Introduction to PBT LG GP-2000

The PBT GP-2000 launched by LG Engineering Plastics is a general-purpose polybutylene terephthalate (material PBT) material, specially designed for injection molding, and suitable for various industrial and consumer electronics fields with high requirements for dimensional stability and electrical performance. Its low shrinkage rate, high insulation and good heat distortion temperature make it perform well in a variety of structural and electrical components.

01 | Key Characteristics of PBT GP-2000

Excellent dimensional stability: The shrinkage rates in the longitudinal and transverse directions are 1.2% and 2.1% respectively, making the structure more stable after molding.

Excellent insulation performance: Volume resistance as high as 1E16 Ω·cm, insulation strength up to 23 kV/mm, suitable for high-voltage environments.

Balanced heat resistance performance:

   The heat distortion temperature (0.45MPa) reaches 154°C

   RTI's electronic, electrical and structural dimensions all reach 140°C (UL 746B)

Impact and Mechanical Balance

   The notched impact of the cantilever beam was 3.06 kJ/m²

   The tensile strength is 54 MPa, the flexural strength is 83 MPa, and the modulus reaches 2250 MPa

02 | Application Suggestions and Potential Market Expansion for PBT GP-2000

The PBT GP-2000 is applicable to the following scenarios:

Consumer electronics and office equipment: used for printer casings, electrical connectors, plastic panels, etc.

Household appliance components: such as sewing machine parts, household control panels, etc.

Electrical frame and coil seat: Their high electrical insulation is suitable for the load-bearing structure of high-voltage components.
