Plastic and resins
polyethylene or polythene (PE; IUPAC name polyethene) is the most common plastic in use today. It is a linear, man-made, addition, homo-polymer, primarily used for packaging (plastic bags, plastic films, geomembranes, containers including bottles.
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle.
Acrylonitrile butadiene styrene (ABS) is a common thermoplastic polymer. ABS is amorphous and therefore has no true melting point. it is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.
Polyvinyl chloride colloquial: polyvinyl, vinyl; PVC) is the world’s third-most widely produced synthetic plastic polymer (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year.
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent.
