Find out more about the history of plastics and how they came to be. Advanced Recycling Technologies ARTs are essential to ensuring that plastics stay out of the environment, while also creating new products and economic growth opportunities that benefit society. From interior components to structural elements, here's how aircraft plastics fortify the aerospace and aviation industries.
Plastic packaging protects products in transit and with a lower environmental impact than alternatives. With more consumers using e-commerce than ever before, industry is leading the way in developing new recycling initiatives that address waste challenges.

High-density polyethylene HDPE Polyethylene is the world's most common plastic, and it most often appears in three forms: high-density, low-density and linear low-density we'll discuss those more below. Linear low-density polyethylene LLDPE A tweak of the chemistry when processing LDPE yields linear LDPE, which is used in plastic bags—both the kinds you can get at the grocery checkout and the kinds that extend the shelf life of foods, such as lettuce and cauliflower, by weeks.
Polypropylene PP PP is more heat resistant than some other plastics, making it ideal for use in food packaging and food storage that's made to hold hot items or be heated itself.
Polypropylene sheeting also possesses a very favorable strength to weight ratio. Need Help? Call Acrylic or Polymethyl Methacrylate PMMA Well-known for its use in optical devices and products, acrylic is a transparent thermoplastic used as a lightweight, shatter-resistant alternative to glass. Polycarbonate PC Tough, stable, and transparent, polycarbonate is an excellent engineering plastic that is as clear as glass and two hundred and fifty times stronger.
Polyethylene PE The most common plastic on earth, polyethylene can be manufactured in varying densities. Here are the four common polyethylene densities: Low-Density Polyethylene LDPE This density of polyethylene is ductile and used to make products like shopping bags, plastic bags, clear food containers, disposable packaging, etc. Acrylonitrile-Butadiene-Styrene ABS Created by polymerizing styrene and acrylonitrile in the presence of polybutadiene, ABS is robust, flexible, glossy, highly processable, and impact resistant.

Examples: Plumbing pipes, credit cards, human and pet toys, rain gutters, teething rings, IV fluid bags and medical tubing and oxygen masks. A softer, clearer, and more flexible version of HDPE.
This is one of the most durable types of plastic. Polystyrene, more commonly known as styrofoam. Better known as Styrofoam, this rigid plastic is low-cost and insulates very well, which has made it a staple in the food, packaging and construction industries.
Like PVC, polystyrene is considered to be a dangerous plastic. It can easily leach harmful toxins such as styrene a neurotoxin , which can easily then be absorbed by food and thus ingested by humans. Another may be transparent like glass yet tough. Or stretch and bounce back in shape. Another may trap air inside itself. Or stop a bullet. Plastics are a result of a mix of chemistry and engineering.
As innovation marches on, scientists and engineers can create new plastics to do more and more things. So even though the number of plastics is unclear, plastics makers tend to group plastics into two general classes: thermoplastics and thermosets. Can be re-melted and essentially returned to their original state—sort of like the way an ice cube can be melted and then cooled again.
