List of synthetic polymers
Some familiar household synthetic polymers include:
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]
Inorganic polymers
- Polysiloxane
- Polyphosphazene
- Polyborazyline
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)
- Polyvinyl chloride (PVC)
- Polystyrene (PS)
- Nylon, nylon 6, nylon 6,6
- Teflon(Polytetrafluoroethylene)
- Thermoplastic polyurethanes(TPU)
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, 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 | plastic cutlery
| |
Polytetrafluoroethylene | PTFE | Very low coefficient of friction, excellent dielectric properties, chemically inert |
Low friction 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 | gaskets etc.
|
