What is PA66 GF60?

60% glass fibre reinforced polyamide 66 (PA66) is a type of plastic that has been reinforced with glass fibres. This reinforcement can improve the strength, stiffness, and durability of the material. Fasteners made of 60% glass fibre reinforced PA66 are likely to be stronger and more durable than those made of unreinforced PA66 or other types of plastic. They may also have improved resistance to temperature, chemical, and other types of stress.

PA66 is a type of polyamide, which is a polymer that is formed by the polymerization of a diamine and a dicarboxylic acid. PA66 is known for its high strength, stiffness, and toughness, as well as its good fatigue resistance and low creep. It is commonly used in automotive, electrical, and electronic applications, as well as in the aerospace and defence industries.

The use of glass fibres as reinforcement can further improve the properties of PA66. Glass fibres are strong and stiff, and they can help to increase the overall strength and stiffness of the material. They also have good resistance to temperature, chemicals, and other types of stress. The addition of glass fibres to PA66 can result in a material that is stronger, stiffer, and more durable than unreinforced PA66.

Fasteners made of 60% glass fibre reinforced PA66 are likely to be used in applications where strength and durability are important. They may be used in a variety of industries, including automotive, aerospace, and defence.

Common Applications

PA66 GF30 can be used to replace metallic components. Examples are given below:

Mitigating galvanic corrosion: Galvanic corrosion is a type of corrosion that occurs when two different metals are in contact with each other in the presence of an electrolyte. The more noble metal is protected from corrosion, while the less noble metal is corroded. In flange applications, the use of PA66 GF60 can help to mitigate galvanic corrosion by replacing the metal flange with a non-metallic material. This can help to prevent corrosion of the metal flange and improve the overall durability and lifespan of the flange assembly.

In terms of replacing metals when tightening flanges, PA66 GF60 can be used as a non-metallic alternative to traditional metal fasteners. Its excellent mechanical properties, such as its high tensile strength and modulus of elasticity, make it a suitable choice for use in high load applications. Its low coefficient of friction also makes it a suitable choice for use in applications where low torque is required for tightening.

Manufacturing using harsh chemicals: PA66 GF60 is resistant to a wide range of chemicals, including acids, bases, and organic solvents. It is also resistant to hydrolysis, making it a suitable choice for use in wet environments. Its good chemical resistance makes it a suitable choice for use in harsh environments where it may be exposed to a variety of chemicals.

In terms of specific chemical resistance, PA66 GF60 is resistant to most acids, including hydrochloric acid, sulfuric acid, and nitric acid. It is also resistant to most organic solvents, including gasoline, diesel fuel, and oil. However, it is not resistant to strong bases, such as sodium hydroxide and potassium hydroxide, and it is also not resistant to some organic solvents, such as acetone and acetylene.
