Enhanced Strength & Rigidity: Glass Fiber Reinforced PBT (GF-PBT)

           Modified PBT with 15-50% glass fiber's advantages and applications

1.Advantages

Incorporating glass fibers (typically 15-50%) dramatically boosts PBT's mechanical properties. 

Tensile strength, flexural modulus (stiffness), and creep resistance are significantly increased, 

often doubling or tripling compared to unfilled PBT. This allows thinner wall designs while maintaining structural integrity 

under load. Dimensional stability improves, reducing warpage and shrinkage, crucial for precision parts. 

Heat deflection temperature (HDT) also rises substantially, enabling use at higher continuous operating temperatures.

2.Applications

Essential for high-strength components in circuit breakers (housings, arc chutes, operating mechanisms),

LED lighting(reflectors, heat sink housings, robust sockets), automotive connectors, sensors, and under-the-hood parts 

(throttle bodies, ignition components). 

Widely used in power tool housings, appliance gears, and pump impellers demanding stiffness and thermal stability.
