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, hightemperature 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.
