What is Polybutylene Terephthalate (PBT)?
Polybutylene Terephthalate is a semi-crystalline
engineering thermoplastic. It shares similar
properties and composition with polybutylene
terephthalate granules. It belongs to the
polyester family of PBT granules(VALOX 420SEO,
VALOX DR51, VALOX 357X, etc). The
polycondensation or polymethyl terephthalate of
terephthalic acid with 1,4-butanediol is the
process that produces PBT. Special catalysts are
used. Due to its broad range of uses, PBT natural
has attracted commercial attention.

What is Polybutylene Terephthalate (PBT)?

• There are many grades of PBT that are ideal for
  injection molding. These are
• Reinforced
• Filled
• Impact-modified and
• Flame-retardant
• Both unreinforced PBT and reinforced versions of
  flame-retardant Polybutylene Terephthalate are
  available. Glass-reinforced VALOX PBT resin has a
  two to threefold increase in its tensile and
  flexural strengths, as well as its moduli when
  compared to non-reinforced ones.

Properties of PBT

• SABIC PBT resins have excellent electrical and
  mechanical properties. Below are the main
  properties of the polyester material.
• It is extremely stain resistant and has great
  machining properties.
• It allows for efficient material use to reduce
  weight and costs.
• It has excellent short-term mechanical
  properties such as high strength and toughness.
• It has good creep resistance, dimension
  stability, and low moisture absorption.
• It is resistant to thermal stress and chemical
  environments, especially in automotive underhood
  applications.

Properties of PBT
VALOX PBT dana has high heat deflection
temperatures, high-temperature index ratings, and
high heat resistance help components withstand
both short-term thermal excursions as well as
long-term heat exposure. Protective coating for
electronic and electrical components is
Polybutylene Terephthalate. It has a high level
of electrical resistance and high dielectric
force that protects against power circuitry
leakage. Low dielectric losses reduce energy
absorption for high-frequency electronic
applications.
