PBT GF20 FAQ
Q1: When should I choose PBT GF20 over GF10?
Choose PBT GF20 when your application requires higher mechanical strength, greater rigidity, and better thermal resistance than GF10 can provide, but still demands excellent dimensional stability, good surface finish, and strong electrical insulation. It‘s ideal for more structurally demanding electrical parts.
Q2: Can PBT GF20 be used for automotive components?
물론입니다. 다음과 같은 조합이 있습니다. heat resistance (under-the-hood capable), good chemical resistance to fuels and oils, dimensional stability, and electrical properties makes it suitable for various automotive applications such as sensor housings, connectors, and ignition system components.
Q3: Does the higher fiber content affect the surface finish?
With proper processing, PBT GF20 can achieve a very good surface finish. Key factors include using a sufficiently high mold temperature (70-90°C) to promote surface gloss and ensuring gates are properly sized and positioned to minimize visible weld lines.
