Polyamide (PA), commonly referred to as nylon, is a versatile semi-crystalline thermoplastic known for its excellent wear resistance, low density, and high thermal stability.

This guide examines the properties, modifications and applications hong kong dataof PA materials, providing designers and manufacturers with detailed information on the effective use of these polymers.


Understanding PA plastic material
What is polyamide (PA)?
Polyamide, often referred to as nylon, is a class of thermoplastic polymers with repeating amide bonds (-CO-NH-). The numbers associated with PA types (such as PA 6, PA 66, PA 12, and PA 46) indicate the molecular structure of the polymer and influence its specific properties.

Properties of polyamide
Polyamide materials are renowned for their:

High wear resistance : Ideal for rolling and wear applications.
Low coefficient of friction : Improves performance in sliding applications.
High thermal stability : Suitable for high temperature environments.
Impact Resistance: Ensures durability and robustness.
Chemical Resistance: Resistant to oils, fuels and various chemicals.
Mechanical damping : Provides good vibration damping properties.
Good sliding properties: Reduces wear in dynamic applications.
Types of polyamide
PA 6 and PA 66
AP 6 : Known for its strength and flexibility. It is commonly used in extruded, injection molded and cast forms. The melting point is approximately 223°C.
PA 66: It offers slightly higher thermal resistance and stiffness than PA 6. It is widely used in technical applications as a metal substitute. The melting point is about 255°C.
PA 12
It is a semi-crystalline thermoplastic that combines low moisture absorption with excellent impact resistance and high dimensional stability. It is derived from petroleum and renewable sources.
