PA66 GF30 is nylon 66 reinforced with 30% glass fiber. It is usually selected when an unfilled PA grade does not provide enough stiffness, creep resistance, dimensional control, or loaded-temperature performance.
Do not approve a grade from the family name alone. Property values vary by resin formulation, fiber sizing, color, conditioning state, test direction, and supplier. Use the final grade’s technical data sheet and test molded parts in the real service environment.
PA66 GF30 at a Glance
| Selection Question | Practical Answer | What to Verify |
|---|---|---|
| Why 30% glass fiber? | It provides a common balance of stiffness, strength, cost, and moldability. | Fiber orientation and weld-line load |
| Is it dimensionally stable? | More stable than unfilled PA66, but still affected by moisture, flow direction, and geometry. | Conditioned dimensions and warpage |
| Can it run at high temperature? | It generally retains stiffness better than unfilled nylon. | Grade-specific HDT, continuous-use rating, and load |
| Is it ready to mold as received? | Usually no; moisture control and supplier drying instructions are critical. | Pellet moisture at the machine |
What Is PA66 GF30?
