1. What is PBT material?

PBT is a semi-crystalline thermoplastic polyester with excellent mechanical strength, electrical insulation and chemical corrosion resistance. It has good processing performance and is suitable for various molding methods such as injection molding, extrusion and blow molding. In recent years, with the innovation of formulas, the flame retardancy, dimensional stability and surface finish of PBT have been significantly improved, meeting the strict requirements of modern manufacturing processes.

2. Procurement Focus: Performance and Processing

Dimensional Stability: Low shrinkage after moulding, suitable for precision part manufacturing. 

Chemical Resistance and High-Temperature Resistance: Suitable for fuel systems, electrical insulation components, and high-temperature working environments.

Low Water Absorption: Ensures mechanical and electrical properties in humid environments. 

Processing Flexibility: Suitable for injection molding and extrusion, with rapid crystallization, shortening production cycles.

Modification Options: Glass fiber reinforcement, flame retardant, or wear-resistant grades are available to enhance part durability.

💡 Buyer’s Tip: Go beyond the datasheet—match PBT’s properties to the intended product design and processing setup to prevent costly production issues.

3. Typical applications

Автомобильная промышленность: Sensor housings, lighting components, connectors, and handles.

Electrical and Electronics: Sockets, switches, relay housings, and coil bobbins.

Industrial equipment: Pump housings, gears, and conveying system components.

Consumer Goods: Appliance housings, power tool housings, etc.

💡 Buyer’s Tip: Different application environments require different grades of PBT. For example, high-temperature or flame-retardant requirements should prioritise corresponding modified products.

4. Current market trends

Stable growth: The global PBT market is expected to grow at an average annual rate of approximately 6% over the next decade, with automotive lightweighting and the demand for electronic devices being the main drivers.

Electric vehicle assistance: The requirements for heat-resistant and insulating materials in EVs have increased, leading to the use of high-performance PBTS. 

Environmental protection trend: The development of bio-based and recyclable PBT is gradually increasing, which is suitable for enterprises' green procurement strategies.

Regional characteristics: Asia (especially China) accounts for over 60% of global production and consumption, and price fluctuations are influenced by seasons and raw materials.

💡 Procurement Reference: Focus on suppliers' production capacity stability and long-term delivery capabilities to avoid disruptions to production plans caused by short-term price fluctuations.

5. Key Considerations for PBT Material Selection

Performance and Specification Matching: Different grades of PBT vary in flame retardancy, dimensional stability, and surface quality. For example, BASF Ultradur B4335G3 HR HSP offers excellent hydrolytic stability and flowability, making it suitable for producing thin-walled parts.

Supply Chain Stability: The global PBT market has recently been impacted by supply chain uncertainties and trade frictions, resulting in significant price fluctuations. For instance, in July 2025, the PBT market in China and the United States saw price reductions due to excess inventory and weak downstream demand.

Cost Control and Procurement Strategy: Market analysis indicates that PBT prices are expected to stabilise or decline in 2025, primarily due to weak demand and increased imports from Asia. Approximately 40% of global PBT is used in the automotive market, and the downturn in the automotive industry will impact supply and prices.

6. How to Select Suppliers

When selecting reliable PBT suppliers, consider not only price but also:

  ・Stable Supply Capacity: Ensure timely delivery to minimise production interruptions.

  ・Technical Support: Provide material selection, processing parameters, and application recommendations.

  ・Batch Consistency: Ensure consistent performance to reduce rework and waste.

  ・Transparent Market Information: Timely provide price trends, inventory, and delivery schedule information.

For example, Juyuan, as a professional PBT raw material trader, offers global procurement services, technical consulting, and customised logistics solutions to help buyers mitigate risks and optimise costs.
