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.
| 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 |
| Property | Typical Value |
|---|---|
| Density | 1.12 – 1.15 g/cm³ |
| Tensile Strength | 70 – 90 MPa |
| Melting Point | 215°C (PA6), 255°C (PA66) |
| Impact Resistance | High |
| Abrasion Resistance | Excellent |
| Water Absorption | Moderate to High |
| Electrical Insulation | Good (but drops with moisture) |
