PA Material, commonly known as nylon, is short for Polyamide in English.

It refers to a class of high polymer compounds with amide groups in their main chain repeating units, and it's a widely used engineering plastic.

Here are the characteristics of PA material:

• Tough, wear-resistant, oil-resistant, water-resistant, and resistant to enzymes, but it has high water absorption.

• It has a high melting point, and its thermal stability can be significantly improved through modification, with a heat distortion temperature of up to 250°C.

• 
  

• Its electrical properties are good under dry conditions and can be used as insulating materials.

• It's particularly good as a high-frequency insulation material, but it's prone to water and moisture absorption, which reduces its insulation performance.

• 
  

• It possesses excellent mechanical properties, good impact strength and tensile strength, good friction resistance, and dimensional stability.

• It has abundant raw materials, various types, low prices, and is easy to recycle.

• 
  

• PA material has good resistance to frictional wear, self-lubricating properties (water can be used as a lubricant), and fatigue resistance, which is one of the important reasons for its wide application as an engineering plastic.

Polyamide is non-toxic, lightweight, has excellent mechanical strength, wear resistance, and good corrosion resistance, so it is widely used in industrial manufacturing of bearings, gears, pump blades, and other parts.

PA material can be widely used in fibers, engineering plastics, and many other fields, such as clothing, outdoor equipment, household items, automotive parts, electronic devices, mechanical parts, etc.
