PBT (Polybutylene terephthalate)

What is PBT (Polybutylene Terephthalate)?

PBT is often used in electronics, the automotive industry and technical components where wear resistance and chemical resistance are important factors.

Important properties of PBT

• High mechanical strength – Stiff and durable, making it ideal for technical parts.
• Excellent electrical insulation – Suitable for electronic and electrical components.
• High chemical resistance – Resistant to oils, greases, fuels and many industrial chemicals.
• Good heat resistance – Can be used in temperatures up to approximately 150–170°C depending on variant.
• Resistant to moisture – Absorbs minimal water and maintains its mechanical properties.
• High abrasion resistance – Suitable for applications with moving parts.
• Flame retardant properties – Can be modified to meet fire safety requirements.
• Easy to injection mold and process – Used in mass production of technical components.

Different types of PBT (Polybutylene Terephthalate) and their uses

• Pure PBT – Used in electronics and technical details.
• Glass fiber reinforced PBT – Higher stiffness and better dimensional stability, used in automotive and industrial components.
• Flame retardant PBT – Modified to meet fire safety standards, used in electrical and electronic applications.
• UV-stabilized PBT – Increased weather resistance for outdoor applications.

How do we use PBT (Polybutylene Terephthalate) in our production?

We use PBT in high-performance technical applications where strength, chemical resistance and electrical insulation are crucial.

Some of the most common uses are:

• Electronics and electrical components – PBT is used in connectors, junction boxes and circuit board housings.
• Automotive industry – Used in sensors, wiring harnesses, headlight brackets and engine components.
• Industrial machine parts – Glass fiber reinforced PBT is used in gears, bearings and other durable components.
• Household appliances – PBT is used in electrical components in coffee machines, hair dryers and white goods.
• Construction and civil engineering – Used in insulating materials for electrical installations.

Why do we choose PBT?

PBT is an optimal material for applications where strength, electrical insulation and chemical resistance are required. It is particularly useful in the automotive and electronics industries due to its high dimensional stability and good thermal properties.

To optimize PBT for specific needs, it can be modified with:

• Fiberglass reinforcement – For increased rigidity and strength.
• Flame retardant – To meet fire safety requirements.
• UV stabilizers – For increased lifespan when used outdoors.

In summary, PBT is one of the most widely used engineering plastic materials in electronics, automotive and industrial applications.
