Glass Fiber Reinforced Structure Explanation 

Glass fiber-reinforced PBT combines the intrinsic properties of polybutylene terephthalate (PBT) with the strength and stiffness of glass fibers. These fibers significantly improve the material’s tensile strength, impact resistance, and dimensional stability. The fibers provide reinforcement at the microscopic level, improving performance under stress and in high-temperature environments.


Material Advantages

PBTGF30 delivers superior strength, heat resistance, and dimensional stability.

High Rigidity: The incorporation of glass fibers in PBT significantly increases its modulus of elasticity, making it an ideal material for structural components where high stiffness is required. This ensures the product maintains its shape and integrity under mechanical stress.

High Impact Resistance: The glass fiber reinforcement enhances the impact strength, making it highly durable and capable of withstanding sudden loads or impacts, which is particularly useful in automotive and electrical applications.

Excellent Thermal Stability: With superior heat resistance, PBT GF30 can perform effectively in high-temperature environments, up to 200°C, making it a reliable choice for automotive components such as wiper systems and connectors.

Good Electrical Insulation: This material excels in electrical performance, offering high insulation resistance and low dielectric loss, which is critical for electrical components.
