Polymer Properties:

• Base Material: Polyamide 66 (PA66)
• Reinforcement: 35% Short Glass Fiber
• Key Benefits:
  
  • High Rigidity and Strength: The 35% glass fiber reinforcement provides a high modulus of elasticity and tensile strength. 
  • Excellent Heat Resistance: PA66 has a high melting point, and the glass fiber reinforcement further improves its heat deflection temperature. 
  • Good Chemical Resistance: PA66 offers good resistance to many chemicals, including oils, greases, and solvents.
  • Dimensional Stability: The glass fibers help to minimize thermal expansion and shrinkage, leading to parts with excellent dimensional stability.
