PA11 GF20 FAQ
Q1: When should I choose PA11 GF20 over GF10?
Choose PA11 GF20 when your application requires significantly higher rigidity, tensile strength, and thermal resistance than GF10 can provide, but must still retain very good impact strength and superior chemical resistance. It is the logical choice for structurally more demanding parts in corrosive or demanding environments.
Q2: Is PA11 GF20 suitable for gears in chemical processing equipment?
Yes, it is an excellent candidate. Its combination of good stiffness, low moisture absorption (minimal swelling), inherent lubricity, and outstanding chemical resistance makes it suitable for gears, bearings, and bushings in equipment that may be exposed to corrosive chemicals or wash-downs.
Q3: Does the higher fiber content affect the surface finish compared to GF10?
The surface will show a more pronounced glass fiber pattern compared to GF10. While it can achieve a functional technical finish, for high-gloss aesthetic surfaces, painting or texturing is recommended. For the best possible surface in a 20% filled grade, discuss surface-modified options with your supplier.
