PA66 is the abbreviation for polymer compound 66 or synthetic resin

PA66 is the abbreviation for polymer compound 66 or synthetic resin. It is made from two monomers, hexamethylenediamine and adipic acid, which are chemically combined to form long chains of repeating units. The current market is recording a high level of PA66 application and is constantly increasing. Currently, PA66 is divided into a variety of different groups based on compound ratio and performance. The following article will provide useful information about common types of PA66 and how to choose a suitable PA66 line for your upcoming project. 

1. Six types of PA66

PA66 is divided into a variety of different groups based on compound ratio and performance

PA66 is divided into a variety of different groups based on compound ratio and performance

1.1. PA66 GF60

Corresponding to the name, PA66 GF60 is a combination of PA66 and 60% glass fiber. At this ratio, PA66 GF60 is strongly enhanced with inherent properties such as hardness, durability, and good elasticity. In addition, PA66 GF60 also demonstrates excellent properties when possessing heat resistance and dimensional stability when operating in harsh environments.

1.2. PA66 GF50

PP66 GF50 is also the result of combining PA66 with 50% glass fiber. This combination also aims to improve the properties of the original material. They also possess basic properties such as strength, flexibility, and good strength. However, in PP66 GF50 stands out with its higher thermal stability and improved thermal stability compared to similar products. Specifically, PP66 GF50 maintains an excellent anti-warping rate even in environments operating under high loads at high temperatures (up to 130°C).

1.3. PA66 GF30

PA66 GF30 is a combination of PA66 and 30% glass fiber (GF 30%). This combination gives the material perfectly improved properties. They possess higher durability, creep resistance, and hardness. In addition, PA66 GF30 possesses numerous excellent mechanical properties and ideal dimensional stability. PA66 GF30 is one of the top choices for applications requiring elasticity, good heat resistance and long-term load balance. The additive of PA66 GF30 is inherently black and enhances long-term external UV protection. Some common applications of PA66 GF30 include car covers, engine covers and some exterior designs.

1.4. PA66 GF35

35% glass fiber has excellent durability and thermal stability combined with PA66, we get PA66 GF35. This material is also considered to have superior hardness than PA66 GF30. Thanks to its outstanding hardness, PA66 GF35 is always the ideal choice for mechanical engineering and aerospace applications. In addition, when using PA66 GF35 plastic, we can choose the size flexibly thanks to its ability to adapt well to extremely diverse extrusion methods into sheets and bars.

1.5. PA66 GF15

The combination of PA66 and 15% glass fiber brings to the manufacturing industry a new material called PA66 GF15. This is a material commonly used in the process of creating thermoplastic structural foam (TSF). The material PA66 GF15 is well adapted to the plastic injection molding process in the production line. This is one of the materials that is considered quite durable and hard but not as strong as materials containing a higher percentage of glass.

1.6. Flame retardant PA66

Flame retardant PA66 plastic is a combination of PA66 plastic and flame retardant. This is a combination that gives the material great properties. Among them, the most outstanding feature of fireproof PA66 is its ability to operate durably in high temperature environments. The reason is thanks to flame retardant additives that have the ability to prevent polymer materials from igniting or inhibit the flame propagation process of the material. This feature makes PA66 one of the materials with impressive performance in harsh thermal environments.

  • Based on operating environment

Relying on the operating environment is one of the indispensable things to help us choose the right PA66. Factors to consider such as frequency of impact, temperature requirements, operating environment indoors or outdoors or even underground

  • Based on production method

Products can be manufactured and shaped according to many different processes and specifications. To choose the right PA66, we need to consider the product manufacturing process such as injection molding, extrusion, 3D printing, molding, etc. Depending on each production process, we can consider choosing the compatible PA66 line. This contributes significantly to limiting damage and waste of raw materials during the production process.

  • Based on performance requirements

To properly determine suitable PA66, we need to determine product performance requirements. Different applications will have different performance requirements such as hardness, elasticity, ductility, heat resistance, and abrasion resistance. These performance requirements are extremely diverse depending on each production plan. Therefore, careful consideration of the product performance requirements will help us choose PA66 that is suitable for the project.
