PBT 20%GF compounds, which consist of PBT reinforced with 20% glass fibers (GF), offer several key advantages:
1. **Enhanced Mechanical Strength:** The addition of 20% glass fibers significantly improves the tensile strength, stiffness, and impact resistance of PBT GF20 compared to unfilled PBT. This makes it suitable for applications requiring robust mechanical performance, such as automotive under-the-hood components, electrical connectors, and structural parts in machinery.
2. **Dimensional Stability:** PBT GF20 exhibits reduced shrinkage and excellent dimensional stability, even under varying temperatures and environmental conditions. This property ensures that parts maintain their shape and tight tolerances over time, contributing to their reliability and longevity.
3. **Improved Creep Resistance:** The presence of glass fibers minimizes creep under load, meaning that components made from PBT GF20 experience less deformation over prolonged periods of use, enhancing their durability and operational reliability.
4. **Chemical Resistance:** PBT GF20 retains PBT's inherent resistance to chemicals, oils, and solvents, making it suitable for applications in harsh industrial environments where exposure to aggressive substances is common.
5. **Electrical Properties:** It maintains good electrical insulation properties, ensuring safe and reliable performance in electrical and electronic applications.
Overall, PBT 20%GF compounds combine the excellent mechanical properties of glass fibers with the inherent advantages of PBT, making them preferred materials for demanding applications where strength, dimensional stability, and reliability are critical.
