1. PBT and ABS plastic - An overview
Before delving into the differences, let's briefly overview PBT vs ABS plastics. PBT is a semi-crystalline thermoplastic polyester with excellent mechanical, electrical, and thermal properties. It is known for its high strength, stiffness, and dimensional stability. On the other hand, ABS is a terpolymer composed of Acrylonitrile, Butadiene, and Styrene. ABS offers a unique combination of toughness, impact resistance, and good processability.
Understanding the dissimilarities between these two materials is essential for choosing the appropriate plastic for specific applications, considering mechanical requirements, thermal stability, chemical resistance, and electrical properties.

2. PBT vs ABS - What are the differences?
a. Composition and properties of PBT
PBT derives from the condensation polymerization of terephthalic acid or dimethyl terephthalate with 1,4-butanediol. Its highly crystalline structure results in excellent dimensional stability and low creep. PBT also exhibits good resistance to chemicals, oils, and solvents, making it suitable for various applications.
Regarding mechanical properties, PBT offers high tensile strength, stiffness, and impact resistance. It retains its mechanical integrity at elevated temperatures and demonstrates good fatigue resistance. PBT also has excellent electrical insulating properties, making it an ideal choice for electrical and electronic components.
b. Composition and properties of ABS
ABS is a copolymer comprising three monomers: Acrylonitrile, Butadiene, and Styrene. This combination provides ABS with a balance of properties, making it versatile in many applications. The acrylonitrile component enhances chemical and thermal resistance, while butadiene imparts impact strength and flexibility. The styrene component contributes to rigidity and processability.
ABS exhibits good dimensional stability and impact resistance and can be easily molded and fabricated. Its excellent surface finish and resistance to scratches and abrasion also characterize it. ABS performs well across various temperatures and demonstrates good electrical insulating properties.
c. Key differentiating factors between PBT vs ABS
When comparing PBT vs ABS, several vital factors differentiate them:
- Mechanical properties: PBT offers higher tensile strength and stiffness compared to ABS. However, ABS excels in impact resistance and flexibility, making it more suitable for demanding applications.
- Thermal properties: PBT exhibits better thermal stability and dimensional accuracy over a wide temperature range. ABS has a lower heat deflection temperature but can withstand lower temperatures without becoming brittle.
- Chemical resistance: PBT demonstrates superior resistance to chemicals, oils, and solvents compared to ABS. ABS has moderate chemical resistance but may be prone to degradation in the presence of certain substances.
- Electrical properties: Both PBT vs ABS exhibit good electrical insulating properties. However, PBT has higher dielectric strength and lower dielectric loss, making it preferable for applications requiring excellent electrical performance.
Considering these differentiating factors is crucial in selecting the appropriate material based on the specific requirements of the application at hand.

3. PBT vs ABS: Which one is better?
The choice between PBT vs ABS depends on various factors, including the specific application, environmental conditions, desired properties, and cost considerations.
PBT's strengths are its high strength, stiffness, dimensional stability, and chemical resistance. Often, people prefer it in applications such as automotive parts, electrical connectors, and appliances where these properties are critical. However, it is essential to note that PBT may be more expensive than ABS.
ABS, on the other hand, excels in impact resistance, toughness, and processability. It finds applications in various industries, including automotive components, consumer goods, toys, and electronic enclosures. ABS is generally more cost-effective than PBT, making it a popular choice when balancing performance and affordability is crucial.
Ultimately, the selection between PBT vs ABS should base them on a comprehensive evaluation of the specific requirements, including mechanical, thermal, chemical, and electrical properties and budget considerations.
An example of the choice between PBT vs ABS can be seen in electronic enclosure manufacturing. PBT may be preferred if the section requires high strength and dimensional stability. However, if impact resistance and affordability are more critical factors, ABS would be a better choice. The decision would depend on the specific requirements and budget of the project.
