PBT 25% glass fiber compounds refer to a specific formulation where Polybutylene Terephthalate (PBT) is reinforced with 25% by weight of glass fibers. This combination offers a balance of mechanical strength, dimensional stability, and other enhanced properties suitable for various industrial applications.
**Mechanical Strength**: The addition of 25% glass fibers significantly increases the tensile strength, flexural strength, and modulus of elasticity of PBT. This makes it suitable for structural components that require high strength and stiffness.
**Dimensional Stability**: Glass fibers reduce the coefficient of thermal expansion of PBT, ensuring that parts maintain their shape and size over a wide range of temperatures. This dimensional stability is crucial for applications where tight tolerances are required.
**Heat Resistance**: PBT 25% glass fiber compounds exhibit improved heat resistance compared to unfilled PBT, typically retaining their mechanical properties up to around 150°C, depending on the specific formulation and processing conditions.
**Impact Resistance**: The presence of glass fibers enhances the impact resistance of PBT, making it suitable for applications where resistance to mechanical stress and impact is important.
**Applications**: Common applications for PBT 25% glass fiber compounds include automotive parts (such as under-the-hood components, brackets, and housings), electrical and electronic components (such as connectors and switches), and industrial machinery components (such as gears and pump parts). These materials are favored in industries where high-performance materials are required to withstand demanding environments and ensure long-term reliability.
