What is PBT Plastic Material - 2002-2

As the plastics industry continues to evolve towards high performance and versatility, polybutylene terephthalate (PBT plastic material) has gained wide application in the electrical and electronic, automotive and industrial sectors due to its excellent overall performance. PBT 2002-2 from Celanese is a typical general-purpose pellet material with non-reinforced, internally lubricated properties to meet diversified injection moulding needs.

PBT 2002-2 adopts a granular form and supports the injection molding process. The flame retardant grade of the material is HB. It is equipped with lubricants and mold release agents, which makes the product molding process more stable and ensures a high surface finish. It has medium fluidity and is suitable for injection molded parts with various complex structures, especially for application scenarios that require internal lubrication and balanced processing performance.

01 | Analysis of The Core Performance of PBT Plastic Material

Balance liquidity and processability

Celanese PBT 2002-2 has a good flow balance, taking into account the performance requirements of both the filling and holding pressure stages, ensuring a stable injection molding cycle and accurate finished product dimensions.

Excellent Electrical Insulation

The material has an electrical strength of 30KV/mm and a volume resistance of 1×10^15 Ω.cm, making it suitable for parts with stringent insulation requirements in electronics and electrical appliances.

Stable and reliable thermal performance

Its heat distortion temperature is around 150℃ (0.45MPa load), and its Vicat softening temperature reaches 190℃, which ensures worry-free long-term use under moderate thermal load environment.

The mechanical properties are moderate and meet general requirements

The elongation at break reaches 50%, the tensile strength is 60MPa, demonstrating certain toughness and good strength balance, and is suitable for various general structural components.

Structurally stable, meets basic flame retardant needs

PBT 2002-2 has low shrinkage and good dimensional stability, suitable for precision injection moulding; HB-rated flame retardancy, suitable for general electronics and structural component applications.

02 | PBT Plastic Material Typical Application Scenarios

Electronic and electrical components

Suitable for relay housings, power plugs, etc. Internal lubrication characteristics reduce friction and extend service life.

Automotive interior and non-structural parts

Suitable for the manufacture of interior parts requiring a certain degree of rigidity and aesthetics, flame retardant performance to meet the basic safety standards.

General industrial parts

Such as connector blocks, shells, etc., to meet the physical and electrical requirements of daily industrial applications.

03 | Comparative Advantages with Other PBT Plastic Materials

Compared with reinforced PBT, PBT 2002-2 does not contain glass fibre, but has better surface finish and flow properties due to its internal lubrication and no filler characteristics. It is suitable for precision moulds and applications with high surface requirements. In addition, its low water absorption and stable electrical properties have irreplaceable advantages in the manufacture of certain electronic components.
