Complete Guide on PA (Polyamide): Types, Grades, Applications, Processing & Global Market
1. What is PA (Polyamide)? | Full Form and Definition
PA, commonly known as Polyamide or Nylon, is a family of synthetic polymers with high mechanical strength, heat resistance, and chemical durability. The most widely used types are Nylon 6 and Nylon 66.
2. Types and Grades of Polyamide
| Type | Features | Applications |
|---|---|---|
| PA6 | Good toughness, easy processing | Automotive, textiles, injection molding |
| PA66 | Higher melting point & stiffness | Gears, electrical parts, under-the-hood parts |
| PA11 / PA12 | Flexible, high impact, low moisture | Tubing, fuel lines, medical devices |
| Glass-Filled PA | Enhanced strength and stiffness | Structural and automotive components |
| Flame Retardant PA | Fire-safe formulations | Electrical and electronics |
