Polybutylene terephthalate (PBT) is a thermoplastic engineering
polymer, that is used as an insulator in the electrical and
electronics industries. It is a thermoplastic (semi-)crystalline
polymer, and a type of polyester. PBT is resistant to solvents,
shrinks very little during forming, is mechanically strong,
heat-resistant up to **0 °C (or **0 °C with glass-fibre
reinforcement) and can be treated with flame retardants to make it
noncombustible.
PBT is closely related to other thermoplastic polyesters. Compared
to PET (polyethylene terephthalate), PBT has slightly lower
strength and rigidity, slightly better impact resistance, and a
slightly lower glass transition temperature. PBT and PET are
sensitive to hot water above *0 °C (**0 °F). PBT and PET need UV
protection if used outdoors, and most grades of these polyesters
are flammable, although additives can be used to improve both UV
and flammability properties.
Application
Polybutylene terephthalate is used for housings in electrical
engineering, but also in automotive construction as plug connectors
and in households for example in showerheads or irons. It is also
found processed into fibers in toothbrushes. It is used in the
keycaps of some mechanical keyboards because of its resistance to
wear.
