PA6 GF30 (30% Glass Fiber Reinforced Polyamide 6) is a high-strength engineering plastic offering excellent mechanical strength, stiffness, wear resistance, and dimensional stability. Reinforced with 30% glass fibers, this grade is ideal for load-bearing components, precision machined parts, and industrial applications exposed to continuous stress, abrasion, and high mechanical loads.
What is PA6 GF30?
PA6 GF30 (30% Glass Fiber Reinforced Polyamide 6) is one of the most robust and
high-performance grades within the polyamide family. By reinforcing PA6 with 30% glass fibers,
this material achieves significantly improved mechanical strength, stiffness, dimensional
stability, and thermal resistance compared to unfilled polyamides.
PA6 GF30 is specifically designed for components subjected to high loads, continuous stress,
and demanding operating conditions. It is widely used in mechanical engineering, automotive,
and heavy industrial equipment.
The presence of glass fibers increases the elastic modulus, wear resistance, creep resistance,
and long-term load-bearing capability, making this grade an excellent choice for precision
components exposed to vibration, force, and tight dimensional tolerances.
Key engineering properties of PA6 GF30
1. Very high mechanical strength
Glass fiber reinforcement significantly improves tensile, flexural, and compressive strength.
PA6 GF30 performs reliably in components subjected to heavy loads and continuous mechanical stress.
2. High stiffness and rigidity
Compared to standard PA6, this grade exhibits much lower deformation under load and superior
dimensional stability.
3. Excellent wear resistance
PA6 GF30 is well suited for applications involving friction, contact, and abrasive operating
conditions.
4. Superior dimensional stability
Glass fibers reduce dimensional changes caused by moisture absorption, temperature fluctuations,
and mechanical loading.
5. Improved thermal resistance
PA6 GF30 maintains stable mechanical performance at elevated temperatures compared to PA6 and
standard PA66 grades.
6. High creep resistance
One of the key advantages of PA6 GF30 is its resistance to deformation under constant load over
long periods of time.
Typical applications of PA6 GF30
- Gears and power transmission components under high load
- Bushings, bearings, and pressure-resistant spacers
- Precision CNC-machined components with tight tolerances
- Heavy-duty wear plates, guides, and sliding rails
- Structural parts for industrial machinery
- Components exposed to vibration and mechanical shock
- Wear-resistant parts in production and assembly lines
