PA66 FH772

Asahi Kasei Leona™ FH772 is a polyamide 66 (nylon 66) product filled with 25% glass fiber. Typical applications: Electrical/electronic applications.

Asahi Kasei Leona is a nylon 66 fiber known for its high strength, high heat resistance, and lightweight properties, widely used in industrial materials centered around the automotive industry. In particular, it serves as a fiber for airbags in the rapidly growing global automotive sector, as well as a reinforcement material for tires, including those for aircraft. The high quality of LEONA fiber is achieved through an ideal process called "continuous polymerization and direct spinning." Polyamide 66 "Leona™" resin is an engineering plastic resin with excellent heat resistance, strength, and rigidity, widely used in automotive parts, electrical and electronic components, office equipment parts, and construction material components.

Asahi Kasei Leona  is  Asahi Kasei  's  PA66  resin series. These products are engineering plastics with excellent heat resistance and mechanical strength. PA66  resin has a high melting point (265°C) among general-purpose engineering plastics and exhibits outstanding heat resistance.  PA66  resin has excellent strength and stiffness. The high toughness and excellent impact resistance of these materials are valuable characteristics. These properties stem from the molecular structure of PA66 resin, characterized by tightly interwoven polymer chains and hydrogen bonding between molecules; the water absorption of these materials causes them to exhibit water-induced plasticity (water molecules occupy amorphous sites). These characteristics make LEONA™ materials an effective alternative to metals.

PA66  resin has excellent electrical insulation and tracking resistance. These properties arise from the absence of benzene rings in the molecular structure of PA66 resin, making it less prone to carbonization.

PA66  resin has excellent resistance to non-acidic chemicals, organic solvents, lubricating oils, and similar substances. PA66  resin has high intermolecular cohesion and does not become brittle even when compounded with fillers. Plastics are often compounded with additives such as glass fiber (GF) and mineral fillers to enhance material strength, among other properties. However, large amounts of such additives can lead to embrittlement, reducing strength and impact resistance. Therefore, the amount of filler added to plastics has a **limit, which varies depending on the type of plastic.
