors, PVC can be rigid or flexible and is used for plumbing pipe, hoses, shoe soles, roof sheeting, home siding, medical bags and tubing.
- Polypropylene (PP)—Strong, flexible and resistant to moisture and corrosion, this thermoplastic is made into products as diverse as food bags and containers, straws, packing tape, medicine bottles, thermal clothing, garden furniture and electrical insulation.
