Polymer Properties:

• Base Material: Polyamide 66 (PA66)
• Reinforcement: 20%  Glass Fiber
• Key Features and Properties:
  • High Mechanical Strength and Stiffness: 20% glass fiber reinforcement significantly improves mechanical properties compared to unreinforced PA66.
  • Excellent Thermal and Hydrolytic Stability: The “HSL” in the name stands for “Heat Stable, Low Speed.”
  • Good Dimensional Stability: Glass fiber reinforcement helps minimize shrinkage and warpage during the molding process, resulting in parts with excellent dimensional stability.
  • Chemical Resistance: Zytel 70G20HSL exhibits good resistance to a wide range of chemicals( eg:oils, fuels, and greases),which is critical for automotive and industrial components.
  • Easy Processing: Despite its reinforcements, this grade is renowned for its excellent processability, enabling efficient molding of complex parts with a superior surface finish.

Applications:

1. Automotive: Used for under – hood parts like radiator end – tanks and engine brackets. Also applied in transmission components due to its strength and heat resistance.
2. Electronics: Applied in electrical connectors and housings. Its properties ensure insulation, protection, and dimensional stability.
3. Industrial Equipment: Utilized for manufacturing gears, bearings, etc. It provides strength, durability, and wear – resistance for long – term machinery operation.
