List of synthetic polymers

Some familiar household synthetic polymers include: Nylons in textiles and fabrics, Teflon in non-stick pans, Bakelite for electrical switches, polyvinyl chloride (PVC) in pipes, etc. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate. The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes.^[1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered. They are however expensive when compared to the synthetic polymers.^[2]

IUPAC definition

Artificial polymer: Man-made polymer that is not a biopolymer.

Note 1: Artificial polymer should also be used in the case of chemically
modified biopolymers.

Note 2: Biochemists are now capable of synthesizing copies of biopolymers
that should be named Synthetic biopolymer to make a distinction
with true biopolymers.

Note 3: Genetic engineering is now capable of generating non-natural analogues
of biopolymers that should be referred to as artificial biopolymers, e.g.,
artificial protein, artificial polynucleotide, etc.^[3]

Organic polymers

The eight most common types of synthetic organic polymers, which are commonly found in households are:

• Low-density polyethylene (LDPE)
• High-density polyethylene (HDPE)
• Polypropylene (PP)
• Polyethylene (PE)
• Polyvinyl chloride (PVC)
• Polystyrene (PS)
• formaldehyde.
• Nylon, nylon 6, nylon 6,6
• Teflon (Polytetrafluoroethylene)
• Thermoplastic polyurethanes (TPU)

List of some addition polymers and their uses

	Polymer	Abbreviation	Properties	Uses
	Low-density polyethylene	LDPE	Chemically inert, flexible, insulator	Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six-pack rings, etc.
	High-density polyethylene	HDPE	Inert, thermally stable, tough and high tensile strength	Bottles, pipes, inner insulation (dielectric) of coax cable (see also PTFE), plastic bags, etc.
	Polypropylene	PP	Resistant to acids and alkalies, High tensile strength	Auto parts, industrial fibers, food containers, liner in bags, dishware and as a wrapping material for textiles and food
	Polystyrene (thermocole)	PS	Thermal insulator. Properties depends on the form, expanded form is tough and rigid	Petri dishes, CD case, plastic cutlery
	Polytetrafluoroethylene	PTFE	Very low coefficient of friction, excellent dielectric properties, chemically inert	Low friction bearings, non-stick pans, inner insulation (dielectric) of coax cable (see also HDPE), coating against chemical attack etc.
	Polyvinyl chloride	PVC	Insulator, flame retardant, chemically inert	Pipe (mainly draining), fencing, lawn chairs, hand-bags, curtain clothes, non-food bottles, raincoats, toys, vinyl flooring, electrical installation insulations, etc.
	Polychlorotrifluoroethylene	PCTFE	Stable to heat and thermal attacks, high tensile strength and non wetting	valves, seals, gaskets etc.
