PA6 GF30 Rod (30% Glass Fiber Reinforced Polyamide) is a high-performance engineering plastic rod with excellent mechanical strength, stiffness, wear resistance, and dimensional stability. This grade is widely used for CNC-machined components, bushings, gears, bearings, and load-bearing industrial parts exposed to continuous stress and heavy mechanical loads.
What is PA6 GF30 Rod?
PA6 GF30 Rod (30% Glass Fiber Reinforced Polyamide) is a reinforced engineering-grade
polyamide produced by adding 30% glass fibers to PA6. This reinforcement significantly improves
mechanical strength, stiffness, wear resistance, dimensional stability, and load-bearing
capacity compared to unfilled PA6 rods.
PA6 GF30 Rod is one of the most widely used materials for manufacturing industrial components
subjected to high loads, continuous stress, impact, and abrasive operating conditions. It is
commonly used across mechanical engineering, automotive, industrial equipment, robotics,
packaging machinery, and CNC machining applications.
The popularity of PA6 GF30 Rod is driven by its unique balance of strength, stability,
service life, and precise machinability, placing it well above virgin polyamide rods
in demanding industrial environments.
Key engineering advantages of PA6 GF30 Rod
1. Very high mechanical strength
The tensile strength of PA6 GF30 Rod can reach values of up to approximately
170 MPa, making it ideal for components subjected to heavy loads and continuous
mechanical stress. Glass fiber reinforcement also improves compressive and flexural strength.
2. Excellent dimensional stability
Unlike unfilled polyamide, PA6 GF30 exhibits minimal deformation caused by moisture
absorption and mechanical loading. This property is essential for CNC-machined parts
requiring tight tolerances.
3. Very high wear resistance
PA6 GF30 Rod is highly suitable for sliding, rotating, and contact-intensive applications.
Its wear resistance is significantly higher than that of virgin PA6.
4. Increased stiffness and rigidity
Glass fiber reinforcement increases stiffness, allowing components manufactured from
PA6 GF30 to resist bending, buckling, and vibration under load.
5. Suitable thermal resistance
PA6 GF30 Rod provides stable performance within a typical service temperature range of
-30°C to +120°C, making it suitable for medium to high temperature industrial
applications.
6. Precision CNC machinability
Good chip formation, controlled tool response, and dimensional stability make PA6 GF30
Rod one of the best materials for precision CNC machining.
7. Good chemical resistance
This grade offers good resistance to oils, fuels, greases, industrial lubricants, and many
commonly used industrial chemicals.
