PBT GF10 FAQ
Q1: What are the main benefits of adding glass fiber to PBT?
Adding glass fiber to PBT provides: Increased Stiffness & Strength: For more robust and load-bearing parts. Improved Dimensional Stability: Much lower shrinkage and warpage for precise dimensions. Maior resistência ao calor: Increased Heat Deflection Temperature (HDT) for use in warmer environments. Faster Cycle Times: The reinforcement accelerates crystallization, allowing faster demolding.
Q2: Is PBT GF10 suitable for connector housings?
Yes, it is one of the most common applications. PBT GF10 offers an excellent combination of high dielectric strength, good stiffness, low warpage, and fast cycling, making it an industry-standard material for a wide range of electrical connectors, sockets, and switch housings.
Q3: How should PBT GF10 be processed?
For best results: Secagem: Essential. Dry at 120°C for 3-4 hours to avoid hydrolysis (property degradation due to moisture). Temperatura de fusão: 240-260°C is typical. Avoid excessive temperatures and residence time. Mold Temperature: 60-80°C is recommended for optimal crystallinity and surface gloss. Fast Injection: Utilize its fast-crystallizing nature with relatively high injection speeds.
