Nylon is a versatile thermoplastic known for its high thermostability, stiffness, hardness, and toughness. It can withstand temperatures ranging from -40 °C to +100 °C and offers excellent mechanical properties. However, to maintain these properties, nylon must be conditioned after annealing, and it tends to absorb moisture over time, which can affect its mechanical and dimensional stability.
Properties of Nylon
Nylon has several key properties that make it suitable for a wide range of applications:
- High strength and stiffness: Nylon provides high mechanical strength, making it suitable for demanding applications.
- High impact and notching impact strength: Nylon offers good resistance to impact and notching, providing durability and resilience.
- High heat deflection temperature: Nylon can withstand high temperatures without deforming or losing its properties.
- Good damping ability: Nylon has excellent damping properties, allowing it to absorb shock and vibration effectively.
- Good glide and sliding ability: Nylon’s low friction allows for smooth sliding and movement in various applications.
- Good chemical stability against organic solvents and fuels: Nylon resists a range of organic solvents and fuels, ensuring durability in challenging environments.
- Size alteration by humidity absorption: Nylon’s tendency to absorb moisture can lead to size changes, affecting its dimensional stability and mechanical properties.
- Dimension stability, electrical, and mechanical properties may be affected by absorbing moisture or water: Nylon’s moisture absorption can impact its performance, requiring proper conditioning and maintenance.
Applications of Nylon
Due to its unique combination of properties, nylon is used in various industries and applications:
- Bearing parts: Nylon’s good sliding properties and high strength make it ideal for bearing components.
